Fisher's arrow of `time' in cosmological coherent phase space
, 1998 Fisher's arrow of `time' in a cosmological phase space defined as in quantum optics (i.e., whose points are coherent states) is introduced as follows. Assuming that the phase space evolution of the universe starts from an initial squeezed cosmological ...

Irreversibility and the arrow of time in a quenched quantum system [PDF]
, 2015 Irreversibility is one of the most intriguing concepts in physics. While microscopic physical laws are perfectly reversible, macroscopic average behavior has a preferred direction of time. According to the second law of thermodynamics, this arrow of time

Irreversibility as thermodynamic time
Open Physics, 2021 In Newtonian mechanics, time and space are perceived as absolute entities. In Einstein’s relativity theory, time is frame dependent. Time is also affected by gravitational field and as the field varies in space, time also varies throughout space.

The cosmological origin of time-asymmetry [PDF]
Class.Quant.Grav. 20 (2003) 369-392, 2002 In this paper we address the problem of the arrow of time from a cosmological point of view, rejecting the traditional entropic approach that defines the future direction of time as the direction of the entropy increase: from our perspective, the arrow of time has a global origin and it is an intrinsic, geometrical feature of space-time.

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 ...

New Journal of Physics, 2016 We postulate a principle stating that the initial condition of a physical system is typically algorithmically independent of the dynamical law. We discuss the implications of this principle and argue that they link thermodynamics and causal inference. On

Cancer biomarker discovery: the entropic hallmark. [PDF]
PLoS ONE, 2010 BACKGROUND: It is a commonly accepted belief that cancer cells modify their transcriptional state during the progression of the disease. We propose that the progression of cancer cells towards malignant phenotypes can be efficiently tracked using high ...

Quantum Gravity If Non-Locality Is Fundamental
Entropy, 2022 I take non-locality to be the Michelson–Morley experiment of the early 21st century, assume its universal validity, and try to derive its consequences.

The Second Law of Thermodynamics and the Psychological Arrow of Time
British Journal for the Philosophy of Science, 2020 Can the second law of thermodynamics explain our mental experience of the direction of time? According to an influential approach, the past hypothesis of universal low entropy (required to explain the temporal directionality of the second law in terms of

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 ...
