Quantum measurement arrow of time and fluctuation relations for measuring spin of ultracold atoms. [PDF]

open access: yesNat Commun, 2021
The origin of macroscopic irreversibility from microscopically time-reversible dynamical laws—often called the arrow-of-time problem—is of fundamental interest in both science and philosophy.

A Lenient Causal Arrow of Time? [PDF]

open access: yesEntropy, 2018
One of the basic assumptions underlying Bell’s theorem is the causal arrow of time, having to do with temporal order rather than spatial separation.

Time-Reversal Symmetry and Arrow of Time in Quantum Mechanics of Open Systems [PDF]

open access: yesEntropy, 2019
It is one of the most important and long-standing issues of physics to derive the irreversibility out of a time-reversal symmetric equation of motion. The present paper considers the breaking of the time-reversal symmetry in open quantum systems and the ...

The arrow of time of brain signals in cognition: Potential intriguing role of parts of the default mode network. [PDF]

open access: yesNetw Neurosci, 2023
A promising idea in human cognitive neuroscience is that the default mode network (DMN) is responsible for coordinating the recruitment and scheduling of networks for computing and solving task-specific cognitive problems.

Decomposing the Local Arrow of Time in Interacting Systems. [PDF]

open access: yesPhys Rev Lett, 2022
We show that the evidence for a local arrow of time, which is equivalent to the entropy production in thermodynamic systems, can be decomposed. In a system with many degrees of freedom, there is a term that arises from the irreversible dynamics of the ...

Algebraical Entropy and Arrow of Time [PDF]

open access: yesEntropy, 2022
Usually, it is supposed that irreversibility of time appears only in macrophysics. Here, we attempt to introduce the microphysical arrow of time assuming that at a fundamental level nature could be non-associative.

Arrow of Time, Entropy, and Protein Folding: Holistic View on Biochirality. [PDF]

open access: yesInt J Mol Sci, 2022
Chirality is a universal phenomenon, embracing the space–time domains of non-organic and organic nature. The biological time arrow, evident in the aging of proteins and organisms, should be linked to the prevalent biomolecular chirality.

Supernovae and the Arrow of Time [PDF]

open access: yesEntropy, 2022
Supernovae are explosions of stars and are a central problem in astrophysics. Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) instabilities develop during the star’s explosion and lead to intense interfacial RT/RM mixing of the star materials.

String theory and the arrow of time [PDF]

open access: yesJournal of High Energy Physics, 2021
Time-like linear dilaton triggers, at the classical level, the creation of closed folded strings at an instant. We show that in cosmology these instant folded strings induce negative pressure at no energy cost.

The arrow of time: Advancing insights into action control from the arrow version of the Eriksen flanker task. [PDF]

open access: yesAtten Percept Psychophys, 2021
Since its introduction by B. A. Eriksen and C. W. Eriksen (Perception & Psychophysics, 16, 143–49, 1974), the flanker task has emerged as one of the most important experimental tasks in the history of cognitive psychology.
