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 …

The conformal bootstrap

D Poland, D Simmons-Duffin - Nature Physics, 2016 - nature.com
The conformal bootstrap was proposed in the 1970s as a strategy for calculating the
properties of second-order phase transitions. After spectacular success elucidating two …

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 …

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 …

The 3d stress-tensor bootstrap

A Dymarsky, F Kos, P Kravchuk, D Poland… - Journal of High Energy …, 2018 - Springer
A bstract We study the conformal bootstrap for 4-point functions of stress tensors in parity-
preserving 3d CFTs. To set up the bootstrap equations, we analyze the constraints of …

Unitarity violation at the Wilson-Fisher fixed point in dimensions

M Hogervorst, S Rychkov, BC van Rees - Physical Review D, 2016 - APS
We consider the continuation of free and interacting scalar field theory to noninteger
spacetime dimension d. We find that the correlation functions in these theories are …

Bootstrapping 3D fermions with global symmetries

L Iliesiu, F Kos, D Poland, SS Pufu… - Journal of High Energy …, 2018 - Springer
A bstract We study the conformal bootstrap for 4-point functions of fermions< ψ i ψ j ψ k ψ ℓ>
in parity-preserving 3d CFTs, where ψ i transforms as a vector under an O (N) global …

The M-theory archipelago

NB Agmon, SM Chester, SS Pufu - Journal of High Energy Physics, 2020 - Springer
A bstract We combine supersymmetric localization results and the numerical conformal
bootstrap technique to study the 3d maximally supersymmetric (\(\mathcal {N}\)= 8) CFT on N …
