Population rate of quantum states and the reverse of the arrow of time
Nova Scientia, 2022 Recently it has been pointed out that an outstanding application of an IBM quantum computer is to reverse the arrow of time (Lesovik et al., 2019). It is explored such a possibility in a two qubits system coupled to a common structured reservoir at zero

String theory and the arrow of time
Journal of High Energy Physics, 2021 Time-like linear dilaton triggers, at the classical level, the creation of closed folded strings at an instant. We show that in cosmology these instant folded strings induce negative pressure at no energy cost.

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.

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.

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 ...

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 ...

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 ...

Identification of a Gravitational Arrow of Time [PDF]
Physical Review Letters, 2014 It is widely believed that special initial conditions must be imposed on any time-symmetric law if its solutions are to exhibit behavior of any kind that defines an `arrow of time'. We show that this is not so. The simplest non-trivial time-symmetric law that can be used to model a dynamically closed universe is the Newtonian $N$-body problem with ...
