Shadows in conformally related gravity theories

open access: yesPhysics Letters B, 2022
Null geodesics are invariant under a conformal transformation, and thus it might seem natural to assume that the observables corresponding to the shadow of a space-time are also conformally invariant. Here, we argue instead, that since the Arnowitt-Deser-

A CFT distance conjecture

open access: yesJournal of High Energy Physics, 2021
We formulate a series of conjectures relating the geometry of conformal manifolds to the spectrum of local operators in conformal field theories in d > 2 spacetime dimensions. We focus on conformal manifolds with limiting points at infinite distance with

Generalized compact star models with conformal symmetry

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We generate a new generalized regular charged anisotropic exact model that admits conformal symmetry in static spherically symmetric spacetime. Our model was examined for physical acceptability as realistic stellar models. The regularity is not violated,

Stringy tachyonic instabilities of non-supersymmetric Ricci flat backgrounds

open access: yesJournal of High Energy Physics, 2021
Superstring/M-theory compactified on compact Ricci flat manifolds have recently been conjectured to exhibit instabilities whenever the metrics do not have special holonomy.

A scattering amplitude for massive particles in AdS

open access: yesJournal of High Energy Physics, 2022
In this paper, we propose a conformally covariant momentum space representation of CFT correlation functions. We call it the AdS S-matrix. This representation has the property that it reduces to the S-matrix in the flat space limit.

Weyl Conformal Symmetry Model of the Dark Galactic Halo

open access: yesGalaxies, 2022
The postulate of universal conformal (local Weyl scaling) symmetry modifies both general relativity and the Higgs scalar field model. The conformal Higgs model (CHM) generates an effective cosmological constant that fits the observed accelerating Hubble ...

Ground state energy in a wormhole space-time [PDF]

open access: yes, 2002
The ground state energy of the massive scalar field with non-conformal coupling $\xi$ on the short-throat flat-space wormhole background is calculated by using zeta renormalization approach.

Partition functions of higher derivative conformal fields on conformally related spaces

open access: yesJournal of High Energy Physics, 2021
The character integral representation of one loop partition functions is useful to establish the relation between partition functions of conformal fields on Weyl equivalent spaces.

Root uniqueness of the Gakhov equation in the classes of functions with the bounded pre-Schwarzian

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
It was established that if the left-hand side of the Gakhov equation is bounded by the constant 2, then this equation has exactly one root in the unit disk, where the constant is sharp and the root is not necessarily zero. We revealed two aspects arising

Conformal Symmetry of Relativistic and Nonrelativistic Systems and AdS/CFT Correspondence [PDF]

open access: yes, 2003
The nonlinear realization of conformal so(2,d) symmetry for relativistic systems and the dynamical conformal so(2,1) symmetry of nonrelativistic systems are investigated in the context of AdS/CFT correspondence.
