Infinite Heat Order in 3+1 Dimensions
Borut Bajc, Giulia Muco, Francesco Sannino +1
We investigate whether spontaneous symmetry breaking can persist up to arbitrarily high temperature in ultraviolet-complete quantum field theories in four spacetime dimensions. We…
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…
Four-Fermion Deformations on Line Defects in QED with Yukawas
Alessandra D'Alise, Giulia Muco, Francesco Sannino
We elucidate the dynamics induced by a Wilson Line of charge and electron charge in coupled to a real scalar via Yukawa interactions. We observe that there is a ran…
