Random Phase Infinite Coherent States: Construction and Dynamics
Résumé
We consider an infinitely extended reservoir of Boson coherent states characterized by a given spatial density of modes and i.i.d. random phases. We construct its Hilbert space representation which has a random part and is expressed by means of Ito stochastic integrals. We study the open system dynamics of an N-level system coupled to the random infinite coherent state by an energy conserving interaction. We show that the coherent state reservoir induces faster system decoherence than a thermal reservoir.
