Precision thermodynamics of the strongly interacting Fermi gas in two dimensions
S. Ramachandran, S. Jensen, Y. Alhassid
The two-species cold atomic Fermi gas with attractive short-range interactions in two spatial dimensions undergoes a Bardeen-Cooper-Schrieffer (BCS) to a Bose-Einstein Condensate (…
Precision Thermodynamics of the Fermi polaron at strong coupling
S. Ramachandran, S. Jensen, Y. Alhassid
The Fermi polaron problem, which describes a mobile impurity that interacts with a spin-polarized Fermi sea, is a paradigmatic system in quantum many-body physics and has been chal…
Pseudogap regime of the unitary Fermi gas with lattice auxiliary-field quantum Monte Carlo in the continuum limit
S. Jensen, C. N. Gilbreth, Y. Alhassid
The unitary Fermi gas (UFG) is a strongly correlated system of two-species (spin-1/2) fermions with a short-range attractive interaction modeled by a contact interaction and has at…
The contact in the unitary Fermi gas across the superfluid phase transition
S. Jensen, C. N. Gilbreth, Y. Alhassid
A quantity known as the contact plays a fundamental role in quantum many-body systems with short-range interactions. The determination of the temperature dependence of the contact…
The pseudogap regime in the unitary Fermi gas
S. Jensen, C. N. Gilbreth, Y. Alhassid
We discuss the pseudogap regime in the cold atomic unitary Fermi gas, with a particular emphasis on the auxiliary-field quantum Monte Carlo (AFMC) approach. We discuss possible sig…
Pairing correlations across the superfluid phase transition in the unitary Fermi gas
S. Jensen, C. N. Gilbreth, Y. Alhassid
In the two-component Fermi gas with a contact interaction, a pseudogap regime can exist at temperatures between the superfluid critical temperature and a temperature $T^* > T…
