Dynamics of a qubit coupled to a dissipative nonlinear quantum oscillator: an effective bath approach
Carmen Vierheilig, Dario Bercioux, Milena Grifoni
We consider a qubit coupled to a nonlinear quantum oscillator, the latter coupled to an Ohmic bath, and investigate the qubit dynamics. This composed system can be mapped onto that…
The dissipative quantum Duffing oscillator: a comparison of Floquet-based approaches
Carmen Vierheilig, Milena Grifoni
We study the dissipative quantum Duffing oscillator in the deep quantum regime with two different approaches: The first is based on the exact Floquet states of the linear oscillato…
Dissipative dynamics of a qubit coupled to a nonlinear oscillator
Carmen Vierheilig, Johannes Hausinger, Milena Grifoni
We consider the dissipative dynamics of a qubit coupled to a nonlinear oscillator (NO) embedded in an Ohmic environment. By treating the nonlinearity up to first order and applying…
