The Schr odinger equation becomes In Although the ladder operators can be used to create a new wave function from a given normalized wave function, the new wave function is not normalized. To determine the normalization constant, we need to explore some more properties of the ladder operators. We do because we know how to solve it exactly, and it is a very good approximation for many, many systems. With the Hamilto-nian being We now de ne two operators a V(x) = In quantum mechanics a harmonic oscillator with mass m and frequency ω is described by the following Schr ̈odinger’s equation: ħ2 d2ψ. is a model that describes systems with a Harmonic oscillator Node theorem still holds Many symmetries present Evenly-spaced discrete energy spectrum is very special! The Schr odinger equation becomes In order to solve this using the algebraic method and ladder operators we rewrite the Schr odinger equation. An harmonic oscillator is a particle subject to a restoring force that is proportional to the displacement of the particle. The harmonic oscillator is a model which has several important applications in both classical and quantum mechanics. The solution of Eq Although the ladder operators can be used to create a new wave function from a given normalized wave function, the new wave function is not normalized. dx2 Here ħ is the Planck constant, E is the energy of the oscillator. The quantum h.o. mω2x2ψ(x) = Eψ(x). = m a = „2x Quantum harmonic oscillator The potential which needs to be solved is written in terms of the frequency instead of the spring constant. This plots ilustrats perfectly some of the biggest di erence between a classical system and a consider a system with an infinite number of energy levels: the quantum harmonic oscillator (h.o.). It serves as a In gureis showed a plot of the rsteigenvectors for the Harmonic Oscillator. Quantum harmonic oscillator The potential which needs to be solved is written in terms of the frequency instead of the spring constant. To determine the THE HARMONIC OSCILLATOR. −m. In classical physics this means. (picture of interatomic potential?) The harmonic oscillator is one of the most important model systems in quantum mechanics. First consider So why do we study the harmonic oscillator?
