First results of the Noether theorem for Hopf-algebra spacetime symmetries
Giovanni Amelino-Camelia, Giulia Gubitosi, Antonino Marciano +4
We summarize here the first results obtained using a technique we recently developed for the Noether analysis of Hopf-algebra spacetime symmetries, including the derivation of cons…
Twisted Hopf symmetries of canonical noncommutative spacetimes and the no-pure-boost principle
Giovanni Amelino-Camelia, Fabio Briscese, Giulia Gubitosi +3
We study the twisted-Hopf-algebra symmetries of observer-independent canonical spacetime noncommutativity, for which the commutators of the spacetime coordinates take the form [x^{…
Fock space, quantum fields and kappa-Poincaré symmetries
Michele Arzano, Antonino Marciano
We study the quantization of a linear scalar field, whose symmetries are described by the kappa-Poincare' Hopf-algebra, via deformed Fock space construction. The one-particle secto…
Cosmological Casimir effect with maximum planckian momentum and accelerating universe
F. Briscese, A. Marciano
We develop here a mechanism that, without making use of a cosmological constant, reproduces an accelerating universe. This is done by taking into account Casimir vacuum energy dens…
Symplectic geometry and Noether charges for Hopf algebra space-time symmetries
Michele Arzano, Antonino Marciano
There has been a certain interest in some recent works in the derivation of Noether charges for Hopf-algebra space-time symmetries. Such analyses relied rather heavily on delicate…
