Physics 880K20: Problem Set 4 Due Wednesday, February 22 by 5PM

... Due Wednesday, February 22 by 5PM 1. This problem applies to any system with harmonic oscillator modes, including real harmonic oscillators and photons, among others. Consider the Hamiltonian h̄ωa† a, where a† and a are the photon creation and annihilation operators. a† and a satisfy the commutation ...

... What can be measured in quantum mechanics? “Traditional” approach to quantum measurements: A quantum measurement is described by an observable, M, that is, a Hermitian operator acting on the state space of the system. Measuring a system prepared in an eigenstate of M gives the corresponding eigenva ...

... (e) Assuming that the spin-orbit interaction lifts the degeneracy of the states with different j, how many distinct energy levels make up the fine-structure of the (3p)2 state? The allowed j values are j = 0, 1, 2, so there would be 3 fine-structure levels. (f) Which j levels would shift if a contac ...

... This is interesting, but we must keep in mind a number of caveats: 1. the classical density is time-dependent, and we have chosen to average over the “natural” timescale in the system, if no such scale presented itself, we would be out of luck making these comparisons, 2. Our classical temporal aver ...
