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…
The beginning of the endpoint bootstrap for conformal line defects
Ryan A. Lanzetta, Shang Liu, Max A. Metlitski
A challenge in the study of conformal field theory (CFT) is to characterize the possible defects in specific bulk CFTs. Given the success of numerical bootstrap techniques applied…
Bootstrapping the Quantum Hall problem
Qiang Gao, Ryan A. Lanzetta, Patrick Ledwith +2
The bootstrap method aims to solve problems by imposing constraints on the space of physical observables, which often follow from physical assumptions such as positivity and symmet…
