Exotic Spinorial Structure and Black Holes in General Relativity
Dino Beghetto, Rogerio T. Cavalcanti, Julio M. Hoff da Silva
We explore different (and complementary) views of spinors and their exotic counterparts, linking the very existence of the later to the presence of black holes. Moreover, we invest…
Higher-order theories from the minimal length
Marco Dias, Julio M. Hoff da Silva, Eslley Scatena
We show that the introduction of a minimal length in the context of non-commutative spacetime gives rise (after some considerations) to higher-order theories. We then explicitly de…
From Dirac spinor fields to ELKO
Roldao da Rocha, Julio M. Hoff da Silva
Dual-helicity eigenspinors of the charge conjugation operator (ELKO spinor fields) belong, together with Majorana spinor fields, to a wider class of spinor fields, the so-called fl…
Shortcuts in particle production in a toroidal compactified spacetime
Julio M. Hoff da Silva, Roldao da Rocha
We investigate the particle production in a toroidal compactified spacetime due to the expansion of a Friedmann cosmological model in R3 x S1 outside a U(1) local cosmic string. Th…
