Analysis of Localization Phenomena in Weakly Interacting Disordered Lattice Gases
T. Schulte, S. Drenkelforth, J. Kruse +6
Disorder plays a crucial role in many systems particularly in solid state physics. However, the disorder in a particular system can usually not be chosen or controlled. We show tha…
