Dephasing-assisted Gain and Loss in Mesoscopic Quantum Systems
Dephasing-assisted Gain and Loss in Mesoscopic Quantum Systems
Motivated by recent experiments, we analyse the phonon-assisted steady-state gain of a microwave field driving a double quantum-dot in a resonator. We apply the results of our companion paper, which derives the complete set of fourth-order Lindblad dissipators using Keldysh methods, to show that resonator gain and loss are substantially …
