Research Interests


Quantum transport

aves or quantum particles propagating in disordered environments display interference effects that alter the properties of classical diffusive transport and might explain, e.g., the high efficiency of photosynthetic complexes in the biological context. We especially study the role of nonlinearities in the scattering of photons by cold atoms and the propagation of bosons through random potentials.

Principal investigators: S. Shatokhin, T. Wellens, A. Buchleitner


Ultra-cold atoms

With the advent of (ultra-)cold atoms loaded in periodic or random potentials, a new arena for the experimental investigations of quantum many-body phenomena was opened; Our research interest is focused on characteristic features of open systems such as transport, scattering, leakage of particles and decoherence.

Principal investigators: A. Rodriguez, T. Wellens, A. Buchleitner


Quantum information

Entanglement in composite quantum systems can be regarded as the most genuine trait of quantum physics. For our group, important questions concern the characterization of many-particle entanglement, the control of entanglement by suitable laser pulses and its protection against decoherence.

Principal investigators: C. Gneiting, A. Buchleitner


Quantum chaos

Helium is a prototype of a strongly correlated and chaotic few-body system. Combining advanced parallel computation and semiclassical tools, we investigate the role and signatures of electronic correlations in single or double ionization processes, long-lived resonances in high-dimensional configuration space and electronic transport along the energy axis.
