Abstract:
Bremsstrahlung X-rays are generated when the ultra-short ultra-intense laser interacts with solid targets. The transport of hot electrons in solid targets and the generation of bremsstrahlung X-rays were simulated using Monte Carlo method. Simulation...

Abstract:
Anomalous transport of inertial Levy flight subject to nonlinear friction in force-free potential is studied. By introducing velocity-dependent nonlinear friction, long-jump Levy particles are constrained, and the dynamical behavior of the particles ...

Abstract:
Non-equilibrium systems have been observed at almost all levels of natural and manmade systems, which are characterized by non-zero continuous traffic currents. The totally asymmetric simple exclusion process (TASEP) has been regarded as a paradigm f...
