Asymmetric Time Evolution And Indistinguishable Events
With a time asymmetric theory, in which quantum mechanical time evolution is given by a semigroup of operators rather than by a group, the states of open systems are represented by density operators exhibiting a branching ...
Cold Atom Ballistics By Coherent Control
We use the technique of Stimulated Raman adiabatic passage (STIRAP) to affect transport of ultracold atoms between two optical lattices in relative motion. We show, using Floquet analysis and degenerate perturbation theory, ...
Temperature Dependence Of Brillouin Light Scattering Spectra Of Acoustic Phonons In Silicon
Electrons, optical phonons, and acoustic phonons are often driven out of local equilibrium in electronic devices or during laser-material interaction processes. The need for a better understanding of such non-equilibrium ...
