Massive and massless particles in Mielke--Baekler geometries
Carles Batlle, Roberto Casalbuoni, Daniele Dominici +3
The paper builds worldline actions for massive and massless spinning particles moving in three‑dimensional Mielke‑Baekler spacetimes, exploring both torsional (teleparallel) and Le…

A general action for a particle in 2+1 anti-de Sitter space
Carles Batlle, Joaquim Gomis
We discuss a general action for a particle in AdS using the non-linear realization framework. Critical sectors are found and characterized in terms of the parameters appearing…

A Celestial Kinematical Interpretation for an Extended BMS
Carles Batlle, Roberto Casalbuoni, Daniele Dominici +2
Motivated by the work of Longhi and Materassi, who constructed a realisation of the (centreless) BMS algebra for the massive Klein-Gordon field in , we build a realisation…
