# Lasing and transport in a coupled quantum dot–resonator system

@article{Jin2012LasingAT, title={Lasing and transport in a coupled quantum dot–resonator system}, author={Pei-Qing Jin and Michael Marthaler and Jared H. Cole and Alexander Shnirman and Gerd Sch{\"o}n}, journal={Physica Scripta}, year={2012}, volume={T151} }

We investigate a double quantum dot coupled to a transmission line resonator. By driving a current through the double dot, a population inversion between the dot levels can be created, and a lasing state of the radiation field is generated within a sharp resonance window. The transport current correlates with the lasing state. The sharp resonance condition allows for resolving small differences in the dot properties. Dissipative processes in the quantum dots and their effect on the lasing and…
