I review the current status of phenomenological programs inspired by quantum-spacetime
research. I stress in particular the significance of results establishing that certain data …

This is an introductory review about the ongoing search for a signal of Lorentz Invariance
Violation (LIV) in cosmic rays. We first summarise basic aspects of cosmic rays, focusing on …

We argue that the notion of identical particles is no longer well defined in quantum systems
governed by noncommutative deformations of spacetime symmetries. Such models are …

Within the setting of a recently proposed model of quantum fields on noncommutative
Minkowski space, the consequences of the consistent application of the proper, untwisted …

Quantum field theories on noncommutative Minkowski space are studied in a model-
independent setting by treating the noncommutativity as a deformation of quantum field …

In the present work we review the twisted field construction of quantum field theory on
noncommutative spacetimes based on twisted Poincaré invariance. We present the latest …

We give an introductory review of quantum physics on the noncommutative space–time
called the Groenewold–Moyal plane. Basic ideas like star products, twisted statistics, second …

It is by now well known that the Poincaré group acts on the Moyal plane with a twisted
coproduct. Poincaré invariant classical field theories can be formulated for this twisted …

Noncommutative quantum field theories and their global quantum group symmetries provide
an intriguing attempt to go beyond the realm of standard local quantum field theory. A …

Recent work indicates an approach to the formulation of diffeomorphism invariant quantum
field theories (qft's) on the Groenewold-Moyal plane. In this approach to the qft's, statistics …
