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

open access: yesFrontiers 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]

open access: yesEntropy, 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]

open access: yesEntropy, 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 ...

Population rate of quantum states and the reverse of the arrow of time

open access: yesNova 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

open access: yesJournal 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

open access: yesInformation, 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

open access: yesThe 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)

Seeing the Arrow of Time [PDF]

open access: yes2014 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 ...

Interventionism in Statistical Mechanics

open access: yesEntropy, 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.
