We investigate the accretion process for static spherically symmetric geometry, i.e., magnetically charged regular black hole with isotropic fluid. W'e obtain generalized expressions for the velocity (u(r)), spee...
A jet model for the jet power arising from a steady, optically thin, advection dominated accretion flow (ADAF) around a Kerr black hole (BH) is proposed. We investigate the typical numerical solutions of ADAF, and...

We theoretically and experimentally study the cavity modes in a gyromagnetic photonic crystal (GPC).Because the permeability of gyromagnetic material relies on the dc magnetic field exerted upon it,the band gap of the...

Because of the Zeeman splitting effect in diluted semiconductor (Zn,Cd,Mn)Se, the absorption spectrum of ZnSe/(Zn,Cd,Mn)Se quantum wells can be adjusted by magnetic field effectively. Within the effective-mass app...
