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 …

Bootstrability in line-defect CFTs with improved truncation methods

V Niarchos, C Papageorgakis, P Richmond… - Physical Review D, 2023 - APS
We study the conformal bootstrap of 1D CFTs on the straight Maldacena–Wilson line in 4D
N= 4 super-Yang–Mills theory. We introduce an improved truncation scheme with an “OPE …

Holographic cameras: an eye for the bulk

S Caron-Huot - Journal of High Energy Physics, 2023 - Springer
A bstract We consider four-point correlators in an excited quantum state of a field theory. We
show that, when the theory and state are holographic, a judiciously applied Fourier …

Sum rules & Tauberian theorems at finite temperature

E Marchetto, A Miscioscia, E Pomoni - Journal of High Energy Physics, 2024 - Springer
A bstract We study CFTs at finite temperature and derive explicit sum rules for one-point
functions of operators by imposing the KMS condition and we explicitly estimate one-point …

Spectrum continuity and level repulsion: the Ising CFT from infinitesimal to finite ε

J Henriksson, SR Kousvos, M Reehorst - Journal of High Energy Physics, 2023 - Springer
A bstract Using numerical conformal bootstrap technology we perform a non-perturbative
study of the Ising CFT and its spectrum from infinitesimal to finite values of ε= 4–d. Exploiting …

Analytic bootstrap of mixed correlators in the O (n) CFT

F Bertucci, J Henriksson, B McPeak - Journal of High Energy Physics, 2022 - Springer
A bstract We use large spin perturbation theory and the Lorentzian inversion formula to
compute order-ϵ corrections to mixed correlators in the O (n) Wilson-Fisher CFT in 4− ϵ …

Skydiving to bootstrap islands

A Liu, D Simmons-Duffin, N Su… - arxiv preprint arxiv …, 2023 - arxiv.org
We study families of semidefinite programs (SDPs) that depend nonlinearly on a small
number of" external" parameters. Such families appear universally in numerical bootstrap …

Easy bootstrap for the 3D Ising model

W Li - arxiv preprint arxiv:2312.07866, 2023 - arxiv.org
As a simple lattice model that exhibits a phase transition, the Ising model plays a
fundamental role in statistical and condensed matter physics. Its continuum limit also …

Easy bootstrap for the 3D Ising model: a hybrid approach of the lightcone bootstrap and error minimization methods

W Li - Journal of High Energy Physics, 2024 - Springer
A bstract As a simple lattice model that exhibits a phase transition, the Ising model plays a
fundamental role in statistical and condensed matter physics. The Ising transition is realized …

Comb Channel Lightcone Bootstrap II: Triple-Twist Anomalous Dimensions

S Harris, A Kaviraj, JA Mann, L Quintavalle… - arxiv preprint arxiv …, 2024 - arxiv.org
We advance the multipoint lightcone bootstrap and compute anomalous dimensions of triple-
twist operators at large spin. In contrast to the well-studied double-twist operators, triple-twist …
