Anomalous quantum reflection of Bose-Einstein condensates from a silicon surface: the role of dynamical excitations
R. G. Scott, A. M. Martin, T. M. Fromhold +1
We investigate the effect of inter-atomic interactions on the quantum-mechanical reflection of Bose-Einstein condensates from regions of rapid potential variation. The reflection p…

Model for Breakdown of Laminar Flow of a Quantum Hall Fluid Around a Charged Impurity: Comparison with Experiment
A. M. Martin, K. A. Benedict, F. W. Sheard +1
In samples used to maintain the US resistance standard the breakdown of the dissipationless integer quantum Hall effect occurs as a series of dissipative voltage steps. A mechanism…
