News from the quantum kicked rotor
Speaker:Sandro Wimberger (Heidelberg University)
Abstract:Despite its simplicity and its long-standing history of research, the quantum kicked rotor model continues to offer many interesting facets. Most of the relevant recent research has been triggered by experimental realisations of the model, which include important amendments. Here an overview over a few recent experimental results is given, backed by theoretical developments of the original model. The new aspects include all-optical realisations with perfect control over initial states, the engineering of phase space by phase control of the kicking potential, and last but not least a series of results close to the quantum resonances of the kicked rotor where ballistic transport is possible. In the latter regime, the system is very successfully described by a semi-classical theory which eases new important predictions.

Finite Density QCD from an effective lattice theory
Speaker:Prof. Owe Philipsen (Goethe University Frankfurt )
Abstract:Using strong coupling and hopping expansions, an effective 3d theory for lattice QCD with Wilson fermions is derived, which is valid for heavy quarks. The sign problem in the effective theory is significantly milder than in the original one and can furthermore be solved by flux formulations or complex Langevin methods. I present results for the deconfinement transition and its critical end point for all baryon densities as well as the onset transition to nuclear matter at zero temperature.
