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.

Pre-bangian origin of our entropy and time arrow [PDF]
Physics Letters B, 1999 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, within our own Universe, the arrow of time.

Arrow of Time, Entropy, and Protein Folding: Holistic View on Biochirality [PDF]
International Journal of Molecular Sciences, 2022 Chirality is a universal phenomenon, embracing the space–time domains of non-organic and organic nature. The biological time arrow, evident in the aging of proteins and organisms, should be linked to the prevalent biomolecular chirality. This hypothesis drives our exploration of protein aging, in relation to the biological aging of an organism.

Entropy and the arrow of time in population dynamics
Biosystems, 2022 The concept of entropy in statistical physics is related to the existence of irreversible macroscopic processes. In this work, we explore a recently introduced entropy formula for a class of stochastic processes with more than one absorbing state that is extensively used in population genetics models.

Influence of Thermodynamic Arrow of Time on Entropy
Physical Science International Journal, 2023 This study assessed the influence of thermodynamic arrow of time on entropy for boiled cooling water (physical process), the universe and the air (natural process). This was done by determining the entropies of boiled water, the universe and air. This was achieved by using 1.5 litres of pure water, a 2 liter electric kettle, a digital thermometer, a ...

Entropy Production and Thermodynamic Arrow of Time in a Recollapsing\n Universe [PDF]
, 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 ...

Entropy, Information and Complexity or Which Aims the Arrow of Time? [PDF]
Entropy, 2015 In this article, we analyze the interrelationships among such notions as entropy, information, complexity, order and chaos and show using the theory of categories how to generalize the second law of thermodynamics as a law of increasing generalized ...

Complex Time Approach to the Hamiltonian and the Entropy Production of the Damped Harmonic Oscillator [PDF]
EntropyThe present work applies and extends the previously developed Quantitative Geometrical Thermodynamics (QGT) formalism to the derivation of a Hamiltonian for the damped harmonic oscillator (DHO) across all damping regimes.

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.
