We study the concept of Carrollian spacetime starting from its underlying fiber-bundle structure. The latter admits an Ehresmann connection, which enables a natural separation of time and space, preserved by the subset of Carrollian diffeomorphisms. These allow for the definition of Carrollian tensors and the structure at hand provides the designated tools for describing the geometry of null hypersurfaces embedded in Lorentzian manifolds. Using these tools, we investigate the conformal isometries of general Carrollian spacetimes and their relationship with the BMS group.

  1. Null Strings Gauged and Reloaded, I: Null Strings Have Carroll-Weyl Gauge Symmetry

    hep-th 2026-05 unverdicted novelty 7.0

    Null strings admit two Carroll-Weyl gauge scalings; the standard ILST action arises by fixing one of them, with the residual symmetry matching an overlooked partial gauge symmetry identified in prior work.

  2. Kinetic Theory of Carroll Hydrodynamics

    hep-th 2026-05 unverdicted novelty 7.0

    A kinetic theory of interacting instantonic branes yields a first-principles derivation of Carrollian fluid equations and initial elements of Carrollian thermodynamics.

  3. Kinetic Theory of Carroll Hydrodynamics

    hep-th 2026-05 unverdicted novelty 7.0

    A microscopic derivation of Carrollian fluid equations from a statistical mechanics of interacting instantonic branes, plus initial elements of Carrollian thermodynamics.

  4. Carroll supergravities

    hep-th 2026-07 accept novelty 6.0

    Electric and magnetic Carrollian limits of N=1, D=4 supergravity are obtained by Hamiltonian contraction, yielding ultralocal electric and gradient-retaining magnetic theories with simplified constraint algebras.

  5. Large-$N$ Carrollian Thermodynamics from AdS Black-Hole Phase-Space Contractions

    hep-th 2026-06 unverdicted novelty 6.0

    Finite Carrollian black-hole thermodynamics arises as a double-scaled low-temperature large-N ensemble in AdS/CFT, with the boundary Brown-York stress tensor reproducing the contracted bulk Hamiltonian and first law.

  6. Large-$N$ Carrollian Thermodynamics from AdS Black-Hole Phase-Space Contractions

    hep-th 2026-06 unverdicted novelty 6.0

    Finite Carrollian limit of extended AdS first law is reinterpreted as double-scaled large-N low-temperature holographic ensemble with finite products, new boundary stress tensor, and celestial correlator representations.

  7. Hamiltonian formulation of Carrollian Maxwell theory in Deformed Light-cone Kaluza-Klein-like Null reduction

    hep-th 2026-06 unverdicted novelty 6.0

    Derives Carrollian Maxwell theories (magnetic and electric) plus new scalar couplings through deformed light-cone null reduction while keeping first-class Gauss constraint and gauge invariance.

  8. The gravitational S-matrix from the path integral: asymptotic symmetries and soft theorems

    hep-th 2026-03 unverdicted novelty 6.0

    A path integral with asymptotic boundary conditions produces the gravitational S-matrix and derives soft graviton theorems from extended BMS symmetry Ward identities.

  9. Radiation in Fluid/Gravity and the Flat Limit

    hep-th 2025-08 unverdicted novelty 6.0

    Establishes a holographic link between bulk gravitational radiation and dissipative corrections plus entropy production in boundary fluids, then constructs Carrollian analogues and celestial observables in the flat limit.

  10. Carrollian Perspective on Celestial Holography

    hep-th 2022-02 unverdicted novelty 6.0

    A 3d sourced conformal Carrollian field theory is proposed to holographically capture 4d flat gravity kinematics, with Ward identities matching 2d celestial CFT after relating operators.

    Lecture notes that build the BMS group from prerequisites to applications in soft theorems, memory effects, and new material on asymptotic conformal Killing horizons.

  12. A Century of Group Theory in Particle Physics and Beyond

    hep-th 2026-07 unverdicted novelty 1.0

    A historical and pedagogical survey of group theory's role in particle physics, statistical mechanics, and a quantum-group model of the genetic code.
