Strongly Interacting Fermi Gases In Two Dimensions

Abstract

In this project we aim to directly realize a model system of strongly correlated electrons moving in two dimensions using ultracold fermionic atoms stored in a sheet of light. The goal is to create high-temperature superfluids in two dimensions, to establish interferometry and magnetometry with these systems, and to study the phase diagram of two-dimensional Fermi gases with arbitrary interactions and spin imbalance. Fast rotation will mimic high magnetic fields and allow the approach to the Quantum Hall regime. The system shares traits with High-Tc materials, where super currents flow between stacks of weakly connected two dimensional planes. This year has seen rather spectacular progress where transport of Fermions has been studied, in work that we published in Nature. Recently, we were able to study the evolution of fermion pairing from three to two dimensions.
