System–environment correlations and non-Markovian dynamics [PDF]

open access: yesJournal of Physics B: Atomic, Molecular and Optical Physics, 2012
We determine the total state dynamics of a dephasing open quantum system using the standard environment of harmonic oscillators. Of particular interest are random unitary approaches to the same reduced dynamics and system-environment correlations in the full model.

NON-MARKOVIAN DYNAMICS OF SYSTEM-RESERVOIR ENTANGLEMENT [PDF]

open access: yesInternational Journal of Quantum Information, 2011
Using an exact approach, we study the dynamics of entanglement between two qubits coupled to independent reservoirs and between the two, initially disentangled, reservoirs. We also describe the transfer of bipartite entanglement from the two qubits to their respective reservoirs focussing on the case of two atoms inside two different leaky cavities ...

Quantum dynamics in a tiered non-Markovian environment

open access: yes, 2015
We introduce a new analytical method for studying the open quantum systems problem of a discrete system weakly coupled to an environment of harmonic oscillators.

Robust normalization and guaranteed cost control for a class of uncertain singular Markovian jump systems via hybrid impulsive control [PDF]

open access: yes, 2013
This paper investigates the problem of robust normalization and guaranteed cost control for a class of uncertain singular Markovian jump systems. The uncertainties exhibit in both system matrices and transition rate matrix of the Markovian chain.

Non-Markovian persistence and nonequilibrium critical dynamics [PDF]

open access: yesPhysical Review E, 1997
The persistence exponent θfor the global order parameter, M(t), of a system quenched from the disordered phase to its critical point describes the probability, p(t) \sim t^{-θ}, that M(t) does not change sign in the time interval t following the quench.

Exact Markovian and non-Markovian time dynamics in waveguide QED: collective interactions, bound states in continuum, superradiance and subradiance [PDF]

open access: yesQuantum, 2019
We develop a formalism for modelling $exact$ time dynamics in waveguide quantum electrodynamics (QED) using the real-space approach. The formalism does not assume any specific configuration of emitters and allows the study of Markovian dynamics $\textit ...

Constructing Non-Markovian Decision Process via History Aggregator

open access: yesApplied Sciences
In the domain of algorithmic decision-making, non-Markovian dynamics manifest as a significant impediment, especially for paradigms such as Reinforcement Learning (RL), thereby exerting far-reaching consequences on the advancement and effectiveness of ...

Quantum process identification: a method for characterizing non-markovian quantum dynamics

open access: yesNew Journal of Physics, 2019
Established methods for characterizing quantum information processes do not capture non-Markovian (history-dependent) behaviors that occur in real systems.

Geometric Signature of Non-Markovian Dynamics

open access: yesAnnals of Physics
Non-Markovian effects in the dynamics of an open system are typically characterized by non-monotonic information flows from the system to its environment or by information backflows from the environment to the system. Using a two-level system (TLS) coupled to a dissipative single-mode cavity, we demonstrate that the geometric decoherence of the open ...
