Weak random periodic solutions of random dynamical systems

open access: yesCanadian Mathematical Bulletin, 2023
AbstractWe first introduce the concept of weak random periodic solutions of random dynamical systems. Then, we discuss the existence of such periodic solutions. Further, we introduce the definition of weak random periodic measures and study their relationship with weak random periodic solutions.

Theory of the Loschmidt echo and dynamical quantum phase transitions in disordered Fermi systems

open access: yesPhysical Review Research, 2023
In this work we develop the theory of the Loschmidt echo and dynamical phase transitions in noninteracting strongly disordered Fermi systems after a quench.

On the Criticality of Adaptive Boolean Network Robots

open access: yesEntropy, 2022
Systems poised at a dynamical critical regime, between order and disorder, have been shown capable of exhibiting complex dynamics that balance robustness to external perturbations and rich repertoires of responses to inputs.

Anomalous correlation-induced dynamical phase transitions

open access: yesScientific Reports, 2023
The nonanalyticity of the Loschmidt echo at critical times in quantum quenched systems is termed as the dynamical quantum phase transition, extending the notion of quantum criticality to a nonequilibrium scenario.

Distributional chaos in random dynamical systems [PDF]

open access: yesJournal of Difference Equations and Applications, 2019
In this paper, we introduce the notion of distributional chaos and the measure of chaos for random dynamical systems generated by two interval maps. We give some sufficient conditions for a zero measure of chaos and examples of chaotic systems. We demonstrate that the chaoticity of the functions that generate a system does not, in general, affect the ...

Conditional random matrix ensembles and the stability of dynamical systems

open access: yesNew Journal of Physics, 2015
Random matrix theory (RMT) has found applications throughout physics and applied mathematics, in subject areas as diverse as communications networks, population dynamics, neuroscience, and models of the banking system.

Quantum State Tomography in Nonequilibrium Environments

open access: yesPhotonics, 2023
We generalize an approach to studying the quantum state tomography (QST) of open systems in terms of the dynamical map in Kraus representation within the framework of dynamic generation of informationally complete positive operator-valued measures.

Upper semicontinuity of random attractors for non-compact random dynamical systems

open access: yesElectronic Journal of Differential Equations, 2009
The upper semicontinuity of random attractors for non-compact random dynamical systems is proved when the union of all perturbed random attractors is precompact with probability one.

Center manifolds for random dynamical systems with generalized trichotomies

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
In this paper, we consider small perturbations of linear Random Dynamical Systems evolving on a Banach space and admitting a general form of trichotomy.

Learning dynamical systems with hit-and-run random feature maps

open access: yesNature Communications
We show how random feature maps can be used to forecast dynamical systems with excellent forecasting skill. We consider the tanh activation function and judiciously choose the internal weights in a data-driven manner such that the resulting features ...
