Sound Waves in Backreaction-Affected Spacetime

Published:Dec 30, 2025 13:48

ArXiv

Analysis

This paper investigates the behavior of sound waves in a fluid system, modeling the effects of backreaction (the influence of the sound waves on the fluid itself) within the framework of analogue gravity. It uses a number-conserving approach to derive equations for sound waves in a dynamically changing spacetime. The key finding is that backreaction modifies the effective mass of the sound waves and alters their correlation properties, particularly in a finite-size Bose gas. This is relevant to understanding quantum field theory in curved spacetime and the behavior of quantum fluids.
Reference

“The backreaction introduces spacetime dependent mass and increases the UV divergence of the equal position correlation function.”

Frobenius-Optimal Projection for Conserving Linear Dynamical Models

Published:Dec 26, 2025 17:11
1 min read
ArXiv

Analysis

This paper addresses a crucial problem in data-driven modeling: ensuring physical conservation laws are respected by learned models. The authors propose a simple, elegant, and computationally efficient method (Frobenius-optimal projection) to correct learned linear dynamical models to enforce linear conservation laws. This is significant because it allows for the integration of known physical constraints into machine learning models, leading to more accurate and physically plausible predictions. The method's generality and low computational cost make it widely applicable.
Reference

“The matrix closest to $\widehat{A}$ in the Frobenius norm and satisfying $C^ op A = 0$ is the orthogonal projection $A^\star = \widehat{A} - C(C^ op C)^{-1}C^ op \widehat{A}$.”

Radiative Charged Higgs Vertices in 3HDMs

Published:Dec 25, 2025 18:41

ArXiv

Analysis

This paper investigates the radiative corrections to charged Higgs boson interactions in three Higgs doublet models (3HDMs). It focuses on the $H^+ W^- Z$ vertex, calculating it in different 3HDM types and comparing them to 2HDMs. The paper also explores the potential for detecting these interactions at the LHC via vector boson fusion (VBF), suggesting a possible smoking gun signal for 3HDMs.
Reference

“The results also indicate a sizeable increment ($\sim 100\%$) over the corresponding form factors in 2HDMs. In addition, we probe the $H_{1,2}^+ W^- Z$ vertices at the 14 TeV LHC using vector boson fusion (VBF).”

Energy-conserving finite difference scheme for compressible magnetohydrodynamic flow at low Mach numbers using nonconservative Lorentz force

Published:Dec 23, 2025 01:19
1 min read
ArXiv

Analysis

This article presents a numerical scheme for simulating magnetohydrodynamic (MHD) flow, focusing on energy conservation and low Mach number regimes. The use of a nonconservative Lorentz force is a key aspect of the method. The research likely aims to improve the accuracy and stability of MHD simulations, particularly in scenarios where compressibility effects are significant but the flow speeds are relatively low.
Reference

“The article's abstract or introduction would contain the most relevant quote, but without access to the full text, a specific quote cannot be provided. The core concept revolves around energy conservation and the nonconservative Lorentz force.”
