Solutions to the Harmonic Oscillator Equation and Hermite Polynomials

In summary, Hermite polynomials are related to the solutions of the Schrodinger equation for a harmonic oscillator. They are not the solutions themselves, but rather the solutions are the product of a Hermite polynomial and an exponential function. The wavefunction for the n-th excited state of the harmonic oscillator can be expressed as the n-th Hermite polynomial multiplied by an exponential function. However, Hermite polynomials (or any polynomials) cannot be solutions to the Schrodinger equation over all values of x, as they are not normalizable. This means that while they are solutions to the equation, they are not physically meaningful. Being a solution to the Schrodinger equation and being normalizable are two different things.

How are Hermite Polynomials related to the solutions to the Schrodinger equation for a harmonic oscillator? Are they the solutions themselves, or are the solutions to the equation the product of a Hermite polynomial and an exponential function?

Thanks!

Wavefunction of the n-th excited state of the harmonic oscillator is equal to the n-th Hermite polynomial times [itex]{\large e^{-\frac{x^{2}}{4l}}}[/itex] where [itex]l = \sqrt{\frac{\hbar}{2m\omega}}[/itex]

The Hermite polynomials (or any polynomials for that matter) cannot be solutions of the SE over all x because they are not normalizable over all x.

1. What is the Harmonic Oscillator Equation?

The Harmonic Oscillator Equation is a mathematical model that describes the motion of a particle in a system where the restoring force is directly proportional to the displacement of the particle from its equilibrium position. It is represented by the equation F = -kx, where F is the restoring force, k is the spring constant, and x is the displacement of the particle.

2. What are the solutions to the Harmonic Oscillator Equation?

The solutions to the Harmonic Oscillator Equation are sinusoidal functions, also known as harmonic motion, which can be expressed as either sine or cosine functions. These solutions represent the position, velocity, and acceleration of the particle at any given time.

3. What are Hermite Polynomials?

Hermite Polynomials are a set of orthogonal polynomials that are often used as solutions to the Harmonic Oscillator Equation. They are named after the French mathematician Charles Hermite and are defined by a three-term recurrence relation.

4. How are Hermite Polynomials related to the Harmonic Oscillator Equation?

Hermite Polynomials are related to the Harmonic Oscillator Equation because they can be used to express the solutions of the equation in terms of polynomial functions. These polynomials allow for a more efficient and elegant way to solve the equation and describe the motion of the particle in the system.

5. What are some applications of the Harmonic Oscillator Equation and Hermite Polynomials?

The Harmonic Oscillator Equation and Hermite Polynomials have many applications in physics, engineering, and mathematics. They are commonly used to model and analyze systems such as vibrating strings, pendulums, and molecular vibrations. They are also used in quantum mechanics to describe the behavior of subatomic particles and in signal processing to analyze waveforms.
