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…
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…
Thermodynamics of an attractive 2D Fermi gas
K. Fenech, P. Dyke, T. Peppler +4
Thermodynamic properties of matter are conveniently expressed as functional relations between variables known as equations of state. Here we experimentally determine the compressib…
Criteria for 2D kinematics in an interacting Fermi gas
P. Dyke, K. Fenech, T. Peppler +7
Ultracold Fermi gases subject to tight transverse confinement offer a highly controllable setting to study the two-dimensional (2D) BCS to Berezinskii-Kosterlitz-Thouless superflui…
Local observation of pair-condensation in a Fermi gas at unitarity
M. G. Lingham, K. Fenech, S. Hoinka +1
We present measurements of the local (homogeneous) density-density response function of a Fermi gas at unitarity using spatially resolved Bragg spectroscopy. By analyzing the Bragg…
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…
