Gravitational Entropy and Inflation
Entropy, 2013 The main topic of this paper is a description of the generation of entropy at the end of the inflationary era. As a generalization of the present standard model of the Universe dominated by pressureless dust and a Lorentz invariant vacuum energy (LIVE ...

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 ...

How many universes are necessary for an ice cream to melt? [PDF]
Serbian Astronomical Journal, 2003 We investigate a quantitative consequence of the Acausal-Anthropic approach to solving the long-standing puzzle of the thermo dynamical arrow of time.

Irreversibility of time in general relativity [PDF]
Известия Саратовского университета. Новая серия Серия: Физика, 2022 Background and Objectives: The equations of classical dynamics of particles and waves admit solutions with the reverse flow of time. Therefore, it is generally assumed that classical dynamics does not reflect the irreversibility of time.

Does a computer have an arrow of time? [PDF]
, 2007 In [Sch05a], it is argued that Boltzmann's intuition, that the psychological arrow of time is necessarily aligned with the thermodynamic arrow, is correct.

Decomposing the Local Arrow of Time in the Brain
Physics, 2022 A broken egg cannot spontaneously unbreak, and a drop of ink once mixed in water cannot spontaneously unmix. Nature is full of such irreversible phenomena, actions that cannot undo themselves.

Maxwell’s Demon in Quantum Mechanics
Entropy, 2020 Maxwell’s Demon is a thought experiment devised by J. C. Maxwell in 1867 in order to show that the Second Law of thermodynamics is not universal, since it has a counter-example. Since the Second Law is taken by many to provide an arrow of time, the

Energies, 2022 Based on the square heat-generation body (HGB) with “arrow-shaped” high-thermal-conductivity channel (HTCC) model established in the previous literature, we performed multi-objective optimization (MOO) with maximum temperature difference (MTD ...

Fluctuation, Dissipation and the Arrow of Time [PDF]
, 2011 The recent development of the theory of fluctuation relations has led to new insights into the ever-lasting question of how irreversible behavior emerges from time-reversal symmetric microscopic dynamics.
