Journal ArticleDOI
Laser frequency locking by direct measurement of detuning
Adrian Ratnapala,Chris J. Vale,Andrew White,Michael Harvey,Norman R. Heckenberg,Halina Rubinsztein-Dunlop +5 more
TL;DR: This work presents a new method of laser frequency locking in which the feedback signal is directly proportional to the detuning from an atomic transition, even at detunings many times the natural linewidth of the transition.
Journal ArticleDOI
Molecular Bose-Einstein condensation in a versatile low power crossed dipole trap
J. Fuchs,G. J. Duffy,G. Veeravalli,Paul Dyke,M. Bartenstein,Chris J. Vale,Peter Hannaford,Wayne J. Rowlands +7 more
TL;DR: In this article, Bose-Einstein condensates of 6Li2 molecules were produced in a low power (22 W) crossed optical dipole trap. But they were not shown to have a high degree of flexibility in trapping geometry for studying ultracold Bose gases.
Journal ArticleDOI
High-Frequency Sound in a Unitary Fermi Gas.
Carlos C. N. Kuhn,Sascha Hoinka,Ivan Herrera,Paul Dyke,Jami J. Kinnunen,Georg M. Bruun,Georg M. Bruun,Chris J. Vale +7 more
TL;DR: The study reveals strong similarities between sound propagation in the unitary Fermi gas and bosonic liquid helium and the temperature dependence of the BA phonon is consistent with a theoretical model based on the quasiparticle random phase approximation.
Journal Article
Local observation of pair-condensation in a Fermi gas at unitarity
TL;DR: Measurements of the local (homogeneous) density-density response function of a Fermi gas at unitarity are presented using spatially resolved Bragg spectroscopy and can be adapted to provide any homogeneous parameter satisfying the local density approximation.
Journal ArticleDOI
Bragg spectroscopy of strongly interacting Fermi gases
Marcus Lingham,Kristian Fenech,T. Peppler,Sascha Hoinka,Paul Dyke,Peter Hannaford,Chris J. Vale +6 more
TL;DR: In this article, the authors provide an overview of recent developments and emerging topics in the study of two-component Fermi gases using Bragg spectroscopy, which is achieved by exposing a gas to two intersecting laser beams with a slight frequency difference and measuring the momentum transferred to the atoms.
