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 …

Hunting Quantum Gravity with Analogs: the case of graphene

G Acquaviva, A Iorio, P Pais, L Smaldone - Universe, 2022 - mdpi.com
Analogs of fundamental physical phenomena can be used in two ways. One way consists in
reproducing specific aspects of the classical or quantum gravity of quantum fields in curved …

Quantum field theory in curved graphene spacetimes, Lobachevsky geometry, Weyl symmetry, Hawking effect, and all that

A Iorio, G Lambiase - Physical Review D, 2014 - APS
The solutions of many issues, of the ongoing efforts to make deformed graphene a tabletop
quantum field theory in curved spacetimes, are presented. A detailed explanation of the …

Dirac equation for cold atoms in artificial curved spacetimes

O Boada, A Celi, JI Latorre… - New Journal of …, 2011 - iopscience.iop.org
We argue that the Fermi–Hubbard Hamiltonian describing the physics of ultracold atoms on
optical lattices in the presence of artificial non-Abelian gauge fields is exactly equivalent to …

Generalized uncertainty principle in three-dimensional gravity and the BTZ black hole

A Iorio, G Lambiase, P Pais, F Scardigli - Physical Review D, 2020 - APS
We investigate the structure of the gravity-induced generalized uncertainty principle in three
dimensions. The subtleties of lower-dimensional gravity, and its important differences …

The Hawking–Unruh phenomenon on graphene

A Iorio, G Lambiase - Physics Letters B, 2012 - Elsevier
We find that, for a very specific shape of a monolayer graphene sample, a general relativistic-
like description of a back-ground spacetime for grapheneʼs conductivity electrons is very …

Constructing superconductors by graphene Chern–Simons wormholes

S Capozziello, R Pincak, EN Saridakis - Annals of Physics, 2018 - Elsevier
We propose a new model which simulates the motion of free electrons in graphene by the
evolution of strings on manifolds. In this model, molecules which constitute sheets of …

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 …

Generalized Dirac structure beyond the linear regime in graphene

A Iorio, P Pais, IA Elmashad, AF Ali… - … Journal of Modern …, 2018 - World Scientific
We show that a generalized Dirac structure survives beyond the linear regime of the low-
energy dispersion relations of graphene. A generalized uncertainty principle of the kind …

Curved spacetimes and curved graphene: A status report of the Weyl symmetry approach

A Iorio - International Journal of Modern Physics D, 2015 - World Scientific
This is a status report about the ongoing work on the realization of quantum field theory on
curved graphene spacetimes that uses Weyl symmetry. The programme is actively pursued …
