Fermions and the Renormalisation Group at Large N
Charlie Cresswell-Hogg, Daniel F. Litim
We investigate fermionic quantum field theories using functional renormalisation. In the limit of many fermion flavours , we demonstrate that theories have exact solutions for t…

Dilaton Physics from Asymptotic Freedom
Charlie Cresswell-Hogg, Daniel F. Litim, Roman Zwicky
The dilaton is investigated from first principles in an asymptotically free Gross-Neveu-Yukawa theory in three dimensions. In the limit of many fermion flavours, the theory feature…
