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.

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.

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.

The Astrophysical Journal, 1976 A model of the universe which resolves the apparent contradiction between the historical and the thermodynamic arrows of time is presented. Both arrows are reconciled with the almost time-symmetric character of physical laws at the microscopic level. The theory implies that the universe is unfolding in time but not unraveling. (BJG)

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.

A note on singularities and the arrow of time [PDF]
Serbian Astronomical Journal, 2000 An interesting thought experiment claiming to highlight the connection between singularities and the global arrow of time is re-analyzed, and a further specification suggested.

Entropy, 2012 Quantum gravity, the initial low entropy state of the Universe, and the problem of time are interlocking puzzles. In this article, we address the origin of the arrow of time from a cosmological perspective motivated by a novel approach to quantum ...

Fluctuation, Dissipation and the Arrow of Time [PDF]
Entropy, 2011 The recent development of the theory of fluctuation relations has led to new insights into the ever-lasting question of how irreversible behavior emerges from time-reversal symmetric microscopic dynamics.

Discrete & Continuous Dynamical Systems - S, 2010 We believe the following three ingredients are enough to explain the mystery of the arrow of time: (1). equations of dynamics of gas molecules, (2). chaotic instabilities of the equations of dynamics, (3). unavoidable perturbations to the gas molecules. The level of physical rigor or mathematical rigor that can be reached for such a theory is unclear.
