Prism Effect in Quantum Gravity
Aliasghar Parvizi, Tomasz PawÅowski
The paper develops a general framework using an extended Born-Oppenheimer approximation to describe how electromagnetic waves propagate in a quantum‑gravity-modified spacetime, pre…
Revisiting light propagation over (loop) quantum Universe
Aliasghar Parvizi, Tomasz PawÅowski
We investigate the propagation of electromagnetic waves over a quantum cosmological background, aiming to uncover potential signatures of quantum gravity through modifications to t…
Fracton and Non-Lorentzian Particle Duality: Gauge Field Couplings and Geometric Implications
M. M. Ahmadi-Jahmani, A. Parvizi
Fractons, characterized by restricted mobility and governed by higher-moment conservation laws, represent a novel phase of matter with deep connections to tensor gauge theories and…
Freelance Holography, Part II: Moving Boundary in Gauge/Gravity Correspondence
A. Parvizi, M. M. Sheikh-Jabbari, V. Taghiloo
We continue developing the freelance holography program, formulating gauge/gravity correspondence where the gravity side is formulated on a space bounded by a generic timelike codi…
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…
