Decoherence without dissipation
G. W. Ford, R. F. O'Connell
abstract: The prototypical Schr\"{o}dinger cat state, i.e., an initial state
corresponding to two widely separated Gaussian wave packets, is considered. The
decoherence time is calculated solely within the framework of elementary
quantum mechanics and equilibrium statistical mechanics. This is at variance
with common lore that irreversible coupling to a dissipative environment is the
mechanism of decoherence. Here, we show that, on the contrary, decoherence can
in fact occur at high temperature even for vanishingly small dissipation.
