Traveling Fronts for (q,r)$(q, r)$‐Relativistic Operators: Existence and Asymptotic Properties
Mathematische Nachrichten, EarlyView.ABSTRACT A new reaction–diffusion model governed by a (q,r)$(q, r)$‐relativistic type diffusion, generalizing the p$p$‐relativistic one and encompassing singular and/or degenerate diffusivity, is introduced. In the monostable case, some existence results for (decreasing) fronts are then provided, exploiting the study of a suitable two‐point problem ...

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3
Small, EarlyView.Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...

Path integral quantization of generalized Stueckelberg electrodynamics: A Faddeev-Jackiw approach
Nuclear Physics B, 2023 We build a setup for path integral quantization through the Faddeev-Jackiw approach, extending it to include Grassmannian degrees of freedom, to be later implemented in a model of generalized electrodynamics that involves fourth-order derivatives in the ...

Rare Lightning and Convection Characteristics During Two Successive Tornadoes in Southern China
High Voltage, EarlyView.ABSTRACT Systematic investigations into lightning characteristics of tornado storms in China remain scarce. This study comprehensively analyses rare lightning behaviour and overshooting top characteristics for two successive tornadoes during a long‐lived supercell in southern China on 27 April 2024.

Wave Tracing: Generalizing The Path Integral To Wave Optics
Computer Graphics Forum, EarlyView.Abstract Modeling the wave nature of light and the propagation and diffraction of electromagnetic fields is crucial for the accurate simulation of many phenomena, yet wave simulations are significantly more computationally complex than classical ray‐based models.

Special solutions of coupled classical harmonic oscillators with the addition of magnetic monopoles
Physics OpenIn this paper, we undertake a thorough investigation into the existence of magnetic monopoles, elusive particles theorized to possess isolated north or south magnetic poles. These hypothetical entities have long captured the imagination of physicists and

Electromagnetism as an emergent phenomenon: a step-by-step guide
New Journal of Physics, 2014 We give a detailed description of electrodynamics as an emergent theory from condensed-matter-like structures, not only per se but also as a warm-up for the study of the much more complex case of gravity.
