Prism Effect in Quantum Gravity
Aliasghar Parvizi, Tomasz Pawłowski
Modifications to the dispersion relation of electromagnetic (EM) waves are a central probe in the search for quantum gravitational effects. In this work, we construct a general fra…
Revisiting light propagation over (loop) quantum Universe
Aliasghar Parvizi, Tomasz Pawłowski
We investigate the propagation of electromagnetic waves over a quantum cosmological background, aiming to uncover potential signatures of quantum gravity through modifications to t…
Photon rings in the metamaterial analog of a gravitomagnetic monopole
A. Parvizi, H. Forghani-Ramandy, E. Rahmani +1
After studying null geodesics in the equatorial plane in NUT spacetime, we show that there are unstable photon rings in this plane. Next we transform the metric of this plane to th…
White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era
R. Alves Batista, G. Amelino-Camelia, D. Boncioli +101
The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put…
