Abstract :

Predicting the dynamics of an interacting many-body system is often a challenging task either by an analytical method or by numerical simulation. The way to a faster and more accurate solution was embedded in the vision of Feynman’s quantum computers for universal quantum simulations. Ultracold quantum gases offer unique possibilities to simulate quantum dynamics in a highly controllable and precisely tuneable setup. In this talk, I will present an introduction of the field providing a state-of-the-art picture. Specifically, I will present the results obtained with a rubidium Bose-Einstein condensate loaded in an optical lattice. Using a scanning electron microscope [1], we prepared the initial state and observed “Negative differential conductivity” in an interacting quantum gas [2]. Finally, I will present my future research plan.
