Quantum detailed balance & exact solutions of interacting driven-dissipative systems
Aashish Clerk, Pritzker School of Molecular Engineering, The University of Chicago
I’ll discuss a new approach that allows one to non-perturbatively find the steady states of driven-dissipative systems described by a Lindblad master equation. The focus will be on driven nonlinear resonator systems, a class of system that is at the forefront of research in superconducting quantum circuits and quantum optics. I’ll discuss new phenomena revealed by these solutions, including a new kind of generalized photon blockade effect that is effective even for extremely weak system nonlinearity, and new mechanisms for quantum bistability (where there exists a manifold of possible steady states). I will also discuss the connection between the existence of these exact solutions and an operationally-useful definition of quantum detailed balance.
