On the time evolution of coherent states
By means of the density matrix method, the necessary and sufficient conditions for a coherent state to remain coherent at all times are discussed. It is shown that the conditions of Glauber are correct, the censure of Kano is groundless, and the conditions of Glauber are applicable for the Hamiltonian in quite general form.
