Abstract
The interaction between quantum light and matter is being intensively studied for systems that are enclosed in high-\$Q\$ cavities which strongly enhance the light-matter coupling. However, for many applications, cavities with lower \$Q\$-factors are preferred due to the increased spectral width of the cavity mode. Here, we investigate the interaction between quantum light and matter represented by a \$\Lambda\$-type three-level system in lossy cavities, assuming that cavity losses are the dominant loss mechanism. We demonstrate that cavity losses lead to non-trivial steady states of the electronic occupations that can be controlled by the loss rate and the initial statistics of the quantum fields. The mechanism of formation of such steady states can be understood on the basis of the equations of motion. Analytical expressions for steady states and their numerical simulations are presented and discussed.
