Testing quantum-spacetime relativity with gamma-ray telescopes

  journal={arXiv: High Energy Astrophysical Phenomena},
Observations of gamma-ray bursts are being used to test for a momentum dependence of the speed of photons, partly motivated by preliminary results reported in analyses of some quantum-spacetime scenarios. The relationship between time of arrival, momentum of the photon and redshift of the source which is used for these purposes assumes a "breakdown" of relativistic symmetries, meaning that it is a preferred-frame scenario which does not satisfy the Relativity Principle. The alternative… Expand

Testing noncommutative spacetimes and violations of the Pauli Exclusion Principle through underground experiments
We propose to deploy limits that arise from different tests of the Pauli Exclusion Principle in order: i) to provide theories of quantum gravity with an experimental guidance; ii) to distinguishExpand
Klein–Gordon field from the XXZ Heisenberg model
We examine the recently introduced idea of Spin-Field Correspondence (SFC) focusing on the example of the spin system described by the XXZ Heisenberg model with external magnetic field. TheExpand
A modern guide to {\rm $\theta$}-Poincar\'e
Motivated by the recent interest in underground experiments phenomenology, we review the main aspects of one specific non-commutative space-time model, based on the Groenewold-Moyal plane algebra,Expand
Quantum gravity: A brief history of ideas and some prospects
We present a bird’s-eye survey on the development of fundamental ideas of quantum gravity, placing emphasis on perturbative approaches, string theory, loop quantum gravity, and black holeExpand
