Probing microscopic models for system-bath interactions via parametric driving

Abstract:

We show that strong parametric driving of a quantum harmonic oscillator coupled to a thermal bath allows one to distinguish between different microscopic models for the oscillator-bath coupling. We consider a bath with an Ohmic spectral density and a model where the system-bath interaction can be tuned continuously between position and momentum coupling via the coupling angle α. We derive a master equation for the reduced density operator of the oscillator in Born-Markov approximation and inv...
