Ground state of harmonic oscillator

Click For Summary
SUMMARY

The discussion focuses on verifying that the ground state wavefunction (n=0) of the harmonic oscillator is an eigenstate of the Hamiltonian. The explicit wavefunction is given as \\Psi_{0}(x)=1/(\pi^{1/4}\sqrt{x_{0}})*e^{-x^2/2x^{2}_{0}}. Participants are tasked with calculating the average potential energy <0|\hat{v}|0> and average kinetic energy <0|\hat{T}|0> using this wavefunction. The integral for the average values is provided, emphasizing the importance of the correct application of quantum mechanics principles.

Homework Statement


Verify that the ground state (n=0) wavefunction is an eigenstate of the harmonic
oscillator Hamiltonian. Using the explicit wavefunction of the ground state to calculate
the average potential energy <0|[tex]\hat{v}[/tex]|0> and average kinetic energy <0|[tex]\hat{T}[/tex]| 0>


Homework Equations



[tex]\int^{\infty}_{0}[/tex](x[tex]^{2n}[/tex] e[tex]^{-ax^{2}}[/tex])dx=[tex]\frac{1x3x5x...x(2n-1)}{2^(n+1)a^n}[/tex][tex]\sqrt{\frac{\pi}{a}}[/tex]


The Attempt at a Solution


I did the ground state harmonic oscillation standard alteration with "a" and got [tex]\\Psi_{0}[/tex](x)=1/([tex]\pi^{1/4}[/tex][tex]\sqrt{x_{0}}[/tex])*e^-x^2/2x[tex]^{2}_{0}[/tex]

You're going to have to make a bit more of an effort to work the problem on your own before you'll get any help here.
 
ill just go ask this question another website, thanx
