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.

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.

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.

Opposite Thermodynamic Arrows of Time [PDF]
Phys.Rev.Lett. 83 (1999) 5419-5422, 1999 A model in which two weakly coupled systems maintain opposite running thermodynamic arrows of time is exhibited. Each experiences its own retarded electromagnetic interaction and can be seen by the other. The possibility of opposite-arrow systems at stellar distances is explored and a relation to dark matter suggested.

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 compromised arrow of time [PDF]
arXiv, 2000 The second law of thermodynamics - the usual statement of the arrow of time - has been called the most fundamental law of physics. It is thus difficult to conceive that a single dynamical system could contain subsystems, in significant mutual contact, possessing opposite thermodynamic arrows of time.

The Global Nature of the Arrow of Time and the Bohm-Reichenbach diagram [PDF]
arXiv, 2000 The importance of the global nature of the arrow of time is shown. Classical Reichenbach diagram and quantum Bohm-Reichenbach diagram, for the universe are introduced. They are used to show the increase of entropy in closed systems, the global nature of the quantum measurement, and the relation among the different arrows of time.
