Defects in conformal field theory [PDF]
Journal of High Energy Physics, 2016 A bstractWe 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 presence of the defect.

Geometry of complexity in conformal field theory [PDF]
Physical Review Research, 2020 We initiate quantitative studies of complexity in (1+1)-dimensional conformal field theories with a view that they provide the simplest setting to find a gravity dual to complexity.

Decoherence in Conformal Field Theory [PDF]
Journal of High Energy Physics, 2020 Noise sources are ubiquitous in Nature and give rise to a description of quantum systems in terms of stochastic Hamiltonians. Decoherence dominates the noise-averaged dynamics and leads to dephasing and the decay of coherences in the eigenbasis of the ...

State-operator correspondence in celestial conformal field theory [PDF]
Journal of High Energy Physics, 2021 The bulk-to-boundary dictionary for 4D celestial holography is given a new entry defining 2D boundary states living on oriented circles on the celestial sphere.

Light-ray operators in conformal field theory [PDF]
Journal of High Energy Physics, 2018 We argue that every CFT contains light-ray operators labeled by a continuous spin J. When J is a positive integer, light-ray operators become integrals of local operators over a null line.

Conformal field theory complexity from Euler-Arnold equations [PDF]
Journal of High Energy Physics, 2020 Defining complexity in quantum field theory is a difficult task, and the main challenge concerns going beyond free models and associated Gaussian states and operations.

Hecke relations in rational conformal field theory [PDF]
Journal of High Energy Physics, 2018 We define Hecke operators on vector-valued modular forms of the type that appear as characters of rational conformal field theories (RCFTs). These operators extend the previously studied Galois symmetry of the modular representation and fusion algebra of

Quantum gravity from conformal field theory [PDF]
Journal of High Energy Physics, 2018 We bootstrap loop corrections to AdS5 supergravity amplitudes by enforcing the consistency of the known classical results with the operator product expansion of N $$ \mathcal{N} $$ = 4 super Yang-Mills theory.

Genus-one string amplitudes from conformal field theory [PDF]
Journal of High Energy Physics, 2019 We explore and exploit the relation between non-planar correlators in N $$ \mathcal{N} $$ = 4 super-Yang-Mills, and higher-genus closed string amplitudes in type IIB string theory.

Entanglement entropy and conformal field theory [PDF]
Journal of Physics A: Mathematical and Theoretical, 2009 We review the conformal field theory approach to entanglement entropy in 1+1 dimensions. We show how to apply these methods to the calculation of the entanglement entropy of a single interval, and the generalization to different situations such as finite
