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 and Continuous Dynamical Systems - S, 2014 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.

Interventionism in Statistical Mechanics
Entropy, 2012 I defend the idea that the fact that no system is entirely isolated (“Interventionism”) can be used to explain the successful use of the microcanonical distribution in statistical mechanics.

Discovering the Arrow of Time in Machine Learning
Information, 2021 Machine learning (ML) is increasingly useful as data grow in volume and accessibility. ML can perform tasks (e.g., categorisation, decision making, anomaly detection, etc.) through experience and without explicit instruction, even when the data are too ...

The Contractual Cryptoeconomy: An Arrow of Time for Economics
The Journal of The British Blockchain Association, 2019 We consider the potential blockchains have for building a framework for all manner of contracts that can characterize an economy using the unifying idea of control over their duration. Such a contractual cryptoeconomy (CCE)

Time, the Arrow of Time, and Quantum Mechanics
Frontiers in Physics, 2018 It is brought forward that viable theories of the physical world that have no variable at all that can play the role of time, do not exist; some notion of time is one of the very first ingredients a candidate theory should possess.

Relating the thermodynamic arrow of time to the causal arrow [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2008 Consider a Hamiltonian system that consists of a slow subsystem S and a fast subsystem F. The autonomous dynamics of S is driven by an effective Hamiltonian, but its thermodynamics is unexpected. We show that a well-defined thermodynamic arrow of time (second law) emerges for S whenever there is a well-defined causal arrow from S to F and the back ...

Physical Review Letters, 2008 An unresolved problem in physics is how the thermodynamic arrow of time arises from an underlying time reversible dynamics. We contribute to this issue by developing a measure of time-symmetry breaking, and by using the work fluctuation relations, we determine the time asymmetry of recent single molecule RNA unfolding experiments.

Gravitational Entropy and Inflation
Entropy, 2013 The main topic of this paper is a description of the generation of entropy at the end of the inflationary era. As a generalization of the present standard model of the Universe dominated by pressureless dust and a Lorentz invariant vacuum energy (LIVE ...
