Conformal defects from string field theory
(2021-01-01)
Unlike conformal boundary conditions, conformal defects of Virasoro minimal models lack classification. Alternatively to the defect perturbation theory and the truncated conformal space approach, we employ open string field ...
Chiral entanglement in massive quantum field theories in 1+1 dimensions
(Springer, 2019-01-23)
Tinkertoys for the E-7 theory
(Springer, 2018-05-04)
We classify the class S theories of type E-7. These are four-dimensional N = 2 superconformal field theories arising from the compactification of the E-7 (2, 0) theory on a punctured Riemann surface, C. The classification ...
Hexagons and correlators in the fishnet theory
(2019-11-01)
We investigate the hexagon formalism in the planar 4d conformal fishnet theory. This theory arises from N = 4 SYM by a deformation that preserves both conformal symmetry and integrability. Based on this relation, we obtain ...
Nonlocal growth processes and conformal invariance
(IOP PUBLISHING LTDBRISTOL, 2012)
Up to now the raise-and-peel model was the single known example of a one-dimensional stochastic process where one can observe conformal invariance. The model has one parameter. Depending on its value one has a gapped phase, ...
Konishi OPE coefficient at the five loop order
(2018-11-01)
We use the method of asymptotic expansions to study the OPE limit of a fourpoint function of protected operators in N= 4 SYM. We use a new method for evaluating the resulting propagator-type integrals and then extract the ...
All five-loop planar four-point functions of half-BPS operators in N= 4 SYM
(2018-11-01)
We obtain all planar four-point correlators of half-BPS operators in N= 4 SYM up to five loops. The ansatz for the integrand is fixed partially by imposing lightcone OPE relations between different correlators. We then fix ...
Defects in conformal field theory
(2016-04-01)
Abstract: We discuss consequences of the breaking of conformal symmetry by a flat or spherical extended operator. We adapt the embedding formalism to the study of correlation functions of symmetric traceless tensors in the ...
