Logarithmic black hole entropy corrections and holographic Rényi entropy

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
The entanglement and Rényi entropies for spherical entangling surfaces in CFTs with gravity duals can be explicitly calculated by mapping these entropies first to the thermal entropy on hyperbolic space and then, using the AdS/CFT correspondence, to the ...

Entanglement susceptibility: Area laws and beyond

open access: yes, 2013
Generic quantum states in the Hilbert space of a many body system are nearly maximally entangled whereas low energy physical states are not; the so-called area laws for quantum entanglement are widespread.

The random graph process is globally synchronizing

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.
Abstract The homogeneous Kuramoto model on a graph G=(V,E)$G = (V,E)$ is a network of |V|$|V|$ identical oscillators, one at each vertex, where every oscillator is coupled bidirectionally (with unit strength) to its neighbors in the graph. A graph G$G$ is said to be globally synchronizing if, for almost every initial condition, the homogeneous Kuramoto

Practical Estimation of Renyi Entropy

open access: yes, 2020
Entropy Estimation is an important problem with many applications in cryptography, statistic,machine learning. Although the estimators optimal with respect to the sample complexity have beenrecently developed, there are still some challenges we address in this paper.The contribution is a novel estimator which is built directly on the birthday paradox ...

Effects of Punitive Measures on Free Riding and Collective Immunity Under Q‐Learning–Driven Epidemic Dynamics

open access: yesComplexity, Volume 2026, Issue 1, 2026.
Free‐riding behavior poses a critical challenge to achieving collective immunity in vaccination campaigns, particularly when individuals make decisions based on short‐term self‐interest. This study investigates how punitive interventions can mitigate free‐riding and enhance vaccination uptake under adaptive decision‐making.

Rényi complexity in mean-field disordered systems

open access: yesSciPost Physics
Configurational entropy, or complexity, plays a critical role in characterizing disordered systems such as glasses, yet its measurement often requires significant computational resources. Recently, Rényi entropy, a one-parameter generalization of Shannon

Wigner Function and Entanglement Entropy for Bosons from Non-Equilibrium Field Theory

open access: yes, 2018
We propose a new method of calculating entanglement entropy of a many-body interacting Bosonic system (open or closed) in a field theoretic approach without replica methods.

Harriss Generalized Kappa Distribution: Statistical Modeling and Practical Applications in Finance and Engineering

open access: yesEngineering Reports, Volume 7, Issue 12, December 2025.
This study introduces the four‐parameter Harris Generalized Kappa Distribution (HGKD), extending the two‐parameter Kappa model to better handle highly skewed data. Key statistical properties such as moments, entropies, and reliability measures are derived, and the model's applicability is demonstrated through real‐world lifetime datasets in finance and

Rates of convergence for Renyi entropy in extreme value theory

open access: yes, 2014
Max stable laws are limit laws of linearly normalized partial maxima of independent identically distributed random variables. Saeb (2014) proves that the Renyi entropy of order b (b > 1) of linear normalized maximum of iid random variables with ...
