Relativistic Landau quantization in non-uniform magnetic field and its applications to white dwarfs and quantum information

open access: yesSciPost Physics, 2021
We investigate the two-dimensional motion of relativistic cold electrons in the presence of ‘strictly’ spatially varying magnetic fields satisfying, however, no magnetic monopole condition.

DYNAMICS OF MAGNETIC FLUID CAPILLARY RISE IN POROUS MEDIUM

open access: yesНаука. Инновации. Технологии, 2022
Bstract: In the present work the capillary flow of magnetic fluid in a single cylindrical capillary and in a porous medium under the action of a non-uniform magnetic field is studied experimentally. The dynamics of the capillary rise has been considered.

Magnetic Stability Analysis for the Geodynamo [PDF]

open access: yes, 2004
Kinematic dynamo modelling addresses the growth of magnetic fields under the action of fluid flow, effected in the geophysical case by the action of the convecting electrically conducting outer core and magnetic diffusion. In this study, we prescribe the

Numerical analysis of quantum-mechanical non-uniform E x B drift: Non-uniform electric field [PDF]

open access: yes, 2016
We have numerically solved the two-dimensional time-dependent Schrodinger equation for a charged particle in the presence of a non-uniform electric field E = E (1-y/L-E) e(y) as well as a non-uniform magnetic field B = B (1-y/L-B) e(z).

Deformation of a magnetic liquid drop in an applied non-stationary uniform magnetic field

open access: yesEPJ Web of Conferences, 2018
Small steady-state deformational oscillations of a drop of magnetic liquid in a nonstationary uniform magnetic field are theoretically investigated. The drop is suspended in another magnetic liquid immiscible with the former.
