Thermodynamics of Accelerating Black Holes. [PDF]

Physical Review Letters, 2016
We address a long-standing problem of describing the thermodynamics of an accelerating black hole. We derive a standard first law of black hole thermodynamics, with the usual identification of entropy proportional to the area of the event horizon-even ...

Black hole horizons can hide positive heat capacity

Physics Letters B, 2018
Regarding the volume as independent thermodynamic variable we point out that black hole horizons can hide positive heat capacity and specific heat. Such horizons are mechanically marginal, but thermally stable.

Thermodynamical behaviour of the Variable Chaplygin gas

, 2015
The thermodynamical behaviour of the Variable Chaplygin gas (VCG) model is studied, using an equation of state like $P = - \frac{B}{\rho}$, where $B = B_{0}V^{-\frac{n}{3}}$.

Hydrodynamics and the fluctuation theorem

, 2011
The fluctuation theorem is a pivotal result of statistical physics. It quantifies the probability of observing fluctuations which are in violation of the second law of thermodynamics.

Thermodynamic signatures of edge states in topological insulators

, 2016
Topological insulators are states of matter distinguished by the presence of symmetry protected metallic boundary states. These edge modes have been characterised in terms of transport and spectroscopic measurements, but a thermodynamic description has ...

Studying The Characteristic Parameters and External Freedom Degree of Polyethylene in different Molecular Weights By Hole Theory

Tikrit Journal of Pure Science, 2020
The external degree of freedom of linear and branched molecules of polymers played an important role in new polymer synthesis. The theory Simha-Somcynsky (SS) which established for the first time the statistical thermodynamics and polymers state of ...

Volume and topological invariants of quantum many-body systems

Physical Review Research, 2020
Quantum many-body systems described by Lagrangian path integrals can realize many different topological phases of matter. One of the most important problems in condensed-matter physics is to extract topological invariants from the Lagrangian and to ...

Holographic thermodynamics of a five-dimensional neutral Gauss–Bonnet AdS black hole

European Physical Journal C: Particles and Fields
Motivated by the recent progress on the holographic dual of the extended thermodynamics for black holes in anti-de Sitter (AdS) space, we investigate the holographic thermodynamics for the five-dimensional neutral Gauss–Bonnet AdS black hole in the ...

Viral genome structures are optimal for capsid assembly

eLife, 2013
Understanding how virus capsids assemble around their nucleic acid (NA) genomes could promote efforts to block viral propagation or to reengineer capsids for gene therapy applications.
