Breakdown of Fermi liquid description for strongly interacting fermions
Yoav Sagi, Tara E. Drake, Rabin Paudel +2
The nature of the normal state of an ultracold Fermi gas in the BCS-BEC crossover regime is an intriguing and controversial topic. While the many-body ground state remains a conden…
Measurement of the Homogeneous Contact of a Unitary Fermi gas
Yoav Sagi, Tara E. Drake, Rabin Paudel +1
By selectively probing the center of a trapped gas, we measure the local, or homogeneous, contact of a unitary Fermi gas as a function of temperature. Tan's contact, C, is proporti…
Direct observation of the Fermi surface in an ultracold atomic gas
T. E. Drake, Y. Sagi, R. Paudel +3
The ideal (i.e. noninteracting), homogeneous Fermi gas, with its characteristic sharp Fermi surface in the momentum distribution, is a fundamental concept relevant to the behavior…
Evolution of the Normal State of a Strongly Interacting Fermi Gas from a Pseudogap Phase to a Molecular Bose Gas
A. Perali, F. Palestini, P. Pieri +5
Wave-vector resolved radio frequency (rf) spectroscopy data for an ultracold trapped Fermi gas are reported for several couplings at Tc, and extensively analyzed in terms of a pair…
Observation of pseudogap behavior in a strongly interacting Fermi gas
J. P. Gaebler, J. T. Stewart, T. E. Drake +4
Ultracold atomic Fermi gases present an opportunity to study strongly interacting Fermi systems in a controlled and uncomplicated setting. The ability to tune attractive interactio…
Verification of universal relations in a strongly interacting Fermi gas
J. T. Stewart, J. P. Gaebler, T. E. Drake +1
Many-body fermion systems are important in many branches of physics, including condensed matter, nuclear, and now cold atom physics. In many cases, the interactions between fermion…
