The conversion of an ordinary wave to an extraordinary wave in a 2D inhomogeneous slab model of the plasma confined by a sheared magnetic field is studied analytically.

Weexplore the effect of the externalmagnetic andAharonov–Bohm (AB) flux fields on the energy levels of Dirac particle subjects to mixed scalar and vector anharmonic oscillator field in the twodimensional (2D) space. We calculate the exact energy eigenvalues and the correspondingun-normalized two-spinor-components wave functions in terms of the chemical potential parameter, magnetic field streng...

High field wigglers for synchrotron radiation production have usually rather complex distribution of magnetic field, and particle motion through it can hardly be treated analytically. This paper concerns a simple and reliable receipt for a symplectic algorithm to track a particle through such fields. Input data for numeric integration are taken directly from results of magnetic mapping or simul...

The electronic structure of a 2D gas subjected to a tilted magnetic field, with a strong component parallel to the GaAs/AlGaAs interface and a weak component oriented perpendicularly, is studied theoretically. It is shown that the parallel field component modifies the originally circular shape of a Fermi contour while the perpendicular component drive an electron by the Lorentz force along a Fe...

the entanglement at zero-temperature is studied in a two-qubit xz spin-1/2 chain model in anexternal magnetic field which is applied in the z direction. we have obtained an analytical relation forthe effect of the external magnetic field on the concurrence. it is shown that the ground state of thesystem depends on the strength of exchange coupling. we have shown that the analytical relation oft...

Abstract In lattice compact gauge theories, we must impose the admissibility condition to have well-defined topological sectors. The condition, however, usually forbids presence of magnetic operators, and it is not so trivial if one can study physics objects that depends on term, such as Witten effect, lattice. this paper, address question in case 2D scalars would be simplest examples having an...

We have investigated the transition temperature Tc(H) of superconductivity in quasi-twodimensional (Q2D) tight-binding electrons in a strong magnetic field. When the magnetic field is parallel to 2D conducting plane, Tc(H) of the Q2D superconductor is shown to increase in an oscillatory manner as the magnetic field becomes large and to reach Tc(0) in a strong magnetic field limit for the spin-t...
