Experimental Heat-Bath Cooling of Spins [PDF]

open access: yes, 2014
Algorithmic cooling (AC) is a method to purify quantum systems, such as ensembles of nuclear spins, or cold atoms in an optical lattice. When applied to spins, AC produces ensembles of highly polarized spins, which enhance the signal strength in nuclear ...

Entropy-stable schemes in the low-Mach-number regime: Flux-preconditioning, entropy breakdowns, and entropy transfers [PDF]

open access: yesJournal of Computational Physics, 2022
Entropy-Stable (ES) schemes, specifically those built from [Tadmor \textit{Math. Comput.} 49 (1987) 91], have been gaining interest over the past decade, especially in the context of under-resolved simulations of compressible turbulent flows using high-order methods.

Breakdown of local information processing may underlie isoflurane anesthesia effects.

open access: yesPLoS Computational Biology, 2017
The disruption of coupling between brain areas has been suggested as the mechanism underlying loss of consciousness in anesthesia. This hypothesis has been tested previously by measuring the information transfer between brain areas, and by taking reduced

Local information transfer as a spatiotemporal filter for complex systems

open access: yes, 2008
We present a measure of local information transfer, derived from an existing averaged information-theoretical measure, namely transfer entropy. Local transfer entropy is used to produce profiles of the information transfer into each spatiotemporal point ...

Analysis of entropy production in some enclosed subsystems where spontaneous processes take place [PDF]

open access: yesINCAS Bulletin, 2016
It is well-known that every spontaneous process occurring in an isolated system is accompanied by increasing entropy. The goal of this paper is to show that if the system is made of several subsystems, the entropy production of some subsystems can be ...

Causality Analysis with Different Probabilistic Distributions Using Transfer Entropy

open access: yesApplied Sciences, 2023
This paper presents the results of an analysis of causality detection in a multi-loop control system. The investigation focuses on application of the Transfer Entropy method, which is not commonly used during the exact construction of information and ...

Efficacy of applying discontinuous boundary condition on the heat transfer and entropy generation through a slip microchannel equipped with nanofluid

open access: yesEngineering Applications of Computational Fluid Mechanics, 2022
In this study, the laminar nanofluid flow in the microchannel with a discontinuous-boundary condition was investigated. Considering the slip condition, heat transfer and entropy generation were studied.

Information Theory Analysis of Cascading Process in a Synthetic Model of Fluid Turbulence

open access: yesEntropy, 2014
The use of transfer entropy has proven to be helpful in detecting which is the verse of dynamical driving in the interaction of two processes, X and Y .

Exact Entanglement dynamics in Three Interacting Qubits

open access: yes, 2019
Motivated by recent experimental study on coherent dynamics transfer in three interacting atoms or electron spins \cite{Barredo:2015,Rosenfeld:2018}, here we study entanglement entropy transfer in three interacting qubits.
