Dynamics of a Fermi gas quenched to unitarity
P. Dyke, A. Hogan, I. Herrera +3
We present an experimental study of a two component Fermi gas following an interaction quench into the superfluid phase. Starting with a weakly attractive gas in the normal phase,…
High Frequency Sound in a Unitary Fermi Gas
C. C. N. Kuhn, S. Hoinka, I. Herrera +4
We present an experimental and theoretical study of the phonon mode in a unitary Fermi gas. Using two-photon Bragg spectroscopy, we measure excitation spectra at a momentum of appr…
Contact and sum-rules in a near-uniform Fermi gas at unitarity
C. Carcy, S. Hoinka, M. G. Lingham +4
We present an experimental study of the high-energy excitation spectra of unitary Fermi gases. Using focussed beam Bragg spectroscopy, we locally probe atoms in the central region…
Quantum anomaly and 2D-3D crossover in strongly interacting Fermi gases
T. Peppler, P. Dyke, M. Zamorano +2
We present an experimental investigation of collective oscillations in harmonically trapped Fermi gases through the crossover from two to three dimensions. Specifically, we measure…
Goldstone mode and pair-breaking excitations in atomic Fermi superfluids
Sascha Hoinka, Paul Dyke, Marcus G. Lingham +3
Spontaneous symmetry breaking is a central paradigm of elementary particle physics, magnetism, superfluidity and superconductivity. According to Goldstone's theorem, phase transiti…
Precise determination of the structure factor and contact in a unitary Fermi gas
Sascha Hoinka, Marcus Lingham, Kristian Fenech +4
We present a high-precision determination of the universal contact parameter in a strongly interacting Fermi gas. In a trapped gas at unitarity we find the contact to be $3.06 \pm…
