Dirac fields in LRS III spacetimes: a dynamical systems analysis
Fabrizio Esposito, Sante Carloni, Stefano Vignolo
Within the covariant formalism, we investigate Locally Rotationally Symmetric (LRS) class III spacetimes sourced by a self-gravitating Dirac field expressed in polar form.…
A Covariant Distributional Approach for Junctions in Torsional Locally Rotationally Symmetric Class II Spacetimes
Ujjwal Agarwal, Sante Carloni
A rigorous framework for consistent study of junctions in a coordinate independent manner is presented. This is achieved by extending a theory of distributions in curved spacetimes…
A covariant approach to the Dirac field in LRS space-times: the case of coplanar frames
Stefano Vignolo, Giuseppe De Maria, Sante Carloni +1
We employ the polar decomposition of the Dirac field to describe it as an effective spinorial fluid. We then construct a covariant formalism for the Dirac field that avoi…
Quantized Dirac Fields in torsionful gravity: cosmological implications and links with the dark universe
Antonio Capolupo, Sante Carloni, Luca Fabbri +3
We consider a classical field in square torsion theory as a source of torsion for a quantum fermion field in FLRW metric. In the framework of QFT, we obtain vacuum contributions to…
Locally Rotationally Symmetric Spacetimes in Einstein-Cartan Theory and Their Classification
Ujjwal Agarwal, Sante Carloni
We present the complete set of covariant equations that govern the locally rotationally symmetric torsion spacetimes sourced by Weyssenhoff fluid in Einstein-Cartan-Sciama-Kibble g…
A covariant approach to the Dirac field in LRS space-times
Stefano Vignolo, Giuseppe De Maria, Luca Fabbri +1
We use the polar decomposition to describe the Dirac field in terms of an effective spinorial fluid. After reformulating all covariant equations in ``spinorial'' signature $(+ -- )…
