Flows in the space of interacting chiral boson theories

S Ebert, C Ferko, C Luke Martin… - Physical Review D, 2024 - APS
We study interacting theories of N left-moving and N¯ right-moving Floreanini-Jackiw
bosons in two dimensions. A parametrized family of such theories is shown to enjoy …

Quantization of the ModMax oscillator

C Ferko, A Gupta, E Iyer - Physical Review D, 2023 - APS
We quantize the ModMax oscillator, which is the dimensional reduction of the modified
Maxwell theory to one spacetime dimension. We show that the propagator of the ModMax …

Nonperturbative aspects of two-dimensional -deformed scalar theory from functional renormalization group

J Liu, J Haruna, M Yamada - Physical Review D, 2024 - APS
We study TT¯-deformed O (N) scalar field theory in two-dimensional spacetime using the
functional renormalization group. We derive the β functions for the couplings in the system …

Linear response of entanglement entropy to in massive QFTs

S Ashkenazi, S Chakraborty, Z Ma… - Journal of High Energy …, 2023 - Springer
A bstract We compute the leading correction to entanglement entropy in\(T\overline {T}\)
deformed massive QFTs. We show that both for massive scalar and Dirac fermion, the …

[PDF][PDF] A systematic approach to correlators in TTˉTTˉ deformed CFTs

S He, Y Sun, J Yin - arXiv preprint arXiv:2310.20516, 2023 - pure.mpg.de
We investigate higher-order corrections to correlators in a general CFT with the double trace
TT deformation. Traditional perturbation theory proves inadequate for addressing this issue …

Renormalization in -deformed nonintegrable theories

S Chakrabarti, A Manna, M Raman - Physical Review D, 2022 - APS
That the exact quantum S-matrix of TT¯-deformed field theories is known has interesting
consequences for their perturbative renormalization. Recent investigations into the interplay …

Genus two correlation functions in CFTs with deformation

S He, YZ Li - Science China Physics, Mechanics & Astronomy, 2023 - Springer
Since the definition of TT¯ deformation in the curved Riemann surface is obstructive in the
literature, we propose a way to do the deformation in the genus two Riemann surfaces by …

Field theory of interacting boundary gravitons

S Ebert, E Hijano, P Kraus, R Monten, RM Myers - SciPost Physics, 2022 - scipost.org
Pure three-dimensional gravity is a renormalizable theory with two free parameters labelled
by $ G $ and $\Lambda $. As a consequence, correlation functions of the boundary stress …

Modular transformations of on-shell actions of (root-) deformed holographic CFTs

J Tian, T Lai, F Omidi - arXiv preprint arXiv:2404.16354, 2024 - arxiv.org
In this study, we examine the modular transformations of the (root-) $\text {T}\overline {\text
{T}} $ deformed torus partition function of a two-dimensional CFT (with a gravitational …
