QCD Wehrl and Entanglement Entropies in Gluon Spectator Model

Published:Dec 31, 2025 13:25
1 min read
ArXiv

Analysis

This paper explores the use of Wehrl entropy, derived from the Husimi distribution, to analyze the entanglement structure of the proton in deep inelastic scattering, going beyond traditional longitudinal entanglement measures. It aims to incorporate transverse degrees of freedom, providing a more complete picture of the proton's phase space structure. The study's significance lies in its potential to improve our understanding of hadronic multiplicity and the internal structure of the proton.
Reference

“The entanglement entropy naturally emerges from the normalization condition of the Husimi distribution within this framework.”

Dynamics of Collapsing Particles: A Dynamical System Approach

Published:Dec 31, 2025 11:58
1 min read
ArXiv

Analysis

This paper investigates the collision dynamics of four inelastic hard spheres in one dimension, a problem relevant to understanding complex physical systems. The authors use a dynamical system approach (the b-to-b mapping) to analyze collision orders and identify periodic and quasi-periodic orbits. This approach provides a novel perspective on a well-studied problem and potentially reveals new insights into the system's behavior, including the discovery of new periodic orbit families and improved bounds on stable orbits.
Reference

“The paper discovers three new families of periodic orbits and proves the existence of stable periodic orbits for restitution coefficients larger than previously known.”

Inelastic Dilation Causes Coseismic Fault Depressurization

Published:Dec 30, 2025 00:20
1 min read
ArXiv

Analysis

This paper is significant because it highlights the importance of considering inelastic dilation, a phenomenon often overlooked in hydromechanical models, in understanding coseismic pore pressure changes near faults. The study's findings align with field observations and suggest that incorporating inelastic effects is crucial for accurate modeling of groundwater behavior during earthquakes. The research has implications for understanding fault mechanics and groundwater management.
Reference

“Inelastic dilation causes mostly notable depressurization within 1 to 2 km off the fault at shallow depths (< 3 km).”

Charge Dynamics in Cuprate Superconductors: A Theoretical Review

Published:Dec 26, 2025 05:04
1 min read
ArXiv

Analysis

This paper reviews recent theoretical advancements in understanding the charge dynamics of doped carriers in high-temperature cuprate superconductors. It highlights the importance of strong electronic correlations, layered crystal structure, and long-range Coulomb interaction in governing the collective behavior of these carriers. The paper focuses on acoustic-like plasmons, charge order tendencies, and the challenges in reconciling experimental observations across different cuprate systems. It's significant because it synthesizes recent progress and identifies open questions in a complex field.
Reference

“The emergence of acousticlike plasmons has been firmly established through quantitative analyses of resonant inelastic x-ray scattering (RIXS) spectra based on the t-J-V model.”

Long-Range Coulomb Interaction in Cuprate Superconductors

Published:Dec 26, 2025 05:03
1 min read
ArXiv

Analysis

This review paper highlights the importance of long-range Coulomb interactions in understanding the charge dynamics of cuprate superconductors, moving beyond the standard Hubbard model. It uses the layered t-J-V model to explain experimental observations from resonant inelastic x-ray scattering. The paper's significance lies in its potential to explain the pseudogap, the behavior of quasiparticles, and the higher critical temperatures in multi-layer cuprate superconductors. It also discusses the role of screened Coulomb interaction in the spin-fluctuation mechanism of superconductivity.
Reference

“The paper argues that accurately describing plasmonic effects requires a three-dimensional theoretical approach and that the screened Coulomb interaction is important in the spin-fluctuation mechanism to realize high-Tc superconductivity.”
