A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels

open access: yesGeophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.

Eigen solutions of the Schrӧdinger equation and the thermodynamic stability of the black hole temperature

open access: yesResults in Physics, 2018
The approximate analytical solutions of the Schrӧdinger equation for Eckart potential is obtained via supersymmetry shape invariance approach. The energy equation and the corresponding wave function are obtained in a closed and compact form.

Dynamical entropic measure of nonclassicality of phase-dependent family of Schrödinger cat states

open access: yesScientific Reports, 2023
The phase-space approach based on the Wigner distribution function is used to study the quantum dynamics of the three families of the Schrödinger cat states identified as the even, odd, and Yurke–Stoler states.

Fuzzy Clustering Methods with Rényi Relative Entropy and Cluster Size

open access: yesMathematics, 2021
In the last two decades, information entropy measures have been relevantly applied in fuzzy clustering problems in order to regularize solutions by avoiding the formation of partitions with excessively overlapping clusters.

Scaling of Entanglement Entropy for the Heisenberg Model on Clusters Joined by Point Contacts

open access: yes, 2016
The scaling of entanglement entropy for the nearest neighbor antiferromagnetic Heisenberg spin model is studied computationally for clusters joined by a single bond.

Application of Renyi entropy for ultrasonic molecular imaging [PDF]

open access: yesThe 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

Beyond Co‐Occurrence: Multi‐Scale Evidence for Segregation‐Dominated Plant Networks in the French Alps

open access: yesEcology Letters, Volume 29, Issue 5, May 2026.
Using high‐resolution spatial data and a multi‐scale statistical framework, we disentangle plant co‐occurrence from true spatial associations across alpine communities in the French Alps. We discovered that local species associations are dependent on soil acidity and nitrogen rather than temperature. By building a global network from these associations,

Multi-charged moments and symmetry-resolved Rényi entropy of free compact boson for multiple disjoint intervals

open access: yesJournal of High Energy Physics
We 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

open access: yes, 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.
