A bstractWe 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 $ {{\mathbb{Z}}_2} $ 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… Expand

Bootstrapping the 3d Ising twist defect
A bstractRecent numerical results point to the existence of a conformally invariant twist defect in the critical 3d Ising model. In this note we show that this fact is supported by both epsilonExpand

A structural test for the conformal invariance of the critical 3d Ising model
How can a renormalization group fixed point be scale invariant without being conformal? Polchinski (1988) showed that this may happen if the theory contains a virial current — a non-conserved vectorExpand

This work investigates several three-dimensional lattice models believed to be in the Ising universality class by means of Monte Carlo methods and finite-size scaling, and analyzes all the data simultaneously such that the universal parameters occur only once, leading to an improved accuracy.
