Torsional Carroll Gravity
P. Concha, N. Merino, L. Ravera +1
The ultra-relativistic (Carrollian) regime of gravity has recently emerged as a fertile framework for exploring holography, non-Lorentzian symmetries, and geometric limit of Genera…
Central Singularity of Three-Dimensional Kerr-de Sitter Black Holes
Mauro Carlone, Wolfgang Mück
For three-dimensional Kerr-de Sitter space-time, we find the singular energy-momentum and spin tensor sources that generate the non-trivial geometry. The energy-momentum tensor is…
Near-Horizon Symmetries in Einstein-Maxwell theory
Gianfranco De Simone
This manuscript aims to provide a comprehensive derivation of the Einstein-Maxwell charges and fluxes in the near-horizon region of a four-dimensional non-extremal black hole, with…
Covariant field theory of 3D massive fractons
Erica Bertolini, Matteo Carrega, Nicola Maggiore +1
We construct a covariant and gauge-invariant theory describing massive fractons in three spacetime dimensions, based on a symmetric rank-2 tensor field. The model includes a Chern-…
Thermodynamics of magnetized BPS baryonic layers and the effects of the Isospin chemical potential
Sergio Luigi Cacciatori, Fabrizio Canfora, Evangelo Delgado +2
Through the Hamilton-Jacobi equation of classical mechanics, BPS magnetized Baryonic layers (possessing both baryonic charge and magnetic flux) have been constructed in the gauged…
Amplitude prescriptions in field theories with complex poles
Damiano Anselmi, Fabio Briscese, Gianluca Calcagni +1
In the context of field theories with complex poles, we scrutinize four inequivalent ways of defining the scattering amplitudes, each forfeiting one or more tenets of standard quan…
