Quantum Mechanics (Advance physics)

A coherent state of the electromagnetic field is given by 00 la) = e-lol?/2 E Inka). 1. Calculate (nkx) and Anka = V(n) - ("kx) for the coherent state. 2. Calculate (a Bja) and verify that the expectation values of B and E obey Faraday's law. Note: We saw in class that (a Ea) = -2\\ lolex A sin (k . x - wt + 8)
