Functional renormalisation group for quantum critical metals in d=2 — •Matthew Trott and Chris Hooley — SUPA, School of Physics and Astronomy, University of St Andrews, North Haugh, St Andrews, Fife, KY16 9SS, United Kingdom

We present a novel functional renormalisation group calculation for quantum critical metals in two spatial dimensions. We utilise soft frequency regulators to stop the suppression of particle-hole excitations in an attempt to consistently describe Landau damping and non-Fermi liquid effects. Additionally we track bosonic interactions up to sextic coupling to elucidate the fixed point structure.
