Line defect correlators in fermionic CFTs
Julien Barrat, Pedro Liendo, Philine van Vliet
Scalar-fermion models, such as the Gross-Neveu-Yukawa model, admit natural defects given by the exponential of a scalar field integrated along a straight line. In $4-\varepsil…
Multipoint correlators on the supersymmetric Wilson line defect CFT II: Unprotected operators
Julien Barrat, Pedro Liendo, Giulia Peveri
We continue our study of multipoint correlators of scalar fields on the defect CFT generated by inserting operators along the Maldacena-Wilson line in SYM. W…
Bootstrapping line defects with global symmetry
Aleix Gimenez-Grau, Edoardo Lauria, Pedro Liendo +1
We use the numerical bootstrap to study conformal line defects with global symmetry. Our results are very general and capture in particular conformal line defects originatin…
A dispersion relation for defect CFT
Julien Barrat, Aleix Gimenez-Grau, Pedro Liendo
We present a dispersion relation for defect CFT that reconstructs two-point functions in the presence of a defect as an integral of a single discontinuity. The main virtue of this…
Spontaneous breaking of finite group symmetries at all temperatures
Pedro Liendo, Junchen Rong, Haoyu Zhang
We study conformal field theories with finite group symmetries with spontaneous symmetry breaking (SSB) phases that persist at all temperatures. We work with two theories co…
Multipoint correlators on the supersymmetric Wilson line defect CFT
Julien Barrat, Pedro Liendo, Giulia Peveri +1
We study multipoint correlators of protected scalars on the Maldacena-Wilson line in SYM. Working at weak coupling in the planar limit, we derive an explicit recurs…
