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…

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…
