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…

The unitary Fermi gas at large charge and large N
Simeon Hellerman, Daniil Krichevskiy, Domenico Orlando +3
We study the unitary Fermi gas in a harmonic trapping potential starting from a microscopic theory in the limit of large charge and large number of fermion flavors N. In this regim…

Integrability of Large-Charge Sectors in Generic 2D EFTs
Matthew Dodelson, Simeon Hellerman, Masataka Watanabe +1
It is shown that integrability is an accidental property of generic two-dimensional -symmetric asymptotically-free theories in the regime where the charge density is much lar…
