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.

A Computer's Arrow of Time [PDF]

open access: yesEntropy, 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.

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

open access: yesNeuroImage: 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 ...

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.

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.

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

open access: yesEntropy
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

Modeling the Arrows of Time with Causal Multibaker Maps

open access: yesEntropy
Why do we remember the past, and plan the future? We introduce a toy model in which to investigate emergent time asymmetries: the causal multibaker maps. These are reversible discrete-time dynamical systems with configurable causal interactions. Imposing

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

open access: yesNova 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

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.
