eXplainable Artificial Intelligence (XAI) in aging clock models
Alena Kalyakulina, Igor Yusipov, Alexey Moskalev +2
eXplainable Artificial Intelligence (XAI) is a rapidly progressing field of machine learning, aiming to unravel the predictions of complex models. XAI is especially required in sen…
Chaotic spin-photonic states in an open periodically modulated quantum cavity
I. I. Yusipov, S. V. Denisov, M. V. Ivanchenko
When applied to dynamical systems, both classical and quantum, time periodic modulations can produce complex non-equilibrium states which are often termed 'chaotic`. Being well und…
Transforming the Lindblad Equation into a System of Linear Equations: Performance Optimization and Parallelization of an Algorithm
Iosif Meyerov, Evgeny Kozinov, Alexey Liniov +4
With their constantly increasing peak performance and memory capacity, modern supercomputers offer new perspectives on numerical studies of open many-body quantum systems. These sy…
Quantum Neimark-Sacker bifurcation
Igor Yusipov, Mikhail Ivanchenko
Recently, it has been demonstrated that asymptotic states of open quantum system can undergo qualitative changes resembling pitchfork, saddle-node, and period doubling classical bi…
Photon waiting time distributions: a keyhole into dissipative quantum chaos
I. I. Yusipov, O. S. Vershinina, S. V. Denisov +1
Open quantum systems can exhibit complex states, which classification and quantification is still not well resolved. The Kerr-nonlinear cavity, periodically modulated in time by co…
Unfolding quantum master equation into a system of real-valued equations: computationally effective expansion over the basis of generators
A. Liniov, I. Meyerov, E. Kozinov +4
Dynamics of an open -state quantum system is typically modeled with a Markovian master equation describing the evolution of the system's density operator. By using generators of…
LUDB: a new open-access validation tool for electrocardiogram delineation algorithms
Alena I. Kalyakulina, Igor I. Yusipov, Victor A. Moskalenko +5
We report Lobachevsky University Database (LUDB) of ECG signals, an open tool for validating ECG delineation algorithms, that is superior to the existing publicly available data ba…
Finding morphology points of electrocardiographic signal waves using wavelet analysis
Alena I. Kalyakulina, Igor I. Yusipov, Victor A. Moskalenko +4
A new algorithm has been developed for delineation of significant points of various electrocardiographic signal (ECG) waves, taking into account information from all available lead…
Lyapunov exponents of quantum trajectories beyond continuous measurements
I. I. Yusipov, O. S. Vershinina, S. V. Denisov +2
Quantum systems interacting with their environments can exhibit complex non-equilibrium states that are tempting to be interpreted as quantum analogs of chaotic attractors. Yet, de…
Quantum jumps on Anderson attractors
I. I. Yusipov, T. V. Laptyeva, M. V. Ivanchenko
In a closed single-particle quantum system, spatial disorder induces Anderson localization of eigenstates and halts wave propagation. The phenomenon is vulnerable to interaction wi…
Control of a single-particle localization in open quantum systems
O. S. Vershinina, I. I. Yusipov, S. Denisov +2
We investigate the possibility to control localization properties of the asymptotic state of an open quantum system with a tunable synthetic dissipation. The control mechanism reli…
Localization in open quantum systems
I. Yusipov, T. Laptyeva, S. Denisov +1
In an isolated single-particle quantum system a spatial disorder can induce Anderson localization. Being a result of interference, this phenomenon is expected to be fragile in the…
