Higher-Spin Poisson Sigma Models and Holographic Duality for SYK Models
Xavier Bekaert, Alexey Sharapov, Evgeny Skvortsov
SYK models provide an interesting playground for exploring the correspondence. We focus on a class of SYK models that exhibit higher-spin symmetry, whose gravity sect…
Electromagnetic Interactions of Massive Higher-Spin Fields in 3D via Chiral Theory
Alexey Sharapov, David Shcherbatov, Evgeny Skvortsov
We address the issue of electromagnetic interaction for massive higher-spin fields in Minkowski space. We show that consistent field equations can be obtained through the dime…
Matter-coupled higher spin gravities in 3d: no- and yes-go results
Alexey Sharapov, Evgeny Skvortsov, Arseny Sukhanov
Massless higher-spin fields show no preference for any value of the cosmological constant in . All matter-free higher-spin gravities in 3d are equivalent to Chern-Simons theori…
Strong Homotopy Algebras for Chiral Higher Spin Gravity via Stokes Theorem
Alexey Sharapov, Evgeny Skvortsov, Richard Van Dongen
Chiral higher spin gravity is defined in terms of a strong homotopy algebra of pre-Calabi-Yau type (noncommutative Poisson structure). All structure maps are given by the integrals…
Classical Mechanics in Noncommutative Spaces: Confinement and More
Vladislav Kupriyanov, Maxim Kurkov, Alexey Sharapov
We consider a semi-classical approximation to the dynamics of a point particle in a noncommutative space. In this approximation, the noncommutativity of space coordinates is descri…
