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…
Semiclassics at the cusp
Jahmall Bersini, Domenico Orlando, Susanne Reffert +1
We study cusped Wilson line operators in the Abelian Higgs model in at large external charges. Using a double-scaling limit , with …
Asymptotics in the bi-Yang-Baxter Sigma Model
Meer Ashwinkumar, Domenico Orlando, Susanne Reffert +1
Working in a sector of large charge is a powerful tool to analytically access models that are either strongly coupled or otherwise difficult to solve explicitly. In the context of…
Resurgence Analysis of the Nambu-Jona-Lasinio model at large charge
Jahmall Bersini, Simeon Hellerman, Domenico Orlando +1
We study the fixed point of the three-dimensional NJL model in a double-scaling limit where both the charge and the number of fermion flavors become large with a fixed rati…
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…
