Time-dependent Superposition and Expectation Values: Infinite Square Well

(Illustration)

n1 =       n2 =    
 

The superposition shown is an equal mix of the two states n1 and n2 for the infinite square well, Yn1n2(x,t)=(1/2)-1/2 [fn1 (x,t) + fn2 (x,t)].  Change the state and watch DxDp---written as dxdp---measured in hbar, change with time.

Look at what happens to the wave function and the expectation values when both n1 and n2 are even or odd.
