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…

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…
