摘要：

Using the maximum-entropy approach, we analyze the appearance of coherent and squeezed states for the Kanai-Caldirola Hamiltonian, making it possible to extend the analysis easily to the so-called generalized harmonic oscillator and a sort of two-photon Hamiltonian, for both the zero and nonzero temperature cases. A connection between the possibility of obtaining squeezing and the relevant operators included in the density matrix is shown. Finally, a comparison with pertinent previous results in the literature is also presented. © 1990 The American Physical Society.
