The conformal bootstrap: Theory, numerical techniques, and applications

D Poland, S Rychkov, A Vichi - Reviews of Modern Physics, 2019 - APS
Conformal field theories have been long known to describe the fascinating universal physics
of scale invariant critical points. They describe continuous phase transitions in fluids …

[HTML][HTML] Selected topics in analytic conformal bootstrap: A guided journey

A Bissi, A Sinha, X Zhou - Physics Reports, 2022 - Elsevier
This review aims to offer a pedagogical introduction to the analytic conformal bootstrap
program via a journey through selected topics. We review analytic methods which include …

Precision islands in the Ising and O (N) models

F Kos, D Poland, D Simmons-Duffin, A Vichi - Journal of High Energy …, 2016 - Springer
A bstract We make precise determinations of the leading scaling dimensions and operator
product expansion (OPE) coefficients in the 3d Ising, O (2), and O (3) models from the …

Carving out OPE space and precise O (2) model critical exponents

SM Chester, W Landry, J Liu, D Poland… - Journal of High Energy …, 2020 - Springer
A bstract We develop new tools for isolating CFTs using the numerical bootstrap. A “cutting
surface” algorithm for scanning OPE coefficients makes it possible to find islands in high …

The lightcone bootstrap and the spectrum of the 3d Ising CFT

D Simmons-Duffin - Journal of High Energy Physics, 2017 - Springer
We compute numerically the dimensions and OPE coefficients of several operators in the 3d
Ising CFT, and then try to reverse-engineer the solution to crossing symmetry analytically …

Bootstrapping line defects with O (2) global symmetry

A Gimenez-Grau, E Lauria, P Liendo… - Journal of High Energy …, 2022 - Springer
A bstract We use the numerical bootstrap to study conformal line defects with O (2) global
symmetry. Our results are very general and capture in particular conformal line defects …

A Mellin space approach to the conformal bootstrap

R Gopakumar, A Kaviraj, K Sen, A Sinha - Journal of High Energy Physics, 2017 - Springer
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 …

Weight shifting operators and conformal blocks

D Karateev, P Kravchuk, D Simmons-Duffin - Journal of High Energy …, 2018 - Springer
A bstract We introduce a large class of conformally-covariant differential operators and a
crossing equation that they obey. Together, these tools dramatically simplify calculations …

Scaling the semidefinite program solver SDPB

W Landry, D Simmons-Duffin - arXiv preprint arXiv:1909.09745, 2019 - arxiv.org
We present enhancements to SDPB, an open source, parallelized, arbitrary precision
semidefinite program solver designed for the conformal bootstrap. The main enhancement is …
