Tutorial on scale and conformal symmetries in diverse dimensions [PDF]
J.Phys.A44:223001,2011, 2011 We review the relation between scale and conformal symmetries in various models and dimensions. We present a dimensional reduction from relativistic to non-relativistic conformal dynamics.

Analytic bootstrap for the localized magnetic field
Journal of High Energy Physics, 2023 We study the two-point function of local operators in the critical O(N) model in the presence of a magnetic field localized on a line. We use a recently developed conformal dispersion relation to compute the correlator at first order in the ϵ-expansion ...

Yukawa interactions at large charge
Journal of High Energy Physics, 2022 We extend the fixed-charge semiclassical method by computing anomalous dimensions of fixed-charge scalar operators in models with Yukawa interactions. In particular, we discuss the Nambu-Jona-Lasinio-Yukawa theory as well as an asymptotically safe gauge ...

Narain CFTs and quantum codes at higher genus
Journal of High Energy Physics, 2023 Code CFTs are 2d conformal field theories defined by error-correcting codes. Recently, Dymarsky and Shapere generalized the construction of code CFTs to include quantum error-correcting codes. In this paper, we explore this connection at higher genus. We

Analytic bootstrap of mixed correlators in the O(n) CFT
Journal of High Energy Physics, 2022 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 dimensions.

A CFT interpretation of cosmological correlation functions in α−vacua in de-Sitter space
Journal of High Energy Physics, 2023 De-Sitter(dS) space allows for a generalized class of vacua, known as α–vacua, described by some parameters. The Bunch-Davies (BD) vacuum is a point in this parameter space. The cosmological correlation function in BD vacuum in four dimensions and can be

Modular differential equations with movable poles and admissible RCFT characters
Journal of High Energy Physics, 2023 Studies of modular linear differential equations (MLDE) for the classification of rational CFT characters have been limited to the case where the coefficient functions (in monic form) have no poles, or poles at special points of moduli space.

Tensors and spinors in de Sitter space
Journal of High Energy Physics, 2022 We construct the Wightman function for symmetric traceless tensors and Dirac fermions in dS d+1 in a coordinate and index free formalism using a d + 2 dimensional ambient space. We expand the embedding space formalism to cover spinor and tensor fields in

An integer basis for celestial amplitudes
Journal of High Energy Physics, 2023 We present a discrete basis of solutions of the massless Klein-Gordon equation in 3 + 1 Minkowski space which transform as 𝔰𝔩(2, ℂ) Lorentz/conformal primaries and descendants, and whose elements all have integer conformal dimension.

Restricted Weyl Symmetry and Spontaneous Symmetry Breakdown of Conformal Symmetry [PDF]
, 2021 We elucidate the relation between the restricted Weyl symmetry and spontaneous symmetry breakdown of conformal symmetry. Using a scalar-tensor gravity, we show that the restricted Weyl symmetry leads to spontaneous symmetry breakdown of a global scale symmetry when the vacuum expectation value of a scalar field takes a non-zero value.
