Total quantum Zeno effect beyond Zeno time

Mundarain D.; STEPHANY, J; ORSZAG, M

Abstract

In this work we show that is possible to obtain Total Quantum Zeno Effect in an ustable systems for times larger than the correlation time of the bath. The effect is observed for some particular systems in which one can chose appropriate observables which frequent measurements freeze the system into the initial state. For a two level system in a squeezed bath one can show that there are two bath dependent observables displaying Total Zeno Effect when the system is initialized in some particular states. We show also that these states are intelligent states of two conjugate observables associated to the electromagnetic fluctuations of the bath. © 2007 IOP Publishing Ltd.
