Physics
Consider the time dependent HamiltonianH=H0+W(t).|φn is a basis of H0. Whent<0, the system is in one of the eigen states,|φi, of the unperturbedHamiltonian H0. At ?=0 an, a timedependent perturbationWt=Ccos(ωt) is appliedto the system for a sufficiently long time, here C is acomplex number and w is the angular frequency of theapplied perturbation. Calculate the probability of finding thesystem in |φf eigen states ofH0 when the system in resonanceω≈ωfi. Assume also thatEf-Eiâ„=ωfi>0.
