Anomalous Quantum Reflection of Bose-Einstein Condensates from a Silicon Surface: The Role of Dynamical Excitations
Anomalous Quantum Reflection of Bose-Einstein Condensates from a Silicon Surface: The Role of Dynamical Excitations
We investigate the effect of interatomic interactions on the quantum-mechanical reflection of Bose-Einstein condensates from regions of rapid potential variation. The reflection process depends critically on the density and incident velocity of the condensate. For low densities and high velocities, the atom cloud has almost the same form before and …
