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.

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

On non-supersymmetric conformal manifolds: field theory and holography [PDF]
Journal of High Energy Physics, 2017 We discuss the constraints that a conformal field theory should enjoy to admit exactly marginal deformations, i.e. to be part of a conformal manifold. In particular, using tools from conformal perturbation theory, we derive a sum rule from which one can ...

Loops in AdS from conformal field theory [PDF]
Journal of High Energy Physics, 2017 We propose and demonstrate a new use for conformal field theory (CFT) crossing equations in the context of AdS/CFT: the computation of loop amplitudes in AdS, dual to non-planar correlators in holographic CFTs. Loops in AdS are largely unexplored, mostly

Discreteness and integrality in Conformal Field Theory [PDF]
Journal of High Energy Physics, 2021 Various observables in compact CFTs are required to obey positivity, discreteness, and integrality. Positivity forms the crux of the conformal bootstrap, but understanding of the abstract implications of discreteness and integrality for the space of CFTs

On marginal operators in boundary conformal field theory [PDF]
Journal of High Energy Physics, 2019 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 operator of protected scaling dimension ∆ equal to the space-time dimension d ...

On the Real Part of a Conformal Field Theory [PDF]
Universe, 2018 Every conformal field theory has the symmetry of taking each field to its adjoint. We consider here the quotient (orbifold) conformal field theory obtained by twisting with respect to this symmetry.

Krylov complexity in conformal field theory [PDF]
Physical Review D, 2021 Krylov complexity, or K-complexity for short, has recently emerged as a new probe of chaos in quantum systems. It is a measure of operator growth in Krylov space, which conjecturally bounds the operator growth measured by the out of time ordered ...

Numerical Evidence for a Haagerup Conformal Field Theory. [PDF]
Physical Review Letters, 2021 We numerically study an anyon chain based on the Haagerup fusion category and find evidence that it leads in the long-distance limit to a conformal field theory whose central charge is ∼2.

Global symmetry and conformal bootstrap in the two-dimensional $Q$-state Potts model
SciPost Physics, 2023 The Potts conformal field theory is an analytic continuation in the central charge of conformal field theory describing the critical two-dimensional $Q$-state Potts model.
