Femtosecond pulses in a dense two-level medium: Spectral transformations, transient processes, and collisional dynamics
Femtosecond pulses dense two-level medium Spectral transformations transient processes collisional dynamics
2011/8/5
Abstract: Propagation of ultrashort optical pulses in a dense resonant medium is considered in the semiclassical limit. In our analysis, we place emphasis on several main points. First, we study trans...
Transient shear banding in entangled polymers: a study using the Rolie-Poly model
Transient shear banding Rolie-Poly model
2010/11/24
Spatially inhomogeneous shear flow occurs in entangled polymer solutions, both as steady state shear banding and transiently after a large step strain or during start up to a steady uniform shear rate...
Age-dependent transient shear banding in soft glasses
Age-dependent transient shear soft glasses
2010/11/24
We study numerically the formation of long-lived transient shear bands during shear startup within two models of soft glasses (a simple fluidity model and an adapted ‘soft glassy rheology’ model). The...
Huge progeny production during the transient of a quasi-species model of viral infection, reproduction and mutation
quasi-species model viral infection reproduction
2010/11/17
Eigen's quasi-species model describes viruses as ensembles of different mutants of a high fitness "master" genotype. Mutants are assumed to have lower fitness than the master type, yet they coexist wi...
Non-degenerate four-wave mixing in rubidium vapor: transient regime
Non-degenerate four-wave mixing rubidium vapor transient regime
2010/11/9
We investigate the transient response of the generated light from Four-Wave Mixing (FWM) in the diamond configuration using a step-down field excitation. The transients show fast decay times and oscil...
Transient energy excitation in shortcuts to adiabaticity for the time dependent harmonic oscillator
Transient energy shortcuts adiabaticity time dependent harmonic oscillator
2010/10/21
There is recently a surge of interest to cut down the time it takes to change the state of a quantum system adiabatically. We study for the time-dependent harmonic oscillator the transient energy exci...
Design of a 1.2 GSPS single-channel real-time long-distance transmission sampling system for fast-transient signal
fast-transient signal nanosecond digital forward-sampling real-time long-distance transmission
2009/8/14
This article has introduced the origin and speciality of fast-transient signal, and told the meaning of researching on fast-transient signal. The main troubles of sampling on fast-transient signal is...
