Propagating large open quantum systems towards their asymptotic states: cluster implementation of the time-evolving block decimation scheme
Volokitin, V; Vakulchyk, Ihor; Kozinov, E; Liniov, A; Meyerov, I; Ivanchenko, Mikhail; Laptyeva, T; Denysov, Sergiy (Journal of Physics: Conference Series;Volume 1392, Journal article; Peer reviewed, 2019)Many-body quantum systems are subjected to the Curse of Dimensionality: The dimension of the Hilbert space H, where these systems live in, grows exponentially with number of their components. However, with some systems, ... -
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 ...
