Line defects in the 3d Ising model
read the original abstract
We investigate the properties of the twist line defect in the critical 3d Ising model using Monte Carlo simulations. In this model the twist line defect is the boundary of a surface of frustrated links or, in a dual description, the Wilson line of the Z2 gauge theory. We test the hypothesis that the twist line defect flows to a conformal line defect at criticality and evaluate numerically the low-lying spectrum of anomalous dimensions of the local operators which live on the defect as well as mixed correlation functions of local operators in the bulk and on the defect.

Criticality on R\'enyi defects at (2+1)$d$ O(3) quantum critical points
Numerical evidence shows multiple Rényi defect universality classes at O(3) quantum critical points depending on entanglement cut type, with a possible phase transition on the defect for extraordinary cuts as the Rény...

Crosscap Defects
Crosscap defects from Z2 spacetime quotients in CFTs yield new crossing equations and O(N) model examples without displacement or tilt operators, forming defect conformal manifolds lacking exactly marginal operators.
