Thermal Coherent States and Thermal Squeezed States
J. Oz-Vogt, Adrian B. Mann, M. Revzen · Journal of Modern Optics · 1991
Various definitions of thermal coherent states and thermal squeezed states are compared and interrelated. Different ordering of squeezing, displacement and thermalizing operators is discussed in order to establish a relation between all definitions. A one-to-one correspondence is exhibited between general Gaussian density matrices in coordinate space and thermal squeezed states.
