Tsallis Ensemble as an Exact Orthode
, 2006 We show that Tsallis ensemble of power-law distributions provides a mechanical model of nonextensive equilibrium thermodynamics for small interacting Hamiltonian systems, i.e., using Boltzmann's original nomenclature, we prove that it is an exact orthode.

Application of Renyi entropy for ultrasonic molecular imaging [PDF]
The Journal of the Acoustical Society of America, 2009 Previous work has demonstrated that a signal receiver based on a limiting form of the Shannon entropy is, in certain settings, more sensitive to subtle changes in scattering architecture than conventional energy-based signal receivers [M. S. Hughes et al., J. Acoust. Soc. Am. 121, 3542–3557 (2007)]. In this paper new results are presented demonstrating

Robust estimation of a Markov chain transition matrix from multiple sample paths
Statistica Neerlandica, Volume 80, Issue 1, February 2026.Markov chains are fundamental models for stochastic dynamics, with applications in a wide range of areas such as population dynamics, queueing systems, reinforcement learning, and Monte Carlo methods. Estimating the transition matrix and stationary distribution from observed sample paths is a core statistical challenge, particularly when multiple ...

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.

Quantum Monte Carlo calculation of entanglement Renyi entropies for generic quantum systems
, 2012 We present a general scheme for the calculation of the Renyi entropy of a subsystem in quantum many-body models that can be efficiently simulated via quantum Monte Carlo.

Nearly Hamilton cycles in sublinear expanders and applications
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract We develop novel methods for constructing nearly Hamilton cycles in sublinear expanders with good regularity properties, as well as new techniques for finding such expanders in general graphs. These methods are of independent interest due to their potential for various applications to embedding problems in sparse graphs.

Topologically Protected Negative Entanglement
Advanced Science, Volume 13, Issue 3, 14 January 2026.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.
