1. The problem statement, all variables and given/known data At t=0 the wave function of a two-dimensional isotropic harmonic oscilator is ψ(x,y,0)=A(4α^2 x^2+2αy+4α^2 xy-2) e^((-α^2 x^2)/2) e^((-α^2 y^2)/2) where A its the normalization constant In wich instant. Wich values of total energy can we find and which probability? 2. Relevant equations None 3. The attempt at a solution I dont know how to start it.
