Photon waiting-time distributions: A keyhole into dissipative quantum chaos
Yusipov, Igor; Vershinina, Olga; Denysov, Sergiy; Ivanchenko, Mikhail (Chaos;Volume 30, Issue 2, Journal article; Peer reviewed, 2020-01-14)Open quantum systems can exhibit complex states, for which classification and quantification are still not well resolved. The Kerr-nonlinear cavity, periodically modulated in time by coherent pumping of the intracavity ... -
Quantum Lyapunov exponents beyond continuous measurements
Yusipov, Igor; Vershinina, Olga; Denysov, Sergiy; Kuznetsov, Sergey; Ivanchenko, Mikhail (Chaos;Volume 29, Issue 6, Journal article; Peer reviewed, 2019-10-28)Quantum systems, when interacting with their environments, may exhibit non-equilibrium states that are tempting to be interpreted as quantum analogs of chaotic attractors. However, different from the Hamiltonian case, the ... -
Transforming Lindblad Equations Into Systems of Real-Valued Linear Equations: Performance Optimization and Parallelization of an Algorithm
Meyerov, I; Kozinov, E; Liniov, A; Volokitin, V; Yusipov, Igor; Ivanchenko, Mikhail; Denysov, Sergiy (Entropy;Volume 22, Issue 10, Journal article; Peer reviewed, 2020-10-06)With their constantly increasing peak performance and memory capacity, modern supercomputers offer new perspectives on numerical studies of open many-body quantum systems. These systems are often modeled by using Markovian ... -
Unfolding a quantum master equation into a system of real-valued equations: Computationally effective expansion over the basis of SU(N) generators
Liniov, A; Meyerov, I; Kozinov, E; Volokitin, V; Yusipov, Igor; Ivanchenko, Mikhail; Denysov, Sergiy (Physical Review E;Volume 100, Issue 5 — November 2019, Journal article; Peer reviewed, 2019-11-11)Dynamics of an open N-state quantum system is often modeled with a Markovian master equation describing the evolution of the system density operator. By using generators of SU(N) group as a basis, the density operator can ...
