    "abstract": "The prototypical Schr\\\"{o}dinger cat state, i.e., an initial state\ncorresponding to two widely separated Gaussian wave packets, is considered. The\ndecoherence time is calculated solely within the framework of elementary\nquantum mechanics and equilibrium statistical mechanics. This is at variance\nwith common lore that irreversible coupling to a dissipative environment is the\nmechanism of decoherence. Here, we show that, on the contrary, decoherence can\nin fact occur at high temperature even for vanishingly small dissipation.",
