Quantum reflection of ultracold atoms from thin films, graphene, and semiconductor heterostructures
T. E. Judd, R. G. Scott, A. M. Martin +2
We show that thin dielectric films can be used to enhance the performance of passive atomic mirrors by enabling quantum reflection probabilities of over 90% for atoms incident at v…

Atom chips with two-dimensional electron gases: theory of near surface trapping and ultracold-atom microscopy of quantum electronic systems
G. Sinuco-León, B. Kaczmarek, P. Krüger +1
We show that current in a two-dimensional electron gas (2DEG) can trap ultracold atoms m away with orders of magnitude less spatial noise than a metal trapping wire. This ena…
