Investigating the BCS-BEC crossover region using ultra-cold fermionic atoms

POSTER

Abstract

Recently, ultra-cold atom experiments have allowed researchers access to the BCS-BEC crossover. Starting with a two-component gas of $^{40}$K atoms cooled to quantum degeneracy, a magnetic field Feshbach resonance is used to create strong, tunable interactions in the gas. We report on recent experiments including the observation of pair-correlated atoms through the atom shot-noise in time-of-flight absorption images.
