The transient and stationary characteristics of a one-dimensional quantum hydrodynamic model are comparatively studied for semiconductor charge transport in a r
We present a simple and compact design for an all-solid-state laser amplifier system which can output 9.43-kHz 630-ps, 3.5-W pulse trains under 20W absorbed pum
We investigate a cosmological model of a phantom energy with a variable cosmological constant (A) depending on the energy density (p) as A α ρ-α, α = const
