Quantum Pump Depletion and Multicomponent Schrödinger-Cat-Like States in Doubly Pumped Intraresonance Kerr Microresonators
Ranjit Singh, Alexander E. Teretenkov
We investigate quantum pump depletion and non-Gaussian state generation in doubly pumped Kerr microresonators operating in the intraresonance regime. The pump modes are treated qua…
Generation of Schrödinger cat-like states via degenerate dual pump spontaneous four-wave mixing in a microring resonator
Ranjit Singh, Alexander E. Teretenkov
We theoretically investigate the generation of non-Gaussian quantum states, specifically Schrödinger cat-like states (SCLSs), via degenerate dual-pump spontaneous four-wave mixing…
Gaussian approximation and its corrections for driven dissipative Kerr model
K. Sh. Meretukov, A. E. Teretenkov
We develop a systematic projection-operator technique for constructing Gaussian approximations and their perturbative corrections in bosonic nonlinear models. As a case study, we a…
Long-time behavior of multi-level open systems interacting with non-vacuum reservoirs
A. E. Teretenkov
The model of multi-level open quantum system interacting with a non-vacuum reservoir in the rotating wave approximation is considered. We provide an exact integral representation f…
