Energy eigenvalues and ground-state energy

Click For Summary
SUMMARY

The energy eigenvalues for a particle of mass, m, confined to a three-dimensional cube of side length a are defined by the equation E_{nx,ny,nz}=\frac{a(n^{2}_{x}+n^{2}_{y}+n^{2}_{z})}{b}+ Vo, where a is Planck's constant squared times pi squared, and b equals 2m squared. The ground-state kinetic energy can be calculated using the formula Ke = \frac{3a(n^{2}_{x})}{b}, while the potential energy can be derived by rearranging to Vo = E - \frac{3a(n^{2}_{x})}{b}. These relationships are crucial for understanding quantum mechanics in confined systems.

Homework Statement


The energy eigenvalues of a particles of mass, m, confined to a 3-d cube of side a are:

E_{nx,ny,nz}=\frac{a(n^{2}_{x}+n^{2}_{y}+n^{2}_{z})}{b}+ Vo

where:
a= planks constant^2(pi)^2
b=2m^2
nx,ny,nz = any positive integers.

What are the ground-state kinetic and potential energies of the particle.

The Attempt at a Solution


Really stumped. Any hints would be helpful thanks.

Try starting with the kinetic and potential energy operators.
 
So
Ke = 3a(n^{2}_{x}) /b ?

And Pe would be re-arranging to have Vo = E - 3a(n^{x}_{2} )/b
