Eye-opening bounds on cusps
Ryan A. Lanzetta, Ian Moult, Yifan Wang
We derive new nonperturbative inequalities on the cusp anomalous dimensions of conformal line defects. We impose reflection positivity, locality, and conformal invariance on a pair…
Cutting corners: exciting and magical bounds from the cusp bootstrap
Ryan A. Lanzetta, Ian Moult, Yifan Wang
An illuminating probe of the dynamics of a line defect is the global geometry of its worldline. For a conformal line defect in a conformal field theory, sharp corners in the worldl…
Fortuitous Universality of Bose-Kondo Impurities
Abhijat Sarma, Zheng Zhou, Ryan A. Lanzetta +1
We use the fuzzy-sphere approach to study the Bose-Kondo impurity problem, namely a spin- impurity coupled to the -dimensional Wilson-Fisher CFT (Heisenberg univer…
Self-dual Higgs transitions: Toric code and beyond
Wenjie Ji, Ryan A. Lanzetta, Zheng Zhou +1
The toric code, when deformed in a way that preserves the self-duality symmetry exchanging the electric and magnetic excitations, admits a transition to a topologica…
