Topologically induced deformations of differential forms
J. M. Hoff da Silva, J. M. B. Matzenbacher, R. da Rocha
Motivated by deformations of spin structures and their geometric implications, we study a deformed exterior derivative, which is a third-order nilpotent operator. This higher-order…
Notes on obstructions in the hyperbolic Clifford algebra bundle structure
J. M. Hoff da Silva, E. Notte-Cuello
Starting from a general analysis of obstruction classes, we develop the investigation of obstructions associated with the bundle structure of the hyperbolic Clifford algebra. By ta…
Foundational aspects of spinor structures and exotic spinors
J. M. Hoff da Silva
Spinors are mathematical objects susceptible to the spacetime characteristics upon which they are defined. Not all spacetimes admit spinor structure; when it does, it may have more…
Deformations in spinor bundles: Lorentz violation and further physical implications
J. M. Hoff da Silva, R. T. Cavalcanti, G. M. Caires da Rocha
This paper delves into the deformation of spinor structures within nontrivial topologies and their physical implications. The deformation is modeled by introducing real functions t…
A note on hidden classes in spinor classification
R. J. Bueno Rogerio, R. T. Cavalcanti, C. H. Coronado Villalobos +1
The Lounesto classification is a well-established scheme for categorizing spinors based on their physical content, which are determined by their associated bilinear forms. It consi…
Non-standard Wigner doublets
F. A. da Silva Barbosa, J. M. Hoff da Silva
Guided by a conservative formulation in investigating the physical content of quantum fields, we explore non-standard Wigner classes of particles that could provide the basis for s…
