On emergent conformal symmetry near the photon ring

Journal of High Energy Physics, 2023
In this note we revisit the emergent conformal symmetry in the near-ring region of warped spacetime. In particular, we propose a novel construction of the emergent near-ring sl(2, ℝ)QNM symmetry.

A note on defect Mellin amplitudes

Journal of High Energy Physics, 2023
We generalize the Mellin representation for a generic co-dimension flat defect CFT. We study the analytic structure of the Mellin amplitudes. We also compute Witten diagrams for a generic co-dimension flat defect CFT.

Radiatively Induced Breaking of Conformal Symmetry in a Superpotential [PDF]

, 2016
Radiatively induced symmetry breaking is considered for a toy model with one scalar and one fermion field unified in a superfield. It is shown that the classical quartic self-interaction of the superfield possesses a quantum infrared singularity ...

Modularity and 4D-2D spectral equivalences for large-N gauge theories with adjoint matter [PDF]

, 2015
In recent work, we demonstrated that the confined-phase spectrum of non-supersymmetric pure Yang-Mills theory coincides with the spectrum of the chiral sector of a two-dimensional conformal field theory in the large-$N$ limit.

Conformal invariance in two-dimensional turbulence

, 2006
Simplicity of fundamental physical laws manifests itself in fundamental symmetries. While systems with an infinity of strongly interacting degrees of freedom (in particle physics and critical phenomena) are hard to describe, they often demonstrate ...

A non-commutative Minkowskian spacetime from a quantum AdS algebra [PDF]

, 2003
A quantum deformation of the conformal algebra of the Minkowskian spacetime in $(3+1)$ dimensions is identified with a deformation of the $(4+1)$-dimensional AdS algebra. Both Minkowskian and AdS first-order non-commutative spaces are explicitly obtained,

The geometry of gauged (super)conformal mechanics

Journal of High Energy Physics, 2022
Motivated by recently explored examples, we undertake a systematic study of conformal invariance in one-dimensional sigma models where an isometry group has been gauged.

Scalar tilt from broken conformal invariance

, 2010
Within recently proposed scenario which explains flatness of the spectrum of scalar cosmological perturbations by a combination of conformal and global symmetries, we discuss the effect of weak breaking of conformal invariance.

RG flows and stability in defect field theories

Journal of High Energy Physics, 2023
We investigate defects in scalar field theories in four and six dimensions in a double-scaling (semiclassical) limit, where bulk loops are suppressed and quantum effects come from the defect coupling. We compute β-functions up to four loops and find that

Fermions in boundary conformal field theory: crossing symmetry and E-expansion

Journal of High Energy Physics, 2023
We use the equations of motion in combination with crossing symmetry to constrain the properties of interacting fermionic boundary conformal field theories.
