The length of time's arrow [PDF]
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 ...

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 gravitation.

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 ...

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

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 ...

Epistemological Suggestions in „Entropy Low and Economic Process” [PDF]
Theoretical and Applied Economics, 2006 The paper is aimed to derive, on criticism basis (following, especially, the critic rationalism, as method), epistemological suggestions from the crucial work of Nicholas Georgescu-Roegen, “The Entropy Law and the Economic Process”, in order to these ...

Remarks on the Compatibility of Opposite Arrows of Time II
Entropy, 2006 In a series of papers [1,2,3], Lawrence Schulman presented examples which demonstrate the compatibility of opposite arrows of time in various situations.

The Importance of Boundary Conditions in Quantum Mechanics [PDF]
, 2003 We discuss the role of boundary conditions in determining the physical content of the solutions of the Schrodinger equation. We study the standing-wave, the ``in,'' the ``out,'' and the purely outgoing boundary conditions. As well, we rephrase Feynman's $

Changing the load of a arrow crane while carrying out loading and unloading works [PDF]
Научно-технический вестник Брянского государственного университета, 2020 The stability of self-propelled jib cranes is a key task in the process of their operation. The developed calculation scheme of the arrow self-propelled crane and the restrictions imposed on its movement in time and space, allowed to obtain mathematical ...

Entanglement and the Thermodynamic Arrow of Time [PDF]
, 2010 We discuss quantum entanglement in the context of the thermodynamic arrow of time. We review the role of correlations in entropy-decreasing events and prove that the occurrence of a transformation between two thermodynamic states constitutes a new type ...
