Non-Markovian Optimal Prediction [PDF]

open access: yesmcma, 2001
Optimal prediction methods compensate for a lack of resolution in the numerical solution of complex problems through the use of prior statistical information. We know from previous work that in the presence of strong underresolution a good approximation needs a non-Markovian "memory", determined by an equation for the "orthogonal", i.e., unresolved ...

Non-Markovian Quantum Probes [PDF]

open access: yesOpen Systems & Information Dynamics, 2014
We review the most recent developments in the theory of open quantum systems focusing on situations in which the reservoir memory effects, due to long-lasting and non-negligible correlations between system and environment, play a crucial role. These systems are often referred to as non-Markovian systems.

Non-Markovian Stochastic Resonance [PDF]

open access: yesPhysical Review Letters, 2003
The phenomenological linear response theory of non-Markovian Stochastic Resonance (SR) is put forward for stationary two-state renewal processes. In terms of a derivation of a non-Markov regression theorem we evaluate the characteristic SR-quantifiers; i.e. the spectral power amplification (SPA) and the signal-to-noise ratio (SNR), respectively.

Non-Markovian Quantum Thermometry

open access: yesPhysical Review Applied, 2022
The rapidly developing quantum technologies and thermodynamics have put forward a requirement to precisely control and measure the temperature of microscopic matter at the quantum level. Many quantum thermometry schemes have been proposed. However, precisely measuring low temperature is still challenging because the obtained sensing errors generally ...

Noise-induced non-Markovianity [PDF]

open access: yesPhysical Review A, 2018
We have studied the non-Markovianity of dichotomously driven spin-boson model in the strong coupling regime in both memory kernel and time convolutionless master equation formulations. A strong correlation between the decay time of the environmental correlation function and the non-zero non-Markovianity is found in the absence of the external noise ...

Page curve from non-Markovianity

open access: yesJournal of High Energy Physics, 2021
In this paper, we use the exactly solvable Sachdev-Ye-Kitaev model to address the issue of entropy dynamics when an interacting quantum system is coupled to a non-Markovian environment.

Reinforcement Learning in Non-Markovian Environments

open access: yesSSRN Electronic Journal, 2022
Motivated by the novel paradigm developed by Van Roy and coauthors for reinforcement learning in arbitrary non-Markovian environments, we propose a related formulation and explicitly pin down the error caused by non-Markovianity of observations when the Q-learning algorithm is applied on this formulation.
