Non-invertible symmetries and selection rules for RG flows of coset models
Valentin Benedetti, Paul Fendley, Javier M. Magan
We analyze superselection sectors, non-invertible symmetries and selection rules for RG flows triggered via perturbations of a UV two-dimensional conformal field theory (CFT).…
Perfect Particle Transmission through Duality Defects
Atsushi Ueda, Vic Vander Linden, Laurens Lootens +3
We study wavepackets that propagate across (a) topological interfaces in quantum spin systems exhibiting non-invertible symmetries and (b) duality defects coupling dual theories. W…
Exact solution of a massless scalar field with a relevant boundary interaction
P. Fendley, H. Saleur, N. P. Warner
We solve exactly the "boundary sine-Gordon" system of a massless scalar field ϕwith a \cos[βϕ/2] potential at a boundary. This model has appeared in several contexts, including tun…
Deriving Boundary S Matrices
P. Fendley, H. Saleur
We show how to derive exact boundary matrices for integrable quantum field theories in 1+1 dimensions using lattice regularization. We do this calculation explicitly for the si…
Massless Flows II: the exact S-matrix approach
P. Fendley, H. Saleur, Al. B. Zamolodchikov
We study the spectrum, the massless S-matrices and the ground-state energy of the flows between successive minimal models of conformal field theory, and within the sine-Gordon mode…
N=2 Supersymmetry, Painleve III and Exact Scaling Functions in 2D Polymers
P. Fendley, H. Saleur
We discuss in this paper various aspects of the off-critical model in two dimensions. We find the ground-state energy conjectured by Zamolodchikov for the unitary minimal mo…
