The Weyl-Mellin quantization map for -Minkowski Noncommutative Spacetime
Alessandro Carotenuto, Fedele Lizzi, Mattia Manfredonia +1
We present a quantization of the functions of spacetime, i.e.\ a map, analog to Weyl map, which reproduces the -Minkowski commutation relations, and it has the desirable propert…
The Momentum Spaces of -Minkowski noncommutative spacetime
Fedele Lizzi, Flavio Mercati, Mattia Manfredonia
A useful concept in the development of physical models on the -Minkowski noncommutative spacetime is that of a curved momentum space. This structure is not unique: several inequ…
Localizability in -Minkowski Spacetime
Fedele Lizzi, Mattia Manfredonia, Flavio Mercati
Using the methods of ordinary quantum mechanics we study -Minkowski space as a quantum space described by noncommuting self-adjoint operators, following and enlarging arXiv:1811…
Localization and Reference Frames in -Minkowski Spacetime
Fedele Lizzi, Mattia Manfredonia, Flavio Mercati +1
We study the limits to the localizability of events and reference frames in the -Minkowski quantum spacetime. Our main tool will be a representation of the -Minkowski commuta…
Spin, torsion and violation of null energy condition in traversable wormholes
Emmanuele Battista, Elisabetta Di Grezia, Mattia Manfredonia +1
The static spherically symmetric traversable wormholes are analysed in the Einstein- Cartan theory of gravitation. In particular, we computed the torsion tensor for matter fields w…
Characterising exotic matter driving wormhole
Marco Chianese, Elisabetta Di Grezia, Mattia Manfredonia +1
In this paper, we develop an iterative approach to span the whole set of exotic matter models able to drive a traversable wormhole. The method, based on a Taylor expansion of metri…
