The odd fermion at the edge: odd-even staggering in the trapped, unitary Fermi gas
Silas R. Beane, Domenico Orlando, Susanne Reffert
We investigate the odd-even staggering in the harmonically-trapped unitary Fermi gas at large particle-number charge . Using both a large- BdG description and a complementary…
Trapping-potential dependence of the unitary Fermi gas at the BCS-BEC crossover
Silas R. Beane, Adèle Le Borgne, Domenico Orlando +1
Cold-atom experiments which measure Fermi-gas properties near unitarity confine fermionic atoms to a region of space using trapping potentials of various shapes. The presence of a…
Universal corrections to the superfluid gap in a cold Fermi gas
Silas R. Beane, Zeno Capatti, Roland C. Farrell
A framework for computing the superfluid gap in an effective field theory (EFT) of fermions interacting via momentum-independent contact forces is developed. The leading universal…
Unnuclear matter at large-charge
Silas R. Beane, Domenico Orlando, Susanne Reffert
The utility of the non-relativistic large-charge EFT for physical systems, and neutron matter in particular, relies on controlled Schrödinger-symmetry breaking deformations due to…
