Strongly Correlated Fermi Systems in Two-Dimensional Triangular and Honeycomb Lattices

Abstract

This research project aimed to study strongly correlated Fermi gases which result from confinement of the gases in a 2Dlattice. The presence of the lattice partitions the gas into an ensemble of one-dimensional Fermi gases which, due to Fermisurface nesting in 1D, are predicted to become highly correlated even for weak interactions which gives rise to spin-chargeseparation at zero temperature. Attempts to observe spin-charge separation were compromised by the finite temperature ofthe gas. However, new discoveries were made regarding the suppression of inelastic collisions in 1D near p-wave Feshbachresonances. This may permit the study of p-wave superfluidity in a dilute 1D gas of neutral atoms.
