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 …

New developments in the numerical conformal bootstrap

S Rychkov, N Su - Reviews of Modern Physics, 2024 - APS
Over the past 15 years, the numerical conformal bootstrap has become an indispensable
tool for studying strongly coupled conformal field theories in various dimensions. Reviewed …

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 semidefinite program solver for the conformal bootstrap

D Simmons-Duffin - Journal of High Energy Physics, 2015 - Springer
A bstract We introduce SDPB: an open-source, parallelized, arbitrary-precision semidefinite
program solver, designed for the conformal bootstrap. SDPB significantly outperforms less …

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 …

The Gross-Neveu-Yukawa archipelago

RS Erramilli, LV Iliesiu, P Kravchuk, A Liu… - Journal of High Energy …, 2023 - Springer
