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 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...
