Our group at the University of Luxembourg pursues a wide range of research interests within the realm of mesoscopic systems. With typical length scales of nanometers to micrometers, mesoscopic systems are already rather large compared to quantum systems like atoms and molecules. Nevertheless they can display a plethora of interesting quantum phenomena, such as interference effects and many-particle quantum dynamics. We use various analytical and numerical techniques to study such systems.
Our paper about the Coulomb drag in a graphene double layer in the hydrodynamic regime has been published as a Letter in Physical Review B. In this paper, we show that a previously unknown electron viscosity term can change the sign of the drag conductivity when the relative electron density in the two layers is changed.
Our paper about the role of the Meisser current for the induced superconductivity at the interface between a superconductor and a quantum Hall edge states has just been published in Physical Review Research.
