Particle realization of Bondi-Metzner-Sachs symmetry in 2+1 space-time
Carles Batlle, Víctor Campello, Joaquim Gomis
We construct a Lorentz invariant massive particle model in (2+1) space-time with an enlarged set of symmetries which includes Bondi-Metzner-Sachs (BMS) translations (supertranslati…
Polyharmonic Green Functions and Nonlocal BMS Transformations of a Free Scalar Field
Carles Batlle, Victor Campello, Joaquim Gomis
We express the nonlocal BMS charges of a free massless Klein-Gordon scalar field in 2+1 in terms of the Green functions of the polyharmonic operators. Using the properties of these…
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…
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…
