Calibration of Local Chiralities and Time-Arrows Based on Quantum Nonlocality [PDF]
arXiv, 2000 Unlike classical physics, quantum mechnanics is sensitive to mistaken choice of chiralities or time-arrows of local reference systems. Quantum correlations between distant electron spins, for instance, would reveal a mistaken local chirality. Local polarization measurements and classical communication enable the distant partners to compare their local ...

A note on singularities and the arrow of time [PDF]
Serbian Astronomical Journal, 2000 An interesting thought experiment claiming to highlight the connection between singularities and the global arrow of time is re-analyzed, and a further specification suggested.

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 ...

Discrete & Continuous Dynamical Systems - S, 2010 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.

Time, the Arrow of Time, and Quantum Mechanics [PDF]
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.

Quantum Computation and Arrows of Time [PDF]
Entropy, 2020 Quantum physics is surprising in many ways. One surprise is the threat to locality implied by Bell’s Theorem. Another surprise is the capacity of quantum computation, which poses a threat to the complexity-theoretic Church-Turing thesis.

Time-Reversal Symmetry and Arrow of Time in Quantum Mechanics of Open Systems [PDF]
Entropy, 2019 It is one of the most important and long-standing issues of physics to derive the irreversibility out of a time-reversal symmetric equation of motion. The present paper considers the breaking of the time-reversal symmetry in open quantum systems and the ...

Small and Simple Systems That Favor the Arrow of Time [PDF]
EntropyThe 2nd law of thermodynamics yields an irreversible increase in entropy until thermal equilibrium is achieved. This irreversible increase is often assumed to require large and complex systems to emerge from the reversible microscopic laws of physics. We

Emergence of opposing arrows of time in open quantum systems [PDF]
Scientific ReportsDeriving an arrow of time from time-reversal symmetric microscopic dynamics is a fundamental open problem in many areas of physics, ranging from cosmology, to particle physics, to thermodynamics and statistical mechanics.
