Scalar-Fermion Fixed Points in the Expansion
William H. Pannell, Andreas Stergiou
The one-loop beta functions for systems of scalars and fermions interacting via a general potential are analysed as tensorial equations in dimensions. T…
Line Defect RG Flows in the Expansion
William H. Pannell, Andreas Stergiou
A general analysis of line defect renormalisation group (RG) flows in the expansion below dimensions is undertaken. The defect beta function for general scalar-…
Boundaries in Free Higher Derivative Conformal Field Theories
Adam Chalabi, Christopher P. Herzog, Krishnendu Ray +3
We consider free higher derivative theories of scalars and Dirac fermions in the presence of a boundary in general dimension. We establish a method for finding consistent conformal…
CFTs with Global Symmetry in 3D and the Chiral Phase Transition of QCD
Stefanos R. Kousvos, Andreas Stergiou
Conformal field theories (CFTs) with global symmetry in dimensions have been studied for years due to their potential relevance to the chiral phase transiti…
Weyl Covariance and the Energy Momentum Tensors of Higher-Derivative Free Conformal Field Theories
Andreas Stergiou, Gian Paolo Vacca, Omar Zanusso
Energy momentum tensors of higher-derivative free scalar conformal field theories in flat spacetime are discussed. Two algorithms for the computation of energy momentum tensors are…
Bootstrapping Mixed MN Correlators in 3D
Stefanos R. Kousvos, Andreas Stergiou
The recent emergence of the modern conformal bootstrap method for the study of conformal field theories (CFTs) has enabled the revisiting of old problems in classical critical phen…
