Asymptotic safety of scalar field theories
Daniel F. Litim, Matthew J. Trott
We study symmetric scalar field theories using Polchinski's renormalisation group. In the infinite limit the model is solved exactly including at strong coupling. A…

Non-Fermi liquid fixed points and anomalous Landau damping in a quantum critical metal
Matthew J. Trott, Chris A. Hooley
We present a functional renormalization group calculation of the properties of a quantum critical metal in spatial dimensions. Our theory describes a general class of Pomeran…
