Non-Relativistic BMS algebra
Carles Batlle, Diego Delmastro, Joaquim Gomis
We construct two possible candidates for the non-relativistic algebra in 4 space-time dimensions by contracting the original relativistic alge…

Canonical Realization of (2+1)-dimensional Bondi-Metzner-Sachs symmetry
Carles Batlle, Victor Campello, Joaquim Gomis
We construct canonical realizations of the algebra as symmetry algebras of a free Klein-Gordon (KG) field in dimensions, for both the massive and massless…

Tachyons in the Galilean limit
Carles Batlle, Joaquim Gomis, Luca Mezincescu +1
The Souriau massless Galilean particle of "colour" and spin is shown to be the Galilean limit of the Souriau tachyon of mass and spin . We compare and contrast…
