Hilbert space in the flat limit of AdS/CFT. I. Massive particles
Kevin Nguyen
The flat limit of AdS spacetime corresponds, at the level of the symmetry algebra, to the Inönü--Wigner contraction . We describe th…
Lectures on Carrollian Holography
Kevin Nguyen
Carrollian Holography aims to provide a holographic description of quantum gravity in asymptotically flat spacetimes, in terms of a novel kind of `carrollian' conformal field theor…
Hydrodynamics of two-dimensional CFTs
Kevin Nguyen
We demonstrate that the geometric action on a coadjoint orbit of the Virasoro group appropriately describes non-dissipative two-dimensional conformal fluids. While this action had…
Soft theorems and spontaneous symmetry breaking
Shreyansh Agrawal, Kevin Nguyen
The soft photon and soft graviton theorems of Weinberg are known to derive from conservation laws associated with asymptotic symmetries. Within the corresponding classical theories…
Operator Product Expansion in Carrollian CFT
Kevin Nguyen, Jakob Salzer
Carrollian conformal field theory offers an alternative description of massless scattering amplitudes, that is holographic in nature. In an effort to build a framework that is both…
Celestial decomposition of Wigner's particles
Lorenzo Iacobacci, Kevin Nguyen
We provide a detailed decomposition of Wigner's particles, defined as unitary irreducible representations of the Poincaré group, in terms of unitary representations of its Lorentz…
Massive carrollian fields at timelike infinity
Emil Have, Kevin Nguyen, Stefan Prohazka +1
Motivated by flat space holography, we demonstrate that massive spin- fields in Minkowski space near timelike infinity are massive carrollian fields on the carrollian counterpar…
Carrollian conformal correlators and massless scattering amplitudes
Kevin Nguyen
The theory of particle scattering is concerned with transition amplitudes between states that belong to unitary representations of the Poincaré group. The latter acts as the isomet…
