Superellipse Equation Models Ferromagnet Magnetization

Published:Dec 31, 2025 10:35
1 min read
ArXiv

Analysis

This paper proposes a novel approach to model the temperature dependence of spontaneous magnetization in ferromagnets like Ni2MnGa, nickel, cobalt, and iron. It utilizes the superellipse equation with a single dimensionless parameter, simplifying the modeling process. The key advantage is the ability to predict magnetization behavior near the Curie temperature (Tc) by measuring magnetization at lower temperatures, thus avoiding difficult experimental measurements near Tc.
Reference

“The temperature dependence of the spontaneous magnetization of Ni2MnGa and other ferromagnets can be described in reduced coordinates by the superellipse equation using a single dimensionless parameter.”

ArXiv

Analysis

This paper analyzes the spectral evolution of GRB 161117A, a long-duration gamma-ray burst, revealing a transition from thermal to non-thermal emission. This transition provides insights into the jet composition, suggesting a shift from a fireball to a Poynting-flux-dominated jet. The study infers key parameters like the bulk Lorentz factor, radii, magnetization factor, and dimensionless entropy, offering valuable constraints on the physical processes within the burst. The findings contribute to our understanding of the central engine and particle acceleration mechanisms in GRBs.
Reference

“The spectral evolution shows a transition from thermal (single BB) to hybrid (PL+BB), and finally to non-thermal (Band and CPL) emissions.”

Time-Dependent Accretion Disk Evolution with MHD Winds

Published:Dec 30, 2025 05:40
1 min read
ArXiv

Analysis

This paper provides Green's function solutions for the time evolution of accretion disks, incorporating the effects of magnetohydrodynamic (MHD) winds. It's significant because it offers a theoretical framework to understand how these winds, driven by magnetic fields, influence the mass accretion rate and overall disk lifetime in astrophysical systems like protoplanetary disks. The study explores different boundary conditions and the impact of a dimensionless parameter (ψ) representing wind strength, providing insights into the dominant processes shaping disk evolution.
Reference

“The paper finds that the disk lifetime decreases as the dimensionless parameter ψ (wind strength) increases due to enhanced wind-driven mass loss.”

Critique of a Model for the Origin of Life

Published:Dec 29, 2025 13:39
1 min read
ArXiv

Analysis

This paper critiques a model by Frampton that attempts to explain the origin of life using false-vacuum decay. The authors point out several flaws in the model, including a dimensional inconsistency in the probability calculation and unrealistic assumptions about the initial conditions and environment. The paper argues that the model's conclusions about the improbability of biogenesis and the absence of extraterrestrial life are not supported.
Reference

“The exponent $n$ entering the probability $P_{ m SCO}\sim 10^{-n}$ has dimensions of inverse time: it is an energy barrier divided by the Planck constant, rather than a dimensionless tunnelling action.”
