Memory Systems, the Epistemic Arrow of Time, and the Second Law [PDF]
The epistemic arrow of time is the fact that our knowledge of the past seems to be both of a different kind and more detailed than our knowledge of the future. Just like with the other arrows of time, it has often been speculated that the epistemic arrow

Gravitational Entropy and the Second Law of Thermodynamics [PDF]
The spontaneous violation of Lorentz and diffeomorphism invariance in a phase near the big bang lowers the entropy, allowing for an arrow of time and the second law of thermodynamics. The spontaneous symmetry breaking leads to

Temporal Asymmetry, Entropic Irreversibility, and Finite-Time Thermodynamics: From Parmenides–Einstein Time-Reversal Symmetry to the Heraclitan Entropic Arrow of Time [PDF]
In this paper, we combine the two universalisms of thermodynamics and dynamical systems theory to develop a dynamical system formalism for classical thermodynamics. Specifically, using a compartmental dynamical system energy flow model we develop a state-

Using the Klauder enhanced quantization to specify the cosmological constant as a baseline for the mass of a graviton, we eventually develop with an initial degrees of freedom argument of about 1000, instead of 100 or so, implying no quantum fluctuations

Pre-bangian origin of our entropy and time arrow [PDF]
I argue that, in the chaotic version of string cosmology proposed recently, classical and quantum effects generate, at the time of exit to radiation, the correct amount of entropy to saturate a Hubble (or holography) entropy bound (HEB) and to identify ...

Is the hypothesis about a low entropy initial state of the Universe necessary for explaining the arrow of time? [PDF]
According to statistical mechanics, micro-states of an isolated physical system (say, a gas in a box) at time t0 in a given macro-state of less-than-maximal entropy typically evolve in such a way that the entropy at time t increases with jt t0j in both ...

Entropy, biological evolution and the psychological arrow of time [PDF]
We argue that in Universes where future and past differ only by the entropy content a psychological arrow of time pointing in the direction of entropy increase can arise from natural selection in biological evolution.

Pre-Big-Bang Black-Hole Remnants and Past Low Entropy
Dark matter could be composed by black-hole remnants formed before the big-bang era in a bouncing cosmology. This hypothetical scenario has implications on the issue of the arrow of time: it upsets a common attribution of past low entropy to the state of
