How to get an interacting conformal line defect for free theories
Samuel Bartlett-Tisdall, Dongsheng Ge, Christopher P. Herzog
We argue that interacting conformal line defects in free quantum field theories can exist, provided that inversion symmetry is broken. Important for our demonstration is the existe…

Novel Defect Universality Classes from Interacting RG Interfaces
Samuel Bartlett-Tisdall, Sabine Harribey, William Pannell
We search for new defect universality classes by considering localised interactions placed on an RG interface separating two interacting multiscalar CFTs in dimensi…

An Atlas for 3d Conformal Field Theories with a U(1) Global Symmetry
Samuel Bartlett-Tisdall, Christopher P. Herzog, Vladimir Schaub
We present a collection of numerical bootstrap computations for 3d CFTs with a U(1) global symmetry. We test the accuracy of our method and fix conventions through a computation of…
