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…
