Algebraical Entropy and Arrow of Time [PDF]

Entropy, 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.

Supernovae and the Arrow of Time [PDF]

Entropy, 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.

A Computer's Arrow of Time [PDF]

Entropy, 2005
: Some researchers believe that the psychological or consciousness arrow of time is a consequence of the thermodynamic arrow. Some don't. As for many issues in this area, the disagreement revolves about fundamental and undebatable assumptions.

A Lenient Causal Arrow of Time? [PDF]

Entropy, 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.

The arrow of time in Parkinson’s disease [PDF]

NeuroImage: Clinical
Background: Parkinson’s disease (PD) is a system-level disorder that implicates brain network dynamics across multiple scales. Detecting the ‘arrow of time’, or temporal reversibility of the brain’s information processing flow enables quantification of ...

Arrow of Time in Quantum Mechanics and Set Theory [PDF]

Entropy
The set-theory twist of quantum mechanics uncovers forcing in axiomatic Zermelo–Fraenkel set theory as a viable tool to understand the singularities in a physical spacetime and serves as a link between the quantum and classical worlds. The random forcing

Population rate of quantum states and the reverse of the arrow of time

Nova Scientia, 2022
Recently it has been pointed out that an outstanding application of an IBM quantum computer is to reverse the arrow of time (Lesovik et al., 2019). It is explored such a possibility in a two qubits system coupled to a common structured reservoir at zero

String theory and the arrow of time

Journal 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.

Length of Time’s Arrow

Physical Review Letters, 2008
An unresolved problem in physics is how the thermodynamic arrow of time arises from an underlying time reversible dynamics. We contribute to this issue by developing a measure of time-symmetry breaking, and by using the work fluctuation relations, we determine the time asymmetry of recent single molecule RNA unfolding experiments.

The Contractual Cryptoeconomy: An Arrow of Time for Economics

The Journal of The British Blockchain Association, 2019
We consider the potential blockchains have for building a framework for all manner of contracts that can characterize an economy using the unifying idea of control over their duration. Such a contractual cryptoeconomy (CCE)
