Novel Defect Universality Classes from Interacting RG Interfaces
Samuel Bartlett-Tisdall, Sabine Harribey, William Pannell
We search for new defect universality classes by considering localised interactions placed on an RG interface separating two interacting multiscalar CFTs in dimensi…

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…

The Intersection between Dual Potential and SL(2) Algebraic Spectral Problems
William H. Pannell
The relation between certain Hamiltonians, known as dual, or partner Hamiltonians, under the transformation has long been used as a method of simpli…
