Duality between the Deconfined Quantum-Critical Point and the Bosonic Topological Transition

Physical Review X, 2017
Recently, significant progress has been made in (2+1)-dimensional conformal field theories without supersymmetry. In particular, it was realized that different Lagrangians may be related by hidden dualities; i.e., seemingly different field theories may ...

Global Ionospheric Scintillation Estimation Based on Phase Screen Modeling From One‐Dimensional Satellite Data

Space Weather, Volume 23, Issue 1, January 2025.
Abstract Ionospheric scintillations, which usually manifest as sudden, rapid fluctuations in radio wave signal phase and amplitude, challenge the reliability of satellite communication and navigation. Based on the single phase screen assumption, this study uses the one‐dimensional (1D) in‐situ plasma density data of ESA's Swarm constellation data to ...

TIE‐GCM ROPE ‐ Dimensionality Reduction: Part I

Space Weather, Volume 23, Issue 1, January 2025.
Abstract Physics‐based models of the ionosphere‐thermosphere system have been touted as the next big thing in the context of drag modeling and space operations for decades. However, the computational complexity of such models have primarily kept them being used operationally.

Unveiling Approximate Analytical Solutions for Fractional‐Order Partial Differential Equations in Physical Processes

Journal of Mathematics, Volume 2025, Issue 1, 2025.
This paper aims to tackle the challenge of deriving accurate analytical solutions for three classes of fractional‐order partial differential equations (PDEs)—the Sharma–Tasso–Olver (STO), cubic nonlinear Schrödinger (Sch), and Fokker–Planck (FP) equations, which represent intricate phenomena in fluid dynamics, quantum mechanics, and statistical physics.

Signature of matter–field coupling in quantum–mechanical statistics

Frontiers in Quantum Science and Technology
The connection between the intrinsic angular momentum (spin) of particles and quantum statistics is established by considering the response of identical particles to a common background radiation field.

Chern-Simons induced thermal friction on axion domain walls

Journal of High Energy Physics
We study the dynamics and interactions of the solitonic domain walls that occur in realistic axion electrodynamics models including the Chern-Simons interaction, aϵ μνλσ F μν F λσ , between an axion a(x) of mass m a , and a massless U(1) gauge field, e.g.
