Precise coupling terms in adiabatic quantum evolution: The generic case
Volker Betz, Stefan Teufel
For multi-level time-dependent quantum systems one can construct superadiabatic representations in which the coupling between separated levels is exponentially small in the adiabat…
On the exit statistics theorem of many particle quantum scattering
Detlef Duerr, Stefan Teufel
We review the foundations of the scattering formalism for one particle potential scattering and discuss the generalization to the simplest case of many non interacting particles. W…
Precise coupling terms in adiabatic quantum evolution
Volker Betz, Stefan Teufel
It is known that for multi-level time-dependent quantum systems one can construct superadiabatic representations in which the coupling between separated levels is exponentially sma…
Propagation of Wigner functions for the Schroedinger equation with a perturbed periodic potential
Stefan Teufel, Gianluca Panati
Let be a lattice periodic potential and and external electromagnetic potentials which vary slowly on the scale set by the lattice spacing. It is shown that the Wigner…
