Maximum Induced Trees and Forests of Bounded Degree in Random Graphs
Random Structures &Algorithms, Volume 68, Issue 4, July 2026.ABSTRACT The asymptotic behavior of the maximum sizes of induced trees and forests has been studied extensively in the last few decades, though the overall picture is far from being complete. In this paper, we close several significant gaps: (1) We prove 2‐point concentration of the maximum sizes of an induced forest and an induced tree with maximum ...

The effect of Rényi entropy on Hawking radiation
, 2022 It is widely believed that Hawking radiation originates from excitations near the horizons of black holes (Hawking in Commun Math Phys 43:199, 1975, Giddings in Phys Lett B 754:39, 2016, Mathur in Class Quantum Gravity 26:224001, 2009). However, Giddings

SoftwareX, 2019 This paper shows how to quantify and test for the information flow between two time series with Shannon transfer entropy and Rényi transfer entropy using the R package RTransferEntropy. We discuss the methodology, the bias correction applied to calculate

Measuring the Rényi entropy of a two-site Fermi-Hubbard model on a trapped ion quantum computer [PDF]
Physical Review A, 2017 The efficient simulation of correlated quantum systems is a promising near-term application of quantum computers. Here, we present a measurement of the second R\'enyi entropy of the ground state of the two-site Fermi-Hubbard model on a five-qubit ...

Small Structures, Volume 7, Issue 7, July 2026.We used advanced image analysis on 3D‐reconstructed filler particle networks in silver‐PDMS conductive polymer composites to decouple network structure and particle–particle contact resistance above the percolation threshold. The silver loading–dependent changes in network structure were not strong enough to change the macroscopic conductivity, proving

Journal of High Energy PhysicsWe study multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals. The Rényi entropy evaluation involves computing the partition function of the theory on Riemann surfaces with genus g > 1.

On the Entropy Power Inequality for the Rényi Entropy of Order [0, 1] [PDF]
IEEE Transactions on Information Theory, 2017 Using a sharp version of the reverse Young inequality, and a Rényi entropy comparison result due to Fradelizi, Madiman, and Wang (2016), the authors derive Rényi entropy power inequalities for log-concave random vectors when Rényi parameters belong to [0,

Mid‐Domain Effect and Wooded Habitat Shape Mediterranean Reptile Communities
Biological Diversity, Volume 3, Issue 2, Page 65-82, June 2026.Analyzing a large number of reptiles observed across protected areas in Central Italy, we tested whether the mid‐domain effect explains hump‐shaped richness–elevation patterns. Species richness was best predicted by the combined influence of geometric constraints and woodland cover, revealing two contrasting species clusters and offering a robust ...

Quantum Information Measures of a Dirichlet Waveguide with Neumann Window(s)
Advanced Quantum Technologies, Volume 9, Issue 6, June 2026.ABSTRACT Engineering boundary conditions in low‐dimensional structures provides a simple yet powerful way of shaping how quantum information is stored and transported. We investigate a flat 2D Dirichlet waveguide containing one or two finite Neumann windows and compute the bound states in both position and momentum space as functions of the window ...
