PT symmetry breaking and exceptional points for a class of inhomogeneous complex potentials
Patrick Dorey, Clare Dunning, Anna Lishman +1
We study a three-parameter family of PT-symmetric Hamiltonians, related via the ODE/IM correspondence to the Perk-Schultz models. We show that real eigenvalues merge and become com…

Reflection factors and exact g-functions for purely elastic scattering theories
Patrick Dorey, Anna Lishman, Chaiho Rim +1
We discuss reflection factors for purely elastic scattering theories and relate them to perturbations of specific conformal boundary conditions, using recent results on exact off-c…
