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…
Magnetised Bounds for Conformal Field Theories
Christopher P. Herzog, William H. Pannell, Biswajit Sahoo +1
Aspects of parity-preserving, three-dimensional conformal field theories (CFTs) with a global symmetry in the presence of a background magnetic field are investigated. A loc…
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…
A Nonlocal Schwinger Model
Ludovic Fraser-Taliente, Christopher P. Herzog, Abhay Shrestha
We solve a system of massless fermions constrained to two space-time dimensions interacting via a space-time dimensional Maxwell field. Through dimensional reduction to the def…
An Interacting, Higher Derivative, Boundary Conformal Field Theory
Christopher P. Herzog, Yanjun Zhou
We consider a higher derivative scalar field theory in the presence of a boundary and a classically marginal interaction. We first investigate the free limit where the scalar obeys…
