Work fluctuation, entropy, and time’s arrow in time-asymmetric engine cycles
Journal of Physics A: Mathematical and Theoretical, 2020Abstract We derive a thermodynamic uncertainty relation that governs the work yield and the entropy production of an engine operating with a time-asymmetric cycle such as the Carnot cycle. The relation shows an intercorrelation between one engine cycle and its time-reversed cycle, disclosing the role of the time-asymmetry of an engine

Fractals, Entropy and the Arrow of Time
2016Why can we not move backward in time? According to Relativity, time is just one more dimension like length, width and height where we can go as easily backward as forward. What makes time special? Newton’s laws are symmetric in time and so is even Schrodinger’s equation which controls the happenings at the quantum level.

The Arrow of Time, Entropy and the Expansion of the Universe
1976Setting aside the guidance of consciousness, we discover a signpost for time in the physical world itself. The signpost is a rather peculiar one, and I would not venture to say that the discovery of the signpost amounts to the same thing as the discovery of an objective ‘going on of time’ in the universe.

Vacuum Radiation, Entropy and the Arrow Of Time
2002The root mean square perturbations on particles produced by vacuum radiation must be limited by the uncertainty principle, i.e., 1/2 1/2 =ħ/2, where 1/2 and 1/2 are the root mean square values of drift in spatial and momentum coordinates. The value 1/2 =(ħt/m) 1/2 , where m is the mass of the particle, can be obtained both from classical SED ...

From Randomness and Entropy to the Arrow of Time
The Element reconstructs, analyses and compares different derivational routes to a grounding of the Arrow of Time in entropy. It also evaluates the link between entropy and visible disorder, and the related claim of an alignment of the Arrow of Time with a development from order to visible disorder.openaire +2 more sources
Macroscopic laws, microscopic dynamics, time's arrow and Boltzmann's entropy
Physica A: Statistical Mechanics and its Applications, 1993Abstract I discuss Boltzmann's resolution of the apparent paradox: microscopic dynamics are time-symmetric but the behavior of macroscopic objects, composed of microscopic constituents, is time-asymmetric. Noting the great disparity between macroscales and microscales Boltzmann developed a statistical approach which explains the observed macroscopic ...
