    "abstract": "Motivated by recent experiments, we consider a Schr\\\"{o}dinger cat\nsuperposition of two widely separated coherent states in thermal equilibrium.\nThe time development of our system is obtained using Wigner distribution\nfunctions. In contrast to our discussion for a two-Gaussian wave packet [Phys.\nLett. A 286 (2001) 87], we find that, in the absence of dissipation, the\ninterference term does not decay rapidly in time, but in common with the other\ntwo terms, it oscillates in time and persists for all times",
