This is a collection of my lecture notes on the higher-spin theory course given for students at
the Institute for Theoretical and Mathematical Physics, Lomonosov Moscow State University …

We study complex scalar theories with dipole symmetry and uncover a no-go theorem that
governs the structure of such theories and which, in particular, reveals that a Gaussian …

Higher Spin Gravity refers to extensions of gravity including at least one field of spin greater
than two. These extensions are expected to provide manageable models of quantum gravity …

We discuss three different (conformally) Carrollian geometries and their relation to null
infinity from the unifying perspective of Cartan geometry. Null infinity per se comes with …

In this paper, we study the Carrollian and Galilean conformal field theories (CCFT and
GCFT) in $ d> 2$ dimensions. We construct the highest weight representations (HWR) of …

We reduce the massless scalar field theory in Minkowski spacetime to future null infinity. We
compute the Poincaré flux operators, which can be generalized and identified as the …

A bstract Starting from the asymptotic kinematics of massless scalar fields near null infinity in
any spacetime dimension, we build two higher-spin extensions of the Carrollian definition of …

We show that, in any space-time dimension, the on-shell (electric) conformal Carrollian
scalar can be interpreted as the flat-space limit of the singleton representation of the …

A bstract Asymptotic symmetries in Carrollian gravitational theories in 3+ 1 space and time
dimensions obtained from “magnetic” and “electric” ultrarelativistic contractions of General …

In this work, we study the quantization of Carrollian conformal scalar theories, including two-
dimensional (2D) magnetic scalar and three-dimensional (3D) electric and magnetic scalars …
