| 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. |
