Nonperturbative infrared finiteness in super-renormalisable scalar quantum field theory
Guido Cossu, Luigi Del Debbio, Andreas Juttner +5
We present a study of the IR behaviour of a three-dimensional super-renormalisable quantum field theory (QFT) consisting of a scalar field in the adjoint of with a in…

Renormalization of the energy-momentum tensor in three-dimensional scalar theories using the Wilson flow
Luigi Del Debbio, Elizabeth Dobson, Andreas Jüttner +6
A nonperturbative determination of the energy-momentum tensor is essential for understanding the physics of strongly coupled systems. The ability of the Wilson flow to eliminate di…
