General Four-Loop Beta Function for Scalar-Fermion Theories in Three Dimensions

York SchrÃ¶der, Emmanuel Stamou, Tom Steudtner +1

We present general four-loop template $I^^{2}$ -functions and anomalous field dimensions for renormalisable scalar-fermion theories in three dimensions. By imposing $N = 1$ and…

Revisiting the $I ¨ ^{6}$ Theory in Three Dimensions at Large $N$

Sandra KvedaraitÄ, Tom Steudtner, Max Uetrecht

We investigate the $O (N)$ --symmetric $I ¨ ^{6}$ theory in three spacetime dimensions using dimensional regularisation and minimal subtraction. The predictions of other methods are scru…

Quantum multicriticality and emergent symmetry in Dirac systems with two order parameters at three-loop order

Max Uetrecht, Igor F. Herbut, Michael M. Scherer +2

Two-dimensional materials with interacting Dirac excitations can host quantum multicritical behavior near the phase boundaries of the semimetallic and two-ordered phases. We study…
