Towards holographic higher-spin interactions: Four-point functions and higher-spin exchange
Xavier Bekaert, Johanna Erdmenger, Dmitry Ponomarev +1
Within holography, we calculate the contribution of an arbitrary spin-s gauge boson exchange in to the four-point function with scalar operators on the boundary. As an…
Connections and dynamical trajectories in generalised Newton-Cartan gravity I. An intrinsic view
Xavier Bekaert, Kevin Morand
The "metric" structure of nonrelativistic spacetimes consists of a one-form (the absolute clock) whose kernel is endowed with a positive-definite metric. Contrarily to the relativi…
Thermodynamics of Asymptotically Conical Geometries
Mirjam Cvetic, Gary W. Gibbons, Zain H. Saleem
We study the thermodynamical properties of a class of asymptotically conical (AC) geometries known as "subtracted geometries". We derive the mass and angular momentum from the regu…
Entropy discrepancy and total derivatives in trace anomaly
Amin Faraji Astaneh, Alexander Patrushev, Sergey N. Solodukhin
In this note we address the discrepancy found by Hung, Myers and Smolkin between the holographic calculation of entanglement entropy (using the Jacobson-Myers functional for the ho…
Wigner-Souriau translations and Lorentz symmetry of chiral fermions
C. Duval, M. Elbistan, P. A. Horvathy +1
Chiral fermions can be embedded into Souriau's massless spinning particle model by "enslaving" the spin, viewed as a gauge constraint. The latter is not invariant under Lorentz boo…
Flato-Fronsdal theorem for higher-order singletons
Thomas Basile, Xavier Bekaert, Nicolas Boulanger
We prove a generalised Flato-Fronsdal theorem for higher-order, scalar and spinor, singletons. In the resulting infinite tower of bulk higher-spin fields, we point out the occurren…
