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 $<1\mu$m away with orders of magnitude less spatial noise than a metal trapping wire. This ena…
