A canonical realization of the Weyl BMS symmetry
Carles Batlle, Víctor Campello, Joaquim Gomis
We construct a free field realization of an extension of the BMS algebra in dimensional space-time. Besides the supertranslations and superrotations, the extension contains a…

Space-time Schrödinger symmetries of a post-Galilean particle
Carles Batlle, Joaquim Gomis
We study the space-time symmetries of the actions obtained by expanding the action for a massive free relativistic particle around the Galilean action. We obtain all the point spac…

Lie Symmetries of Non-Relativistic and Relativistic Motions
Carles Batlle, Joaquim Gomis, Sourya Ray +1
We study the Lie symmetries of non-relativistic and relativistic higher order constant motions, in spatial dimensions, like constant acceleration, constant rate-of-change -of-a…
