Journal ArticleDOI
A Mellin space approach to the conformal bootstrap
TL;DR: The conformal bootstrap as mentioned in this paper uses the Mellin representation of CFT functions and expands them in terms of crossing symmetric combinations of AdS and Witten exchange functions in order to cancel spurious powers in position space.
Journal ArticleDOI
Conformal Bootstrap in Mellin Space
TL;DR: This work proposes a new approach towards analytically solving for the dynamical content of conformal field theories (CFTs) using the bootstrap philosophy, and illustrates the power of this method in the ε expansion of the Wilson-Fisher fixed point by reproducing anomalous dimensions and obtaining OPE coefficients to higher orders in ε than currently available using other analytic techniques.
Journal ArticleDOI
Analytic bootstrap at large spin
TL;DR: In this paper, the anomalous dimensions and OPE coefficients for large spin operators in general conformal field theories in four dimensions containing a scalar operator of conformal dimension Δ¯¯¯¯ ϕ¯¯¯¯.
Journal ArticleDOI
Universal anomalous dimensions at large spin and large twist
TL;DR: In this article, the anomalous dimensions of double trace operators at large spin (l) and large twist (τ) in CFTs in arbitrary dimensions (d ≥ 3) were derived using analytic conformal bootstrap methods.
Journal ArticleDOI
A strongly coupled anisotropic fluid from dilaton driven holography
TL;DR: In this article, the authors considered a system consisting of 5-dimensional gravity with a negative cosmological constant coupled to a massless scalar, the dilaton, and constructed a black brane solution which arises when the system satisfies linearly varying boundary conditions in the asymptotically AdS 5 region.
