Many-body Physics in Two-dimensional Fermi Gases

Abstract

Optically-trapped, strongly-interacting Fermi gases are models for exotic strongly interacting systems in nature. For this reason, tabletop experiments with strongly interacting atomic Fermi gases can provide measurements that are relevant to all strongly-interacting Fermi systems, thus impacting theories in intellectual disciplines outside atomic physics, including materials science and condensed matter physics (superconductivity), nuclear physics (nuclear matter), high-energy physics (effective theories of the strong interactions), astrophysics (compact stellar objects), the physics of quark-gluon plasmas (elliptic flow), and most recently, string-theory (minimum viscosity hydrodynamics, non-equilibrium dynamics, and scale invariant non-relativistic systems). This program explores a strongly-interacting Fermi gas of 6Li atoms, confined in quasi-two-dimensional pancake geometries, simulating layered materials. We have extended our work to include new studies of Fermi gases in the extreme, weakly interacting regime, near the zero crossing of the scattering length below a broad Feshbach resonance, where spin-energy correlation naturally emerges.
