Anti-de Sitter, plane waves and quantum field theory
We present a new plane-wave expansion of the Wightman functions of anti de Sitter scalar fields and showcase its conceptual and technical importance in AdS quantum field theory. We deduce from it a…

Extracting Edge Modes: Reduction of 3D and 2D Gravities
We investigate the boundary reduction of 3D Einstein gravity and JT gravity into their respective edge mode theories - namely, the Liouville and Alekseev-Shatashvili, and Schwarzian models. By…

Soft unification of exceptional effective field theories in de Sitter space
We uncover a surprising universal soft behaviour (USB) of a de Sitter (dS) S-matrix for all exceptional effective field theories (EFTs) in dS space, stemming from the recently proposed…

Superconformal symmetry in a class of Schellekens theories
In 2023, Moore and Singh used the theory of orbifold vertex operator algebras to explicitly construct an N = 1 supercurrent in the Beauty and the Beast module of Dixon, Ginsparg, and…

Resolving BCFT bulk-cone singularities in braneworlds and top-down holography
Two-point functions in BCFTs exhibit characteristic singularities compared to standard CFTs due to reflected light cones. In holographic BCFTs, further singularities, which need not be related to…

Massive Spinning Fields During Inflation: Feynman rules and correlator comparison
We consider the dynamics of massive spinning fields during inflation and the resulting signatures in the cosmological correlators of inflaton perturbations computed in the Poincaré patch of de Sitter…

Supersymmetric lattice theories on curved space
We show how to construct Hamiltonian lattice theories with one exact supersymmetry on arbitrary triangulations of curved space in any number of dimensions. Both bosons and fermions satisfy discrete…

Boundary Actions and Loop Groups: A Geometric Picture of Gauge Symmetries at Null Infinity
In previous work arXiv:2407.13556, we proposed an extended phase space structure at null infinity accommodating large gauge symmetries for subn-leading soft theorems in Yang-Mills, via dressing…

The gyromagnetic factor of charged rotating black holes in various dimensions from scattering amplitudes
Classical black hole spacetimes can be recovered from the classical limit of quantum scattering amplitudes in a low-energy effective field theory of gravity. In this work we compute, at first…

Gravitational constant as a conserved charge in black hole thermodynamics
Recent work has shown that couplings multiplying individual terms in a Lagrangian can be promoted to conserved charges by introducing scalar-gauge pairs. The gravitational constant, however, plays a…

A Brief Note on Complex AdS-Schwarzschild Black Holes
In the context of thermodynamics of asymptotically anti-de Sitter spaces, it is often stated that at very low temperatures, there is only one saddle point available-namely, thermal AdS-and hence this…

A Hilbert Series for Generalized Toric Polygons
We study the Hilbert series for 5d Superconformal Field Theories (SCFTs) engineered by Generalized Toric Polygons (GTPs), which extend the geometric realization of these theories from toric…

Saturation of Pauli blocking in near-extremal charged Nariai black holes

Testing the Heterotic String with the Axion-Photon Coupling

Symmetry TFTs for Continuous Spacetime Symmetries
We propose a Symmetry Topological Field Theory (SymTFT) for continuous spacetime symmetries. For a d-dimensional theory, it is given by a (d+1)-dimensional BF-theory for the spacetime symmetry…

Vanishing of the H3 obstruction for time-reversal symmetry in (2+1)D abelian bosonic TQFTs

Higgs Field as Architect of a Geodesically Complete Universe and Agent for New Physics in Interiors of Black Holes

Similarities in the evaporation of saturated solitons and black holes
It has been suggested some time ago that many black hole properties are not specific to gravity, but rather are shared by a large class of objects, the so-called saturons, that saturate the quantum…
