Abstract

In recent years, there has been rapid development in control and manipulation of coherent quantum systems. These advances allow for the study and utilization of coherent quantum phenomena, as well as the exploration of novel quantum mechanical concepts in realistic many-body setups. Such coherent effects are always impacted by coupling to an environment. In my talk, I will introduce several cases where the environment competes with the coherent system and induces novel population inversions, or completely alters the closed system's signatures. Specifically, I will start by showing how dissipation in driven nonlinear bosonic cavities leads to a dramatic change of the phase diagram, and then move on to generalize such effects in light-matter systems. I will then move to discuss the impact of non-Ohmic noise on coherent transport signatures in quantum wires, and conclude with showing how quantum measurement backaction can induce a population switching in a double quantum dot device.
