Homework Statement
A particle of mass m is confined in a two-dimensions by the potential energy V = 1/2k(x2+4y2). Write down the Schrodinger equation for the system. Write down the ground state wave function and find the lowest four energy levels in terms of the quantities ħ, k, m etc. Make clear which, if any, of the levels is degenerate. Use any of the results you need from the one-dimensional harmonic oscillator without proof.
Homework Equations
Schrodinger's equation, two-dimensional:
[(-ħ/2m)(d2/d2x + d2/d2y) + V(x)] [itex]\psi[/itex]E(x,y)]=E [itex]\psi[/itex]E(x,y)
One-dimensional harmonic oscillator equations:
[itex]\psi[/itex]0 = (m[itex]\omega[/itex]0/ħ[itex]\pi[/itex])e-ax2
[itex]\omega[/itex]o=[itex]\sqrt{k/m}[/itex]
a=[itex]\sqrt{km}[/itex]/2ħ
En = (n+1/2)ħ[itex]\omega[/itex]0
The Attempt at a Solution
Schrodinger's equation:
[(-ħ2/2m)(d2/d2x + d2/d2y) + 1/2k(x2+4y2)] [itex]\psi[/itex]E(x,y)=E[itex]\psi[/itex]E(x,y)
After this I'm not really sure what to do. As for what to plug in where, and how to solve for the energy levels. Do I use the equation to solve for the energy levels? How?
