An Extension of the Vector-Play Model to the Case of Magneto-Elastic Loadings
IEEE Access, 2022 Accurate modeling of the coupling between mechanical and magnetic behavior is a key challenge for designing many electromagnetic devices. The requirements for such modeling are notably the ability to consider multiaxial configurations, thermodynamic ...

On Measuring Divergence for Magnetic Field Modeling
The Astrophysical Journal, 2020 Abstract A physical magnetic field has a divergence of zero. Numerical error in constructing a model field and computing the divergence, however, introduces a finite divergence into these calculations. A popular metric for measuring divergence is the average fractional flux

Network model of localization in a random magnetic field [PDF]
Physical Review B, 1995 We consider a network model of snake states to study the localization problem of non-interacting fermions in a random magnetic field with zero average. After averaging over the randomness, the network of snake states is mapped onto $M$ coupled SU$(2N)$ spin chains in the $N \rightarrow 0$ limit.

A dynamo model of Jupiter’s magnetic field [PDF]
Icarus, 2014 Jupiter's dynamo is modelled using the anelastic convection-driven dynamo equations. The reference state model is taken from French et al. [2012]. Astrophys. J. Suppl. 202, 5, (11pp), which used density functional theory to compute the equation of state and the electrical conductivity in Jupiter's interior.

Progress in the modeling of Earth and planetary internal magnetic fields
地球与行星物理论评A majority of the planets in the Solar System are characterized by intrinsic magnetic fields that co-rotate with these celestial bodies. With ongoing advances in human deep-space exploration, magnetic field models have been established for all known ...

Vortex deconfinement in the XY model with a magnetic field [PDF]
Annals of Physics, 2003 We study vortex unbinding for the classical two-dimensional XY model in a magnetic field on square and triangular lattices. A renormalization group analysis combined with duality in the model shows that at high temperature and high field, the vortices unbind as the magnetic field is lowered in a two-step process: strings of overturned spins first ...

AI-driven modeling of modulated magnetoelectric magnetic field sensors [PDF]
APL Machine LearningModulated magnetoelectric (ME) sensors enable the detection of low-frequency, small-amplitude magnetic fields. Their performance is governed by a high-dimensional parameter space that combines the nonlinear coupling of magnetic, electric, and mechanical ...

LOCAL MAGNETIZATION IN CRITICAL ISING MODEL WITH BOUNDARY MAGNETIC FIELD [PDF]
Modern Physics Letters A, 1994 We describe a simple way to derive spin correlation functions in 2-D Ising model at critical temperature but with nonzero magnetic field at the boundary. Local magnetization (i.e. one-point function) is computed explicitly for half-plane and disk geometries.
