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…
Extraordinary Surface Criticalities for Interacting Fermions
Oleksandr Diatlyk, Zimo Sun, Yifan Wang
Interacting fermions exhibit a rich landscape of surface defects and associated critical phenomena. We investigate novel surface critical behavior in the three-dimensional Gross-Ne…
Factorizing Defects from Generalized Pinning Fields
Fedor K. Popov, Yifan Wang
We introduce generalized pinning fields in conformal field theory that model a large class of critical impurities at large distance, enriching the familiar universality classes. We…
Surprises in the Ordinary: Invariant Surface Defect in the -expansion
Oleksandr Diatlyk, Zimo Sun, Yifan Wang
We study an invariant surface defect in the Wilson-Fisher conformal field theory (CFT) in dimensions. This defect is defined by mass deformation on a two-dimensional…
Effective Field Theory of Conformal Boundaries
Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1
We introduce an effective field theory (EFT) for conformal impurity by considering a pair of transversely displaced impurities and integrating out modes with mass inversely proport…
Defect Fusion and Casimir Energy in Higher Dimensions
Oleksandr Diatlyk, Himanshu Khanchandani, Fedor K. Popov +1
We study the operator algebra of extended conformal defects in more than two spacetime dimensions. Such algebra structure encodes the combined effect of multiple impurities on phys…
Gauging Non-Invertible Symmetries: Topological Interfaces and Generalized Orbifold Groupoid in 2d QFT
Oleksandr Diatlyk, Conghuan Luo, Yifan Wang +1
Gauging is a powerful operation on symmetries in quantum field theory (QFT), as it connects distinct theories and also reveals hidden structures in a given theory. We initiate a sy…
Beyond in Large Conformal Vector Models at Finite Temperature
Oleksandr Diatlyk, Fedor K. Popov, Yifan Wang
We investigate finite-temperature observables in three-dimensional large critical vector models taking into account the effects suppressed by . Such subleading contri…
