Physical models from noncommutative causality
Nicolas Franco
We introduced few years ago a new notion of causality for noncommutative spacetimes directly related to the Dirac operator and the concept of Lorentzian spectral triple. In this pa…
Neutrino mixing, interval matrices and singular values
K. Bielas, W. Flieger, J. Gluza +1
We study the properties of singular values of mixing matrices embedded within an experimentally determined interval matrix. We argue that any physically admissible mixing matrix ne…
Inter-universal entanglement in a cyclic multiverse
Salvador Robles-Perez, Adam Balcerzak, Mariusz P. Dabrowski +1
We study scenarios of parallel cyclic multiverses which allow for a different evolution of the physical constants, while having the same geometry. These universes are classically d…
Braided Hopf algebras from twisting
Arkadiusz Bochniak, Andrzej Sitarz
We show that a class of braided Hopf algebras, which includes the braided is obtained by twisting. We show further examples and demonstrate that twisting of bicovariant d…
Energy Scale of Lorentz Violation in Rainbow Gravity
Nils A. Nilsson, Mariusz P. Dabrowski
We modify the standard relativistic dispersion relation in a way which breaks Lorentz symmetry - the effect is predicted in a high-energy regime of some modern theories of quantum…
