abstract

The symmetry algebra of asymptotically flat spacetimes at null infinity in three dimensions is the semi-direct sum of the infinitesimal diffeomorphisms on the circle with an abelian ideal of supertranslations. The associated charge algebra is shown to admit a non trivial classical central extension of Virasoro type closely related to that of the anti-de Sitter case.

Timelike Liouville theory and AdS$_3$ gravity at finite cutoff

hep-th · 2025-08-05 · unverdicted · novelty 6.0

Proposes that AdS3 gravity at finite cutoff is dual to a CFT2 coupled to timelike Liouville theory deformed by a marginal operator, with checks via semiclassical partition functions and EOM matching.

QFT in Klein space

hep-th · 2025-05-22 · unverdicted · novelty 6.0

Authors construct canonical and path-integral quantizations for QFT in Klein space using extra modes, deriving correlation functions that match Minkowski space via analytical continuation.

Carroll fermions, expansions and the lightcone

hep-th · 2026-04-15 · unverdicted · novelty 6.0

Carrollian fermion actions are obtained from relativistic Dirac theory via c-expansion and connected to light-cone dynamics through co-dimension one Carroll subalgebras in the Poincaré algebra.

The Carrollian Kaleidoscope

hep-th · 2025-06-19 · unverdicted · novelty 1.0

A review summarizing Carrollian symmetries, CCFT constructions, and applications in AFS holography, Carroll hydrodynamics, and condensed matter phenomena such as fractons and flat bands.
