Non-standard quantum algebras and infinite-dimensional PT-symmetric systems
Ãngel Ballesteros, Romina RamÃrez, Marta Reboiro
In this work, we introduce a PT-symmetric infinite-dimensional representation of the Uz(sl(2,R)) Hopf algebra, and we analyse a multiparametric family of Hamiltonians constructed f…

Noncommutative Lightcones from Quantum SO(2,1) Conformal Groups
Martina Adamo, Angel Ballesteros, Flavio Mercati
Five new families of noncommutative lightcones in 2+1 dimensions are presented as the quantizations of the inequivalent Poisson homogeneous structures that emerge when the lightcon…
