Dyonic black holes from dimensional reduction of five-dimensional Einstein-Gauss-Bonnet gravity
Z. Belkhadria, S. Mignemi, F. Paderi
We study the general black hole solutions of dimensionally reduced five-dimensional Einstein-Gauss-Bonnet gravity. The reduced theory contains gravity, electromagnetism and a scala…
CPT breaking in noncommutative Magueijo-Smolin model
S. Mignemi
We review an instance of noncommutative geometry based on a specific realization of the model of doubly special relativity proposed by Magueijo and Smolin (MS) on noncommutative sp…
New model of spontaneous scalarization of black holes induced by curvature and matter
Zakaria Belkhadria, Salvatore Mignemi
We propose a new model of black hole spontaneous scalarization that combines a scalar--Gauss--Bonnet interaction with a non--minimal coupling to a U(1) gauge field (a dark photon o…
Deriving the paradox: original derivation of Hawking radiation
Mariano Cadoni, Salvatore Mignemi, Mirko Pitzalis +1
We revisit Hawking's original derivation of the evaporation process in a non-stationary spacetime, presenting it in a clear and pedagogical manner, with a focus on the spherical co…
If the universe were curved and noncommutative
S. A. Franchino-Viñas, S. Mignemi
We review recent discussions concerning the definition of a quantum field theory in a curved and noncommutative space, the Snyder--de Sitter space. For a quartic self-interacting s…
Snyder-de Sitter meets the Grosse-Wulkenhaar model
S. A. Franchino-Viñas, S. Mignemi
We study an interacting scalar field defined on Snyder-de Sitter space. Due to the noncommutativity as well as the curvature of this space, the renormalization of…
