Four Fermi Theory in Four Dimensions is Renormalisable
Charlie Cresswell-Hogg, Daniel F. Litim
We demonstrate the renormalisability of quantum field theories in four dimensions with elementary self-interacting Dirac fermions and to leading order in the limit of many fermion…
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…
Fermion Mass Generation without Symmetry Breaking
Charlie Cresswell-Hogg, Daniel F. Litim
We study the generation of fermion mass in a context where interactions break a discrete chiral symmetry. Then, fermion mass is not protected by a symmetry, no symmetry is broken b…
Scale symmetry breaking and generation of mass at quantum critical points
Charlie Cresswell-Hogg, Daniel F. Litim
We study an asymptotically free theory of relativistic Dirac fermions and a real scalar field coupled by Yukawa and scalar self-interactions in three dimensions using functiona…
Critical Fermions with Spontaneously Broken Scale Symmetry
Charlie Cresswell-Hogg, Daniel F. Litim
We study relativistic fermions in three euclidean dimensions with four- and six-fermion interactions of the Gross-Neveu type. In the limit of many fermion flavors, and besides the…
