Anomalies from correlation functions in defect conformal field theory
Christopher P. Herzog, Itamar Shamir
In previous work, we showed that an anomaly in the one point function of marginal operators is related by the Wess-Zumino condition to the Euler density anomaly on a two dimensiona…
How a-type anomalies can depend on marginal couplings
Christopher P. Herzog, Itamar Shamir
Even dimensional defects and boundaries in conformal field theory support type anomalies on their world-volume. We show that the one-point functions of marginal operators, in t…
On Marginal Operators in Boundary Conformal Field Theory
Christopher P. Herzog, Itamar Shamir
The presence of a boundary (or defect) in a conformal field theory allows one to generalize the notion of an exactly marginal deformation. Without a boundary, one must find an oper…
Superconformal Models for Graphene and Boundary Central Charges
Christopher P. Herzog, Kuo-Wei Huang, Itamar Shamir +1
In the context of boundary conformal field theory, we investigate whether the boundary trace anomaly can depend on marginal directions in the presence of supersymmetry. Recently, i…
