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…
Two interacting conformal Carroll particles
Roberto Casalbuoni, Daniele Dominici, Joaquim Gomis
In this note we analyse two different models of two interacting conformal Carroll particles that can be obtained as the Carrollian limit of two relativistic conformal particles. Th…
Electric/Magnetic Newton-Hooke and Carroll Jackiw-Teitelboim Gravity
Luis Avilés, Joaquim Gomis, Diego Hidalgo +1
We construct the electric and magnetic Newton-Hooke and Carroll Jackiw-Teitelboim gravity theories using the isomorphism of Newton-Hooke and (A-)dS Carroll algebras in $(1+1)…
Non-Lorentzian theories with and without constraints
Eric A. Bergshoeff, Joaquim Gomis, Axel Kleinschmidt
We exhibit a new method of constructing non-Lorentzian models by applying a method we refer to as starting from a so-called seed Lagrangian. This method typically produces addition…
Multisymplectic Constraint Analysis of Scalar Field Theories, Chern-Simons Gravity, and Bosonic String Theory
Joaquim Gomis, Arnoldo Guerra, Narciso Román-Roy
The (pre)multisymplectic geometry of the De Donder--Weyl formalism for field theories is further developed for a variety of field theories including a scalar field theory from the…
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…
