A Phase in a Coherent State Wave Function - Is It Always Irrelevant?
arXiv:quant-ph/9810036 · doi:10.1088/0143-0807/20/3/007
Abstract
We point out that harmonic oscillator coherent states, in coordinate representation, require particular phase factor, in order to represent classical time evolution properly. The presence of such a phase is clearly stated only in a minority of scientific sources discussing properties of coherent states.
