Anomalies, black strings and the charged Cardy formula

Journal of High Energy Physics, 2020
We derive the general anomaly polynomial for a class of two-dimensional CFTs arising as twisted compactifications of a higher-dimensional theory on compact manifolds ℳ d , including the contribution of the isometries of ℳ d .

Uniqueness of near-horizon geometries of rotating extremal AdS(4) black holes [PDF]

, 2009
We consider stationary extremal black hole solutions of the Einstein-Maxwell equations with a negative cosmological constant in four dimensions. We determine all non-static axisymmetric near-horizon geometries (with non-toroidal horizon topology) and all

The universal property of the entropy sum of black holes in all dimensions

Physics Letters B, 2014
It is proposed by Cvetic et al. [1] that the product of all horizon areas for general rotating multi-change black holes has universal expressions independent of the mass.

Thermodynamics of random reaction networks. [PDF]

PLoS ONE, 2015
Reaction networks are useful for analyzing reaction systems occurring in chemistry, systems biology, or Earth system science. Despite the importance of thermodynamic disequilibrium for many of those systems, the general thermodynamic properties of ...

A faster horse on a safer trail: generalized inference for the efficient reconstruction of weighted networks

New Journal of Physics, 2020
Due to the interconnectedness of financial entities, estimating certain key properties of a complex financial system, including the implied level of systemic risk, requires detailed information about the structure of the underlying network of ...

Markov Chains With Maximum Return Time Entropy for Robotic Surveillance [PDF]

IEEE Transactions on Automatic Control, 2018
Motivated by robotic surveillance applications, this paper studies the novel problem of maximizing the return time entropy of a Markov chain, subject to a graph topology with travel times and stationary distribution.

Task-based differences in brain state dynamics and their relation to cognitive ability

NeuroImage, 2023
Transient patterns of interregional connectivity form and dissipate in response to varying cognitive demands. Yet, it is not clear how different cognitive demands influence brain state dynamics, and whether these dynamics relate to general cognitive ...

Calculation of Free Energy Consumption in Gene Transcription with Complex Promoter Structure

Complexity, 2020
From the viewpoint of thermodynamics, gene transcription necessarily consumes free energy due to nonequilibrium processes. On the other hand, regulatory molecules present on the core promoter of a gene interact often in a dynamic, highly combinatorial ...

Large deviations and fluctuation theorems for cycle currents defined in the loop-erased and spanning tree manners: A comparative study

Physical Review Research, 2023
The cycle current is a crucial quantity in stochastic thermodynamics. The absolute and net cycle currents of a Markovian system can be defined in the loop-erased (LE) or spanning tree (ST) manner.
