Initial correlations in open quantum systems: constructing linear dynamical maps and master equations

open access: yesNew Journal of Physics, 2022
We investigate the dynamics of open quantum systems which are initially correlated with their environment. The strategy of our approach is to analyze how given, fixed initial correlations modify the evolution of the open system with respect to the ...

On the structure of time-delay embedding in linear models of non-linear dynamical systems. [PDF]

open access: yesChaos, 2019
This work addresses fundamental issues related to the structure and conditioning of linear time-delayed models of non-linear dynamics on an attractor.

Modern Koopman Theory for Dynamical Systems [PDF]

open access: yesSIAM Review, 2021
The field of dynamical systems is being transformed by the mathematical tools and algorithms emerging from modern computing and data science. First-principles derivations and asymptotic reductions are giving way to data-driven approaches that formulate ...

Linear Dynamical Systems [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
We consider a probability measure m m on a Hilbert space X X and a bounded linear transformation on X X that preserves the measure. We characterize the linear dynamical systems ( X , m , T ) (X,m,T) for the cases where either

Linear embedding of nonlinear dynamical systems and prospects for efficient quantum algorithms [PDF]

open access: yesPhysics of Plasmas, 2020
The simulation of large nonlinear dynamical systems, including systems generated by discretization of hyperbolic partial differential equations, can be computationally demanding.

Application of the dynamical damper in a piecewise linear system

open access: yesLietuvos Matematikos Rinkinys, 2002

Identification of linear dynamic systems

open access: yesInformation and Control, 1964
A real time computational method is presented for the identification of linear discrete dynamic systems with unknown parameters. It is shown that the method is globally convergent to the true parameters in a stochastic environment. Experimental simulation of 2nd and 4th order systems further affirms the practicality of the method.

On-Line Learning of Linear Dynamical Systems: Exponential Forgetting in Kalman Filters [PDF]

open access: yesAAAI Conference on Artificial Intelligence, 2018
The Kalman filter is a key tool for time-series forecasting and analysis. We show that the dependence of a prediction of Kalman filter on the past is decaying exponentially, whenever the process noise is non-degenerate.

Linear Dynamical Systems

open access: yesIrish Mathematical Society Bulletin, 2020
This expository survey is dedicated to recent developments in the area of linear dynamics. Topics include frequent hypercyclicity, $\mathcal{U}$-frequent hypercyclicity, reiterative hypercyclicity, operators of C-type, Li-Yorke and distributional chaos, and hypercyclic algebras.

A Game—Theoretic Model for a Stochastic Linear Quadratic Tracking Problem

open access: yesAxioms, 2023
In this paper, we solve a stochastic linear quadratic tracking problem. The controlled dynamical system is modeled by a system of linear Itô differential equations subject to jump Markov perturbations.
