Thermodynamics, stability and Hawking-Page transition of Kerr black holes from R\'enyi statistics [PDF]
, 2017 Thermodynamics of rotating black holes described by the R\'enyi formula as equilibrium and zeroth law compatible entropy function is investigated. We show that similarly to the standard Boltzmann approach, isolated Kerr black holes are stable with ...

A simple probabilistic construction yielding generalized entropies and divergences, escort distributions and q-Gaussians [PDF]
, 2012 We give a simple probabilistic description of a transition between two states which leads to a generalized escort distribution. When the parameter of the distribution varies, it defines a parametric curve that we call an escort-path.

Entanglement Entropy of Disjoint Regions in Excited States : An Operator Method [PDF]
, 2014 We develop the computational method of entanglement entropy based on the idea that $Tr\rho_{\Omega}^n$ is written as the expectation value of the local operator, where $\rho_{\Omega}$ is a density matrix of the subsystem $\Omega$. We apply it to consider

Negative Rényi entropy and brane intersection
Journal of High Energy Physics, 2023 In this work, we revisit the calculation of Rényi entropy in AdS3/(B)CFT2. We find that gravity solutions with brane intersection will lead to negative Rényi entropy.

Tsallis entropy measure of noise-aided information transmission in a binary channel [PDF]
, 2011 Noise-aided information transmission via stochastic resonance is shown and analyzed in a binary channel by means of information measures based on the Tsallis entropy.

Page curves and typical entanglement in linear optics [PDF]
Quantum, 2023 Bosonic Gaussian states are a special class of quantum states in an infinite dimensional Hilbert space that are relevant to universal continuous-variable quantum computation as well as to near-term quantum sampling tasks such as Gaussian Boson Sampling ...

Dynamics of entanglement entropy of interacting fermions in a 1D driven harmonic trap [PDF]
, 2017 Following up on a recent analysis of two cold atoms in a time-dependent harmonic trap in one dimension, we explore the entanglement entropy of two and three fermions in the same situation when driven through a parametric resonance.

Journal of High Energy Physics, 2021 We study the excited state Rényi entropy and subsystem Schatten distance in the two-dimensional free massless non-compact bosonic field theory, which is a conformal field theory.

Topologically Protected Negative Entanglement. [PDF]
Adv Sci (Weinh)It is revealed that topological flat‐band edge states can lead to robust unconventional negative entanglement entropy scaling. This arises from a new mechanism of non‐Hermitian critical skin compression (nHCSC), which strongly “compresses” quantum information beyond flat‐band degeneracy.
