Gradient RG Flow in Scalar-Fermion QFTs
William H. Pannell, William Patrick Ronayne, Andreas Stergiou
The gradient property of the renormalisation group (RG) is examined to four-loop order in scalar-fermion systems in and dimensions. The crucial role played…

Magnetised Bounds for Conformal Field Theories
Christopher P. Herzog, William H. Pannell, Biswajit Sahoo +1
Aspects of parity-preserving, charge-conjugation-invariant, three-dimensional conformal field theories (CFTs) with a global symmetry in the presence of a background magnetic…

Gradient Flows and the Curvature of Theory Space
William H. Pannell, Andreas Stergiou
The metric and potential associated with the gradient property of renormalisation group flow in multiscalar models in dimensions are studied. The metric is identi…
