Spin structures and AdS4 holography

Spin holography II

The interference of the directly emitted photoelectron wave and the wave scattered coherently by neighboring atoms gives holographic fringes in the photoelectron emission intensity I(R̂). In the electron emission holography technique in surface physics, I(R̂) is inverted holographically to give a 3Dimage of the environment of the source atom. Earlier [1]– [2], we pointed out that the polarization...

Gauge Non-Invariant Higher-Spin Currents in AdS4

Conserved currents of any spin t > 0 built from bosonic symmetric massless gauge fields of arbitrary integer spins s1 + s2 > t in AdS4 are found. Analogous to the case of 4d Minkowski space, currents considered in this paper are not gauge invariant, but generate gauge-invariant conserved charges.

Torsion and the Gravity Dual of Parity Breaking in AdS4/CFT3 Holography

We study four dimensional gravity with a negative cosmological constant deformed by the Nieh-Yan torsional topological invariant with a spacetime-dependent coefficient. We find an exact solution of the Euclidean system, which we call the torsion vortex, having two asymptotic AdS4 regimes connected by a wormhole and supported by a pseudoscalar with a kink profile. We propose that the torsion vor...

Holography, Duality and Higher-Spin Theories

I review recent work on the holographic relation between higher-spin theories in Anti-de Sitter spaces and conformal field theories. I present the main results of studies concerning the higher-spin holographic dual of the three-dimensional O(N) vector model. I discuss the special role played by certain double-trace deformations in Conformal Field Theories that have higher-spin holographic duals...
