So, I have to take the Hermite polynomials and calculate expectation values in integration method? Or, is there any other easier method to do this? So that I can verify Ehrenfest theorem.
Sorry, but I'm still getting the same $$2<p>$$result when I replaced ##a## and ##a^{\dagger}## by ##A## and ##A^{\dagger}## in expression for x and p and did the calculations. Why this "2" is coming in the expression? Is Ehrenfest theorem also not defined in this case?
I'm trying to check if Ehrenfest theorem is satisfied for this wave function,
|Y>=(1/sqrt(2))*(|1>+|3>),
where |1> and |3> are the ground and 1st exited state wave functions of a half harmonic oscillator. When I'm calculating the expectation values of x and p using annihilation creation...
Thanks. It's just my conception was not that clear. Will you check if I am right or not.
While moving through periodic potential when a electron gets attracted towards a positive center(i.e. zero potential area), it can be said that a hole is created in the high potential area where the...
Well I know what is effective mass, how it's expression is obtained, how it varies for electron with wavenumber 'k' (m* vs k graph). But can't understand why for hole the m* vs k graph is opposite to the graph of electron.
