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…
Superoperator master equations for depolarizing dynamics
A. E. Teretenkov
The work is devoted to superoperator master equations. Namely, the superoperator master equations in the case of the twirling hyperprojector with respect to the whole unitary group…
Effective Heisenberg equations for quadratic Hamiltonians
A. E. Teretenkov
We discuss effective quantum dynamics obtained by averaging projector with respect to free dynamics. For unitary dynamics generated by quadratic fermionic Hamiltonians we obtain ef…
