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 …
Semiclassical Canovaccio for Composite Operators
Oleg Antipin, Jahmall Bersini, Jacob Hafjall +2
We present a novel semiclassical framework tailored to determine the scaling dimensions of heavy neutral composite operators in conformal field theories (CFTs) which are inaccessib…
Exact Results for the Spectrum of the Ising Conformal Field Theory
Oleg Antipin, Jahmall Bersini, Jacob Hafjall +2
We develop a semiclassical framework to determine scaling dimensions of neutral composite operators in scalar conformal field theories. For the critical Ising theory in $d…
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…
On the -angle physics of QCD under pressure: The strange and isospin phase diagram
Jahmall Bersini, Alessandra D'Alise, Clelia Gambardella +1
We unveil the impact of the -angle on the QCD phase diagram at nonzero isospin and strangeness chemical potentials for three light flavors and different quark mass ratios. We e…
Exact Results for Scaling Dimensions of Neutral Operators in scalar CFTs
Oleg Antipin, Jahmall Bersini, Francesco Sannino
We determine the scaling dimension for the class of composite operators in the theory in taking the double scaling limit and $…
