Quantum Pumping with Ultracold Atoms on Microchips: Fermions versus Bosons
Abstract
We present a design for simulating quantum pumping of electrons in a mesoscopic circuit with ultra-cold atoms in a micro-magnetic chip trap. We calculate theoretical results for quantum pumping of both bosons and fermions, identifying differences and common features, including geometric behavior and resonance transmission. We analyze the feasibility of experiments with bosonic 87Rb and fermionic 40K atoms with an emphasis on reliable atomic current measurements.
