LOCAL MAGNETIZATION IN CRITICAL ISING MODEL WITH BOUNDARY MAGNETIC FIELD [PDF]

open access: yesModern 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.

The extraordinary complex magnetic field of the helium-strong star HD 37776

open access: yes, 2010
The early-type chemically peculiar stars often show strong magnetic fields on their surfaces. These magnetic topologies are organized on large scales and are believed to be close to an oblique dipole for most of the stars. In a striking exception to this

Toroidal modeling of penetration of the resonant magnetic perturbation field [PDF]

open access: yes, 2013
A toroidal, quasi-linear model is proposed to study the penetration dynamics of the resonant magnetic perturbation (RMP) field into the plasma. The model couples the linear, fluid plasma response to a toroidal momentum balance equation, which includes ...

MAGNETIC FIELD GENERATION IN HIGGS INFLATION MODEL [PDF]

open access: yesInternational Journal of Modern Physics A, 2012
We study the generation of magnetic field in Higgs inflation models where the Standard Model Higgs boson has a large coupling to the Ricci scalar. We couple the Higgs field to the electromagnetic fields via a nonrenormalizable dimension six operator suppressed by the Planck scale in the Jordan frame. We show that by choosing the Higgs coupling λ(MZ) =

Characterization of anomalous Zeeman patterns in complex atomic spectra

open access: yes, 2012
The modeling of complex atomic spectra is a difficult task, due to the huge number of levels and lines involved. In the presence of a magnetic field, the computation becomes even more difficult.

Modeling of High-Precision Sea Surface Geomagnetic Field in the Northern South China Sea Based on PSO-BP Neural Network

open access: yesJournal of Marine Science and Engineering
In existing regional geomagnetic field modeling, the smoothness of basic functions and the insufficient data constraints in marginal regions lead to the omission of detail features and extrapolation oscillations.

A magneto-viscoelasticity problem with a singular memory kernel

open access: yes, 2016
The existence of solutions to a one-dimensional problem arising in magneto-viscoelasticity is here considered. Specifically, a non-linear system of integro-differential equations is analyzed, it is obtained coupling an integro-differential equation ...

Guided flows in coronal magnetic flux tubes [PDF]

open access: yes, 2017
There is evidence for coronal plasma flows to break down into fragments and to be laminar. We investigate this effect by modeling flows confined along magnetic channels. We consider a full MHD model of a solar atmosphere box with a dipole magnetic field.
