Integrability of Dirac equations in static spherical space-times
Roberto Cianci, Stefano Vignolo, Luca Fabbri
We consider the Dirac equations in static spherically-symmetric space-times, and we present a type of spinor field whose structure allows the separation of elevation angle and radi…
Spinor fields in -gravity
Stefano Vignolo, Sante Carloni, Roberto Cianci +2
We present a tetrad-affine approach to gravity coupled to spinor fields of spin-1/2. After deriving the field equations, we derive the conservation law of the spin…
Reconstructing isotropic and anisotropic cosmologies
Fabrizio Esposito, Sante Carloni, Roberto Cianci +1
We present a reconstruction algorithm for cosmological models based on gravity. We specifically focus on obtaining exact Bianchi Type-I and Friedmann-Lema\^ıtre-Ro…
Axially-Symmetric Exact Solutions for Flagpole Fermions with Gravity
Roberto Cianci, Luca Fabbri, Stefano Vignolo
The Lounesto classification splits spinors in six classes: I, II, III are those for which at least one among scalar and pseudo-scalar bi-linear spinor quantities is non-zero, its s…
On the junction conditions in -gravity with torsion
Stefano Vignolo, Roberto Cianci, Sante Carloni
Junction conditions are discussed within the framework of -gravity with torsion. After deriving general junction conditions, the cases of coupling to a Dirac field and a spin…
Critical exact solutions for self-gravitating Dirac fields
Roberto Cianci, Luca Fabbri, Stefano Vignolo
We consider the Einstein-Dirac field equations describing a self-gravitating massive neutrino, looking for axially-symmetric exact solutions; in the search of general solutions, we…
