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.

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)

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.

Seeing the Arrow of Time [PDF]
2014 IEEE Conference on Computer Vision and Pattern Recognition, 2014 We explore whether we can observe Time's Arrow in a temporal sequence -- is it possible to tell whether a video is running forwards or backwards? We investigate this somewhat philosophical question using computer vision and machine learning techniques. We explore three methods by which we might detect Time's Arrow in video sequences, based on distinct ...

Alternative interpretation of relativistic time-reversal and the time arrow
Physical Review Research, 2022 It is well known that the 4-rotation in four-dimensional space-time is equivalent to the CPT transformation (C is the charge conjugation, P is the space inversion, and T is the time reversal). The standard definition of the T reversal includes the change

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 ...

Wormholes and the thermodynamic arrow of time
Physical Review Research, 2020 In classical thermodynamics, heat cannot spontaneously pass from a colder system to a hotter system, which is called the thermodynamic arrow of time. However, if the initial states are entangled, the direction of the thermodynamic arrow of time may not ...

The arrow of time in operational formulations of quantum theory [PDF]
Quantum, 2021 The operational formulations of quantum theory are drastically time oriented. However, to the best of our knowledge, microscopic physics is time-symmetric.
