Solving Psi(x,t) for a Harmonic Oscillator

Click For Summary
SUMMARY

The discussion centers on solving the wave function Psi(x,t) for a harmonic oscillator, starting from the initial state Psi(x, 0) = Phi_n(x), where Phi_n(x) represents the nth solution of the time-independent Schrödinger equation (TISE). The solution for Psi(x, t) is derived from the time-dependent Schrödinger equation (TDSE) and is expressed as Psi(x, t) = Phi_n(x) * exp(iEt/ħ), where E is the energy eigenvalue and ħ is the reduced Planck's constant. This formulation highlights the separability of the TDSE and the relationship between the TISE and the time evolution of quantum states.

Hello,

A harmonic oscillator is in the initial state:
Psi(x, 0) = Phi_n (x)
where Phi_n(x) is the nth solution of the time-independent Schr¨odinger equation.
What is Psi(x, t)?

Any clue?

Thanks

Psi(x, t) is the solution of the time dependent Schrödinger equation (TDSE). The TDSE is a separable partial differential equation. More precisely, the solution to the TDSE is the product of the TISE and of \exp(iEt/\hbar)[/tex]:<br /> <br /> \Psi(x,t)=\psi(x)e^{iEt/\hbar}
 
Thanks a lot :):)
