We find that there are two time scales t and ε ln t in the asymptotic behaviour of diffusion process in the porous medium, which give us a new insight to the a
We present the theoretical and experimental results of water surface wave in a trough with periodical topographic bottom under parametric excitation. There are
We perform a theoretical study on a low dark current InGaAs/GaAs very-long-wavelength (>12 μm) quantum well infrared photodetector (VLW-QWIP), based on a double
Molecular dynamics simulations are performed for water conGned in carbon nanotubes with various diameters (11.0-13.8 A). The simulations under an isobaric press
Numerical simulations show that proper fundamental mode-locking repetition range of hybrid soliton pulse source where transform-limited pulses are obtained is e
Recently, two papers presented by Ortigoso et al. [Phys. Rev. Lett. 93 (2004) 073001 and Phys. Rev. A 72(2005) 053401] develop a novel strategy in which the bes
We propose an inverse idea of controlling the evolution of the population inversion by a time-dependent coupling between the cavity field and a two-level system
We study the inclusive production of doubly heavy baryon ([I])cc at polarized photon collider.Our results show that proper choice of the initial beam polarizati
