One point functions in large N vector models at finite chemical potential

JR David, S Kumar - Journal of High Energy Physics, 2025 - Springer
A bstract We evaluate the thermal one point function of higher spin currents in the critical
model of U (N) complex scalars interacting with a quartic potential and the U (N) Gross …

Conformal line defects at finite temperature

J Barrat, B Fiol, E Marchetto, A Miscioscia, E Pomoni - SciPost Physics, 2025 - scipost.org
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 …

Thermal one-point functions and their partial wave decomposition

I Burić, F Russo, V Schomerus, A Vichi - Journal of High Energy Physics, 2024 - Springer
A bstract In this work we address partial wave decompositions of thermal one-point functions
in conformal field theories on S 1× S d− 1. With the help of Casimir differential equations we …

The thermal bootstrap for the critical O (N) model

J Barrat, E Marchetto, A Miscioscia… - arXiv preprint arXiv …, 2024 - arxiv.org
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 …

Black Hole Singularity from OPE

N Čeplak, H Liu, A Parnachev, S Valach - arXiv preprint arXiv:2404.17286, 2024 - arxiv.org
Eternal asymptotically AdS black holes are dual to thermofield double states in the boundary
CFT. It has long been known that black hole singularities have certain signatures in …

Temperature-Resistant Order in 2+ 1 Dimensions

Z Komargodski, FK Popov - arXiv preprint arXiv:2412.09459, 2024 - arxiv.org
High temperatures are typically thought to increase disorder. Here we examine this idea in
Quantum Field Theory in 2+ 1 dimensions. For this sake we explore a novel class of …

Constraints on RG Flows from Protected Operators

F Baume, A Miscioscia, E Pomoni - arXiv preprint arXiv:2409.09006, 2024 - arxiv.org
We consider protected operators with the same conformal dimensions in the ultraviolet and
infrared fixed point. We derive a sum rule for the difference between the two-point function …

The large vector model on

JR David, S Kumar - arXiv preprint arXiv:2411.18509, 2024 - arxiv.org
We develop a method to evaluate the partition function and energy density of a massive
scalar on a 2-sphere of radius $ r $ and at finite temperature $\beta $ as power series in …
