Torsion at different scales: from materials to the Universe

NE Mavromatos, P Pais, A Iorio - Universe, 2023 - mdpi.com
The concept of torsion in geometry, although known for a long time, has not gained
considerable attention from the physics community until relatively recently, due to its diverse …

Three “layers” of graphene monolayer and their analog generalized uncertainty principles

A Iorio, B Ivetić, S Mignemi, P Pais - Physical Review D, 2022 - APS
We show that graphene, in its simplest form and settings, is a practical tabletop realization of
the analog of exotic quantum gravity scenarios, which are speculated to lead to certain …

Hunting Quantum Gravity with Analogs: The Case of High-Energy Particle Physics

P Castorina, A Iorio, H Satz - Universe, 2022 - mdpi.com
In this review, we collect, for the first time, old and new research results, and present future
perspectives on how hadron production, in high-energy scattering processes, can …

Generalized Ellis-Bronnikov bilayer graphene wormholelike surface

TF de Souza, ACA Ramos, RN Costa Filho, J Furtado - Physical Review B, 2022 - APS
In this paper, we investigate the spinless stationary Schrödinger equation for the electron
when it is permanently bound to a generalized Ellis-Bronnikov bilayer graphene …

Massive Dirac equation in static Bumblebee black hole space-times, detailed derivations and novel exact solutions

D Senjaya - Journal of High Energy Astrophysics, 2024 - Elsevier
In this work, we construct and investigate the relativistic spin-1 2 fermionic fields quantum
dynamics in static spherically symmetric Bumblebee black hole background. The derivation …

The propagating modes of the massless Rarita--Schwinger system

M Valenzuela, J Zanelli - arXiv preprint arXiv:2305.00106, 2023 - arxiv.org
The counting of the degrees of freedom of the massless Rarita-Schwinger theory is revisited
using covariant and non-covariant techniques. The Ogievetsky-Sokatchev spin-block …

Massless Rarita-Schwinger equations: Half and three halves spin solution

M Valenzuela, J Zanelli - SciPost Physics, 2024 - scipost.org
Counting the degrees of freedom of the massless Rarita-Schwinger theory is revisited using
Behrends-Fronsdal projectors. The identification of the gauge invariant part of the vector …

Quantum black holes as classical space factories

A Iorio, L Smaldone - International Journal of Modern Physics D, 2023 - World Scientific
Space and matter may both be manifestations of a single fundamental quantum dynamics,
as it may become evident during black-hole evaporation. Inspired by the fact that quantum …

Classical space from quantum condensates

A Iorio, L Smaldone - Journal of Physics: Conference Series, 2023 - iopscience.iop.org
We review the boson transformation method to deal with spontaneous symmetry breaking in
quantum field theory, focussing on how it describes the emergence of extended and …

Time-loops to spot torsion on bidimensional Dirac materials with dislocations

A Iorio, P Pais - Journal of Physics: Conference Series, 2023 - iopscience.iop.org
Assuming that, with some care, dislocations could be meaningfully described by torsion, we
propose here a scenario based on an previously unexplored role of time in the low-energy …
