One-loop analysis with nonlocal boundary conditions
Giampiero Esposito, Elisabetta Di Grezia
In the eighties, Schroder studied a quantum mechanical model where the stationary states of Schrodinger's equation obey nonlocal boundary conditions on a circle in the plane. For s…
The Seiberg-Witten map for non-commutative pure gravity and vacuum Maxwell theory
Elisabetta Di Grezia, Giampiero Esposito, Marco Figliolia +1
In this paper the Seiberg-Witten map is first analyzed for non-commutative Yang-Mills theories with the related methods, developed in the literature, for its explicit construction,…
The scalar wave equation in a non-commutative spherically symmetric space-time
Elisabetta Di Grezia, Giampiero Esposito, Gennaro Miele
Recent work in the literature has studied a version of non-commutative Schwarzschild black holes where the effects of non-commutativity are described by a mass function depending o…
Gravitational amplitudes in black-hole evaporation: the effect of non-commutative geometry
Elisabetta Di Grezia, Giampiero Esposito, Gennaro Miele
Recent work in the literature has studied the quantum-mechanical decay of a Schwarzschild-like black hole, formed by gravitational collapse, into almost-flat space-time and weak ra…
Space-time symmetry restoration in cosmological models with Kalb--Ramond and scalar fields
E. Di Grezia, G. Mangano, G. Miele
We study symmetry of space-time in presence of a minimally coupled scalar field interacting with a Kalb--Ramond tensor fields in a homogeneous but initially anisotropic universe. T…
