Quantum Carroll/fracton particles
José Figueroa-O'Farrill, Alfredo Pérez, Stefan Prohazka
We classify and relate unitary irreducible representations (UIRs) of the Carroll and dipole groups, i.e., we define elementary quantum Carroll and fracton particles and establish a…
Magnetic Carrollian gravity from the Carroll algebra
Andrea Campoleoni, Marc Henneaux, Simon Pekar +2
We explicitly establish the equivalence between the magnetic Carrollian limit of Einstein gravity defined through the Hamiltonian formalism and the Carrollian theory of gravity def…
Higher Spin Black Holes with Soft Hair
Daniel Grumiller, Alfredo Perez, Stefan Prohazka +2
We construct a new set of boundary conditions for higher spin gravity, inspired by a recent "soft Heisenberg hair"-proposal for General Relativity on three-dimensional Anti-de Sitt…
Superselection rule for the cosmological constant in three-dimensional spacetime
Claudio Bunster, Alfredo Perez
Efforts to understand the origin of the cosmological constant Λ and its observed value have led to consider it as a dynamical field rather than as a universal constant. Then the po…
Higher spin extension of cosmological spacetimes in 3D: asymptotically flat behaviour with chemical potentials and thermodynamics
Javier Matulich, Alfredo Perez, David Tempo +1
A generalized set of asymptotic conditions for higher spin gravity without cosmological constant in three spacetime dimensions is constructed. They include the most general tempora…
Generalized Black Holes in Three-dimensional Spacetime
Claudio Bunster, Marc Henneaux, Alfredo Perez +2
Three-dimensional spacetime with a negative cosmological constant has proven to be a remarkably fertile ground for the study of gravity and higher spin fields. The theory is topolo…
