Conformal map

Some trajectories of a harmonic oscillator according to Newton's laws of classical mechanics (A-B), and according to the Schrödinger equation of quantum mechanics (C-H). In (A-B), the particle (represented as a ball attached to a spring) oscillates back and forth. In (C-H), some solutions to the Schrödinger Equation are shown, where the horizontal axis is position, and the vertical axis is the real part (blue) or imaginary part (red) of the wavefunction. (C,D,E,F), but not (G,H), are energy eigenstates. (H) is a coherent state, a quantum state which approximates the classical trajectory.

The quantum harmonic oscillator is the quantum-mechanical analog of the classical harmonic oscillator. Because an arbitrary potential can usually be approximated as a harmonic potential at the vicinity of a stable equilibrium point, it is one of the most important model systems in quantum mechanics. Furthermore, it is one of the few quantum-mechanical systems for which an exact, analytical solution is known.

Hamiltonian and energy eigenstates

Wavefunction representations for the first eight bound eigenstates, n = 0 to 7. The horizontal axis shows the position x. Note: The graphs are not normalized, and the signs of some of the functions differ from those given in the text.

Corresponding probability densities.

The Hamiltonian of the particle is:

${\hat {H}}={\frac {{\hat {p}}^{2}}{2m}}+{\frac {1}{2}}m\omega ^{2}{\hat {x}}^{2}\,,$

where m is the particle's mass, ω is the angular frequency of the oscillator, ${\hat {x}}=x$ is the position operator, and ${\hat {p}}$ is the momentum operator, given by

${\hat {p}}=-i\hbar {\partial \over \partial x}\,.$

The first term in the Hamiltonian represents the possible kinetic energy states of the particle, and the second term represents its respectively corresponding possible potential energy states.

One may write the time-independent Schrödinger equation,

${\hat {H}}\left|\psi \right\rangle =E\left|\psi \right\rangle \,,$

where Template:Mvar denotes a yet-to-be-determined real number that will specify a time-independent energy level, or eigenvalue, and the solution |ψ⟩ denotes that level's energy eigenstate.

One may solve the differential equation representing this eigenvalue problem in the coordinate basis, for the wave function ⟨x|ψ⟩ = ψ(x), using a spectral method. It turns out that there is a family of solutions. In this basis, they amount to

$\psi _{n}(x)={\frac {1}{\sqrt {2^{n}\,n!}}}\cdot \left({\frac {m\omega }{\pi \hbar }}\right)^{1/4}\cdot e^{-{\frac {m\omega x^{2}}{2\hbar }}}\cdot H_{n}\left({\sqrt {\frac {m\omega }{\hbar }}}x\right),\qquad n=0,1,2,\ldots .$

The functions H_n are the Hermite polynomials,

$H_{n}(x)=(-1)^{n}e^{x^{2}}{\frac {d^{n}}{dx^{n}}}\left(e^{-x^{2}}\right)$ .

The corresponding energy levels are

$E_{n}=\hbar \omega \left(n+{1 \over 2}\right)$ .

This energy spectrum is noteworthy for three reasons. First, the energies are quantized, meaning that only discrete energy values (integer-plus-half multiples of Buying, selling and renting HDB and personal residential properties in Singapore are simple and transparent transactions.

Because of the zero-point energy, the position and momentum of the oscillator in the ground state are not fixed (as they would be in a classical oscillator), but have a small range of variance, in accordance with the Heisenberg uncertainty principle. The zero-point energy also has important implications in quantum field theory and quantum gravity.

Note that the ground state probability density is concentrated at the origin. This means the particle spends most of its time at the bottom of the potential well, as we would expect for a state with little energy. As the energy increases, the probability density becomes concentrated at the classical "turning points", where the state's energy coincides with the potential energy. This is consistent with the classical harmonic oscillator, in which the particle spends most of its time (and is therefore most likely to be found) at the turning points, where it is the slowest. The correspondence principle is thus satisfied.

Probability densities |ψ_n(x)|² for the bound eigenstates, beginning with the ground state (n = 0) at the bottom and increasing in energy toward the top. The horizontal axis shows the position x, and brighter colors represent higher probability densities.

The spectral method solution, though straightforward, is rather tedious. The "ladder operator" method, developed by Paul Dirac, allows us to extract the energy eigenvalues without directly solving the differential equation.

For this reason, they are sometimes referred to as "creation" and "annihilation" operators.

From the relations above, we can also define a number operator Template:Mvar, which has the following property:

$N=a^{\dagger }a$

$N\left|n\right\rangle =n\left|n\right\rangle$ .

The following commutators can be easily obtained by substituting the canonical commutation relation,

$[a,a^{\dagger }]=1,\qquad [N,a^{\dagger }]=a^{\dagger },\qquad [N,a]=-a,$

And the Hamilton operator can be expressed as

$H=\left(N+{\frac {1}{2}}\right)\hbar \omega ,$

so the eigenstate of Template:Mvar is also the eigenstate of energy.

The commutation property yields

${\begin{aligned}Na^{\dagger }|n\rangle &=\left(a^{\dagger }N+[N,a^{\dagger }]\right)|n\rangle \\&=\left(a^{\dagger }N+a^{\dagger }\right)|n\rangle \\&=(n+1)a^{\dagger }|n\rangle ,\end{aligned}}$

and similarly,

$Na|n\rangle =(n-1)a|n\rangle .$

$n=\langle n|N|n\rangle =\langle n|a^{\dagger }a|n\rangle =\left(a|n\rangle \right)^{\dagger }a|n\rangle \geqslant 0,$

the smallest eigen-number is 0, and

$a\left|0\right\rangle =0$.

In this case, subsequent applications of the lowering operator will just produce zero kets, instead of additional energy eigenstates. Furthermore, we have shown above that

$H\left|0\right\rangle ={\frac {\hbar \omega }{2}}\left|0\right\rangle$

Finally, by acting on |0⟩ with the raising operator and multiplying by suitable normalization factors, we can produce an infinite set of energy eigenstates

$\left\{\left|0\right\rangle ,\left|1\right\rangle ,\left|2\right\rangle ,...,\left|n\right\rangle ,...\right\}$,

such that

$H\left|n\right\rangle =\hbar \omega \left(n+{\frac {1}{2}}\right)\left|n\right\rangle$ ,

which matches the energy spectrum given in the preceding section.

Arbitrary eigenstates can be expressed in terms of |0⟩,

$|n\rangle ={\frac {\left(a^{\dagger }\right)^{n}}{\sqrt {n!}}}|0\rangle$ .

Proof:

${\begin{aligned}\langle n|aa^{\dagger }|n\rangle &=\langle n|\left([a,a^{\dagger }]+a^{\dagger }a\right)|n\rangle =\langle n|\left(N+1\right)|n\rangle =n+1\\\Rightarrow a^{\dagger }|n\rangle &={\sqrt {n+1}}|n+1\rangle \\\Rightarrow |n\rangle &={\frac {a^{\dagger }}{\sqrt {n}}}|n-1\rangle ={\frac {\left(a^{\dagger }\right)^{2}}{\sqrt {n(n-1)}}}|n-2\rangle =\cdots ={\frac {\left(a^{\dagger }\right)^{n}}{\sqrt {n!}}}|0\rangle .\end{aligned}}$

The ground state |0⟩ in the position representation is determined by a |0⟩ = 0,

${\begin{aligned}&\left\langle x\left|a\right|0\right\rangle =0~~~~~~~~~~\Longrightarrow \\&\left(x+{\frac {\hbar }{m\omega }}{\frac {d}{dx}}\right)\left\langle x|0\right\rangle =0~~~~~~\Longrightarrow \\&\left\langle x|0\right\rangle =\left({\frac {m\omega }{\pi \hbar }}\right)^{\frac {1}{4}}\exp \left(-{\frac {m\omega }{2\hbar }}x^{2}\right)=\psi _{0}~,\end{aligned}}$

and hence

$\langle x|a^{\dagger }|0\rangle =\psi _{1}~,$

and so on, as in the previous section.

To avoid confusion, we will not adopt these "natural units" in this article. However, they frequently come in handy when performing calculations, by bypassing clutter.

Phase space solutions

In the phase space formulation of quantum mechanics, solutions to the quantum harmonic oscillator in several different representations of the quasiprobability distribution can be written in closed form. The most widely used of these is for the Wigner function, which has the solution

$F_{n}(u)={\frac {(-1)^{n}}{\pi \hbar }}L_{n}\left(4{\frac {u}{\hbar \omega }}\right)e^{-2u/\hbar \omega }~,$

where

$u={\frac {1}{2}}m\omega ^{2}x^{2}+{\frac {p^{2}}{2m}}$

and L_n are the Laguerre polynomials. This example shows how the Hermite polynomials and Laguerre polynomials are interrelated through the Wigner–Weyl transform.

N-dimensional harmonic oscillator

The one-dimensional harmonic oscillator is readily generalizable to N dimensions, where N = 1, 2, 3, ... . In one dimension, the position of the particle was specified by a single coordinate, x. In N dimensions, this is replaced by N position coordinates, which we label x₁, ..., x_N. Corresponding to each position coordinate is a momentum; we label these p₁, ..., p_N. The canonical commutation relations between these operators are

${\begin{matrix}\left[x_{i},p_{j}\right]&=&i\hbar \delta _{i,j}\\\left[x_{i},x_{j}\right]&=&0\\\left[p_{i},p_{j}\right]&=&0\end{matrix}}$.

The Hamiltonian for this system is

$H=\sum _{i=1}^{N}\left({p_{i}^{2} \over 2m}+{1 \over 2}m\omega ^{2}x_{i}^{2}\right)$.

As the form of this Hamiltonian makes clear, the N-dimensional harmonic oscillator is exactly analogous to N independent one-dimensional harmonic oscillators with the same mass and spring constant. In this case, the quantities x₁, ..., x_N would refer to the positions of each of the N particles. This is a convenient property of the $r^{2}$ potential, which allows the potential energy to be separated into terms depending on one coordinate each.

This observation makes the solution straightforward. For a particular set of quantum numbers {n} the energy eigenfunctions for the N-dimensional oscillator are expressed in terms of the 1-dimensional eigenfunctions as:

$\langle \mathbf {x} |\psi _{\{n\}}\rangle =\prod _{i=1}^{N}\langle x_{i}|\psi _{n_{i}}\rangle$

In the ladder operator method, we define N sets of ladder operators,

${\begin{matrix}a_{i}&=&{\sqrt {m\omega \over 2\hbar }}\left(x_{i}+{i \over m\omega }p_{i}\right)\\a_{i}^{\dagger }&=&{\sqrt {m\omega \over 2\hbar }}\left(x_{i}-{i \over m\omega }p_{i}\right)\end{matrix}}$.

By a procedure analogous to the one-dimensional case, we can then show that each of the a_i and a^†_i operators lower and raise the energy by ℏω respectively. The Hamiltonian is

$H=\hbar \omega \,\sum _{i=1}^{N}\left(a_{i}^{\dagger }\,a_{i}+{\frac {1}{2}}\right).$

This Hamiltonian is invariant under the dynamic symmetry group U(N) (the unitary group in N dimensions), defined by

$U\,a_{i}^{\dagger }\,U^{\dagger }=\sum _{j=1}^{N}a_{j}^{\dagger }\,U_{ji}\quad {\hbox{for all}}\quad U\in U(N),$

where $U_{ji}$ is an element in the defining matrix representation of U(N).

The energy levels of the system are

$E=\hbar \omega \left[(n_{1}+\cdots +n_{N})+{N \over 2}\right]$.

$n_{i}=0,1,2,\dots \quad ({\hbox{the energy level in dimension }}i).$

As in the one-dimensional case, the energy is quantized. The ground state energy is N times the one-dimensional energy, as we would expect using the analogy to N independent one-dimensional oscillators. There is one further difference: in the one-dimensional case, each energy level corresponds to a unique quantum state. In N-dimensions, except for the ground state, the energy levels are degenerate, meaning there are several states with the same energy.

The degeneracy can be calculated relatively easily. As an example, consider the 3-dimensional case: Define n = n₁ + n₂ + n₃. All states with the same n will have the same energy. For a given n, we choose a particular n₁. Then n₂ + n₃ = n − n₁. There are n − n₁ + 1 possible groups {n₂, n₃}. n₂ can take on the values 0 to n − n₁, and for each n₂ the value of n₃ is fixed. The degree of degeneracy therefore is:

$g_{n}=\sum _{n_{1}=0}^{n}n-n_{1}+1={\frac {(n+1)(n+2)}{2}}$

Formula for general N and n [g_n being the dimension of the symmetric irreducible n^th power representation of the unitary group U(N)]:

$g_{n}={\binom {N+n-1}{n}}$

The special case N = 3, given above, follows directly from this general equation. This is however, only true for distinguishable particle, or one particle in N dimensions (as dimensions are distinguishable). For the case of N bosons in a one dimension harmonic trap, the degeneracy scales as the number of ways to partition an integer n using integers less than or equal to N.

$g_{n}=p(N_{-},n)$

This arises due to the constraint of putting N quanta into a state ket where $\sum _{k=0}^{\infty }kn_{k}=n$ and $\sum _{k=0}^{\infty }n_{k}=N$, which are the same constraints as in integer partition.

Example: 3D isotropic harmonic oscillator

The Schrödinger equation of a spherically-symmetric three-dimensional harmonic oscillator can be solved explicitly by separation of variables, see this article for the present case. This procedure is analogous to the separation performed in the hydrogen-like atom problem, but with the spherically symmetric potential

$V(r)={1 \over 2}\mu \omega ^{2}r^{2},$

where $\mu$ is the mass of the problem. (Because m will be used below for the magnetic quantum number, mass is indicated by $\mu$, instead of m, as earlier in this article.)

The solution reads

$\psi _{klm}(r,\theta ,\phi )=N_{kl}r^{l}e^{-\nu r^{2}}{L_{k}}^{(l+{1 \over 2})}(2\nu r^{2})Y_{lm}(\theta ,\phi )$

where

$N_{kl}={\sqrt {{\sqrt {\frac {2\nu ^{3}}{\pi }}}{\frac {2^{k+2l+3}\;k!\;\nu ^{l}}{(2k+2l+1)!!}}}}\,$ is a normalization constant.

$\nu \equiv {\mu \omega \over 2\hbar }$

${L_{k}}^{(l+{1 \over 2})}(2\nu r^{2})$

are generalized Laguerre polynomials. The order k of the polynomial is a non-negative integer.

$Y_{lm}(\theta ,\phi )\,$ is a spherical harmonic function.

$\hbar$ is the reduced Planck constant: $\hbar \equiv {\frac {h}{2\pi }}$.

The energy eigenvalue is

$E=\hbar \omega \left(2k+l+{\frac {3}{2}}\right)~.$

The energy is usually described by the single quantum number

$n\equiv 2k+l~.$

Because k is a non-negative integer, for every even n we have $l=0,2...,n-2,n$ and for every odd n we have $l=1,3...,n-2,n$. The magnetic quantum number m is an integer satisfying $-l\leq m\leq l$, so for every n and l there are 2l+1 different quantum states, labeled by m. Thus, the degeneracy at level n is

$\sum _{l=\ldots ,n-2,n}(2l+1)={(n+1)(n+2) \over 2}~,$

where the sum starts from 0 or 1, according to whether n is even or odd. This result is in accordance with the dimension formula above, and amounts to the dimensionality of a symmetric representation of SU(3), the relevant degeneracy group.

Harmonic oscillators lattice: phonons

We can extend the notion of harmonic oscillator to a one lattice of many particles. Consider a one-dimensional quantum mechanical harmonic chain of N identical atoms. This is the simplest quantum mechanical model of a lattice, and we will see how phonons arise from it. The formalism that we will develop for this model is readily generalizable to two and three dimensions.

As in the previous section, we denote the positions of the masses by $x_{1},x_{2},...$, as measured from their equilibrium positions (i.e. $x_{i}=0$ if the particle Template:Mvar is at its equilibrium position.) In two or more dimensions, the $x_{i}$ are vector quantities. The Hamiltonian for this system is

$\mathbf {H} =\sum _{i=1}^{N}{p_{i}^{2} \over 2m}+{1 \over 2}m\omega ^{2}\sum _{\{ij\}(nn)}(x_{i}-x_{j})^{2}\$

where Template:Mvar is the mass of each atom (assuming is equal for all), and $\,x_{i}$ and $\,p_{i}$ are the position and momentum operators for the ith atom and the sum is made over the nearest neighbors (nn). However, as one expect, in a lattice could also appear waves that could behave as particles. For the treatment of waves, is custom to treat with the fourier space which uses normal modes of the wavevector as variables instead coordinates of particles. The number of normal modes are the same to the particles however the fourier space are very useful given the periodicity of the system.

We introduce, then, a set of Template:Mvar "normal coordinates" $\,Q_{k}$, defined as the discrete Fourier transforms of the Template:Mvars, and Template:Mvar "conjugate momenta" Template:Mvar defined as the Fourier transforms of the Template:Mvars:

$Q_{k}={1 \over {\sqrt {N}}}\sum _{l}e^{ikal}x_{l}$

$\Pi _{k}={1 \over {\sqrt {N}}}\sum _{l}e^{-ikal}p_{l}.$

The quantity $\,k_{n}$ will turn out to be the wave number of the phonon, i.e. 2π divided by the wavelength. It takes on quantized values, because the number of atoms is finite.

This choice retains the desired commutation relations in either real space or wave vector space

${\begin{aligned}\left[x_{l},p_{m}\right]&=i\hbar \delta _{l,m}\\\left[Q_{k},\Pi _{k'}\right]&={1 \over N}\sum _{l,m}e^{ikal}e^{-ik'am}[x_{l},p_{m}]\\&={i\hbar \over N}\sum _{m}e^{iam\left(k-k'\right)}=i\hbar \delta _{k,k'}\\\left[Q_{k},Q_{k'}\right]&=\left[\Pi _{k},\Pi _{k'}\right]=0\end{aligned}}$

From the general result

${\begin{aligned}\sum _{l}x_{l}x_{l+m}&={1 \over N}\sum _{kk'}Q_{k}Q_{k'}\sum _{l}e^{ial\left(k+k'\right)}e^{iamk'}=\sum _{k}Q_{k}Q_{-k}e^{iamk}\\\sum _{l}{p_{l}}^{2}&=\sum _{k}\Pi _{k}\Pi _{-k}.\end{aligned}}$

It is easy to show that the potential energy term is

${1 \over 2}m\omega ^{2}\sum _{j}(x_{j}-x_{j+1})^{2}={1 \over 2}\omega ^{2}\sum _{k}Q_{k}Q_{-k}(2-e^{ika}-e^{-ika})={1 \over 2}\sum _{k}{\omega _{k}}^{2}Q_{k}Q_{-k},$

where

$\omega _{k}={\sqrt {2\omega ^{2}(1-\cos(ka))}}.\$

The Hamiltonian may be written in wave vector space as

$\mathbf {H} ={1 \over {2m}}\sum _{k}\left({\Pi _{k}\Pi _{-k}}+m^{2}\omega _{k}^{2}Q_{k}Q_{-k}.\right)$

Note that the couplings between the position variables have been transformed away; if the Template:Mvars and Template:Mvars were hermitian(which they are not), the transformed Hamiltonian would describe Template:Mvar uncoupled harmonic oscillators.

The form of the quantization depends on the choice of boundary conditions; for simplicity, we impose periodic boundary conditions, defining the Buying, selling and renting HDB and personal residential properties in Singapore are simple and transparent transactions.

In comparison to the photon case when the electromagnetic field is quantised, the quantum of vibrational energy is called a phonon.

All quantum systems show wave-like and particle-like properties. The particle-like properties of the phonon are best understood using the methods of second quantization and operator techniques described later.

• The vibrations of a diatomic molecule are an example of a two-body version of the quantum harmonic oscillator. In this case, the angular frequency is given by

$\omega ={\sqrt {\frac {k}{\mu }}}$

where $\mu$ is the reduced mass and is determined by the mass of the two atoms.
