Abstract The critical O (N) CFT in spacetime dimensions 2< d< 4 is one of the most important
examples of a conformal field theory, with the Ising CFT at N= 1, 2⩽ d< 4, as a notable …

A bstract Distances in the conformal manifold, the space of CFTs related by marginal
deformations, can be measured in terms of the Zamolodchikov metric. Part of the CFT …

Higher Spin Gravity refers to extensions of gravity including at least one field of spin greater
than two. These extensions are expected to provide manageable models of quantum gravity …

We consider conformal field theories around points of large twist degeneracy. Examples of
this are theories with weakly broken higher spin symmetry and perturbations around …

A bstract We describe in more detail our approach to the conformal bootstrap which uses the
Mellin representation of CFT d four point functions and expands them in terms of crossing …

We propose a new approach towards analytically solving for the dynamical content of
conformal field theories (CFTs) using the bootstrap philosophy. This combines the original …

A bstract Using the fact that flat space with a boundary is related by a Weyl transformation to
anti-de Sitter (AdS) space, one may study observables in boundary conformal field theory …

A bstract Coleman's theorem states that continuous internal symmetries cannot be
spontaneously broken in two-dimensional quantum field theories (QFTs). In this work we …

A bstract We study the two-point function of local operators in the critical O (N) model in the
presence of a magnetic field localized on a line. We use a recently developed conformal …
