Stückelberg-Interferometry with ultra-cold atoms
Patrick Plötz, Sandro Wimberger
We show that and how ultra-cold atoms in an accelerated two-band lattice are a controlled realization of Landau--Zener--Stückelberg interferometry.

Effective spin model for interband transport in a Wannier-Stark lattice system
Patrick Plötz, Peter Schlagheck, Sandro Wimberger
We show that the interband dynamics in a tilted two-band Bose-Hubbard model can be reduced to an analytically accessible spin model in the case of resonant interband oscillations.…
