On a new definition of quantum entropy
, 2008 It is proved here that, as a consequence of the unitary quantum evolution, the expectation value of a properly defined quantum entropy operator (as opposed to the non-evolving von Neumann entropy) can only increase during non adiabatic transformations ...

Nuclear Physics B, 2014 We investigate the holographic entanglement entropy in the metal/superconductor phase transition for the Born–Infeld electrodynamics with full backreaction and note that the entropy is a good probe to study the properties of the phase transition. For the

Entropy of gravitationally collapsing matter in FRW universe models
, 2005 We look at a gas of dust and investigate how its entropy evolves with time under a spherically symmetric gravitational collapse. We treat the problem perturbatively and find that the classical thermodynamic entropy does actually increase to first order ...

Entropy increase as a consequence of measure invariance [PDF]
Proceedings of the American Mathematical Society, 1985 Summary: An inequality, used in statistical mechanics for proving that entropy does not decrease, is shown to hold for general \(\sigma\)-finite measure spaces. We comment briefly on the corresponding Hilbert space result.

Generic increase of observational entropy in isolated systems
Physical Review ResearchObservational entropy—a quantity that unifies Boltzmann's entropy, Gibbs' entropy, von Neumann's macroscopic entropy, and the diagonal entropy—was recently argued to play a key role in a modern formulation of statistical mechanics.

Fluctuation Theorem for Hidden Entropy Production
, 2012 In the general process of eliminating dynamic variables in Markovian models, there exists a difference in the irreversible entropy production between the original and reduced dynamics. We call this difference the hidden entropy production, since it is an

, 2016 Dan Rudolph showed that for an amenable group $\Gamma$, the generic measure-preserving action of $\Gamma$ on a Lebesgue space has zero entropy. Here this is extended to nonamenable groups.

, 2009 Biological macromolecules, proteins and nucleic acids are composed exclusively of chirally pure monomers. The chirality consensus appears vital for life and it has even been considered as a prerequisite of life.

Entanglement of Solitons in the Frenkel-Kontorova Model
, 2008 We investigate entanglement of solitons in the continuum-limit of the nonlinear Frenkel-Kontorova chain. We find that the entanglement of solitons manifests particle-like behavior as they are characterized by localization of entanglement. The von-Neumann
