Analytic thermal bootstrap in momentum space: From thermal OPE to QNMs

Julien Barrat, Deniz N. Bozkurt, Enrico Marchetto +2

We initiate a bootstrap program that relates ultraviolet data, encoded in the thermal OPE, to infrared observables, namely, the low-frequency behavior and quasinormal modes. Starti…

Analytic thermal bootstrap meets holography

Julien Barrat, Deniz N. Bozkurt, Enrico Marchetto +2

We compute thermal holographic correlators by combining their analytic structure with the Kubo-Martin-Schwinger (KMS) condition and multi-stress tensor OPE coefficients determined…

The analytic bootstrap at finite temperature

Julien Barrat, Deniz N. Bozkurt, Enrico Marchetto +2

We propose new universal formulae for thermal two-point functions of scalar operators based on their analytic structure, constructed to manifestly satisfy all the bootstrap conditi…

The thermal bootstrap for the critical O(N) model

Julien Barrat, Enrico Marchetto, Alessio Miscioscia +1

We propose a numerical method to estimate one-point functions and the free-energy density of conformal field theories at finite temperature by solving the Kubo-Martin-Schwinger con…

Perturbative bootstrap of the Wilson-line defect CFT: Bulk-defect-defect correlators

Daniele Artico, Julien Barrat, Yingxuan Xu

We study the correlators of bulk and defect half-BPS operators in Super Yang-Mills theory with a Maldacena-Wilson line defect, focusing on the case involving one bu…

Perturbative bootstrap of the Wilson-line defect CFT: Multipoint correlators

Daniele Artico, Julien Barrat, Giulia Peveri

We study the defect CFT associated with the half-BPS Wilson line in Super Yang-Mills theory in four dimensions. Using a perturbative bootstrap approach, we derive n…

Conformal line defects at finite temperature

Julien Barrat, Bartomeu Fiol, Enrico Marchetto +2

We study conformal field theories at finite temperature in the presence of a temporal conformal line defect, wrapping the thermal circle, akin to a Polyakov loop in gauge theories.…

Line defects in conformal field theory: from weak to strong coupling

Julien Barrat

Conformal field theory finds applications across diverse fields, from statistical systems at criticality to quantum gravity through the AdS/CFT correspondence. These theories are s…
