Journal of Physics: Conference Series, 2019 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

Entropy, biological evolution and the psychological arrow of time [PDF]
, 2014 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.

Entropy, Biological Evolution and the Psychological Arrow of Time
Journal of Modern Physics, 2016 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. We show that this effect can be demonstrated in very simple toy computer simulations of evolution in an entropy increasing or decreasing

Two Types of Temporal Symmetry in the Laws of Nature [PDF]
EntropyThis work explores the implications of assuming time symmetry and applying bridge-type, time-symmetric temporal boundary conditions to deterministic laws of nature with random components.

Pre-Big-Bang Black-Hole Remnants and Past Low Entropy
Universe, 2018 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

Comment on "Entropy production and the arrow of time"
, 2007 J.M.R. Parrondo at al. in arXiv:0904.1573 continue numerous efforts to unify the concepts of the arrow of time and entropy production with the concept of time invariance in physics. This is a wrong way.

The Maximum Entropy Principle in the Absence of a Time-Arrow: Fractional-Pole Models [PDF]
IEEE Transactions on Information Theory, 2007 The maximum entropy (ME) principle, as it is often invoked in the context of time-series analysis, suggests the selection of a power spectrum which is consistent with autocorrelation data and corresponds to a random process least predictable from past observations. We introduce and compare a class of spectra with the property that the underlying random

Entropy production in systems with unidirectional transitions
Physical Review Research, 2020 The entropy production is one of the most essential features for systems operating out of equilibrium. The formulation for discrete-state systems goes back to the celebrated Schnakenberg's work and hitherto can be carried out when for each transition ...

Entropy Maximization, Time Emergence, and Phase Transition [PDF]
EntropyWe survey developments in the use of entropy maximization for applying the Gibbs Canonical Ensemble to finite situations. Biological insights are invoked along with physical considerations.

Entropy Production and Thermodynamic Arrow of Time in a Recollapsing Universe
, 1999 We investigate the thermodynamic arrow of time in a time-symmetrically recollapsing universe by calculating quantum mechanically the entropy production of a massive scalar field. It is found that even though the Hamiltonian has a time-reversal symmetry with respect to the maximum expansion of the universe, the entropy production is generic and the ...
