Fundamental Theory of Torsion Gravity
Universe, 2021 In this work, we present the general differential geometry of a background in which the space–time has both torsion and curvature with internal symmetries being described by gauge fields, and that is equipped to couple spinorial matter fields having spin

Algebraic and Dirac–Hestenes spinors and spinor fields [PDF]
Journal of Mathematical Physics, 2004 Almost all presentations of Dirac theory in first or second quantization in physics (and mathematics) textbooks make use of covariant Dirac spinor fields. An exception is the presentation of that theory (first quantization) offered originally by Hestenes and now used by many authors. There, a new concept of spinor field (as a sum of nonhomogeneous even

Spinor-Like Hamiltonian for Maxwellian Optics
EPJ Web of Conferences, 2016 Background. Spinors are more special objects than tensors. Therefore spinors possess more properties than the more generic objects such as tensors. The group of Lorentz two-spinors is the covering group of the Lorentz group. Purpose.

Opening the Pandora’s box of quantum spinor fields
European Physical Journal C: Particles and Fields, 2018 Lounesto’s classification of spinors is a comprehensive and exhaustive algorithm that, based on the bilinears covariants, discloses the possibility of a large variety of spinors, comprising regular and singular spinors and their unexpected applications ...

Invariant Spinors on Homogeneous Spheres [PDF]
, 2023 Using the characterization of the spin representation in terms of exterior forms, we give a complete classification of invariant spinors on the nine homogeneous realizations of the sphere $S^n$.

Journal of Physics A: Mathematical and General, 2004 Solutions to the four-dimensional Euclidean Weyl equation in the background of a general JNR N-instanton are known to be normalisable and regular throughout four-space. We show that these solutions are asymptotically given by a linear combination of simple singular solutions to the free Weyl equation, which can be interpreted as localised spinors. The `

Spinors in (Anti-)de Sitter Space
Journal of High Energy Physics, 2023 We explore analytical aspects of correlators involving Dirac spinors in d + 1-dimensional de Sitter space. Adapting the formalism of Sleight and Taronna, we show how to relate processes involving fermions in the in-in formalism to equivalent Witten ...

Killing spinors from classical r-matrices [PDF]
, 2019 In this article we summarize the interplay between supersymmetry and integrable deformations of superstring theory backgrounds. We start from a brief review of a recipe for the preserved Killing spinors in TsT deformed backgrounds. Then a few examples in

Universe, 2020 We show Zeeman-like splitting in the energy of spinors propagating in a background gravitational field, analogous to the spinors in an electromagnetic field, otherwise termed the Gravitational Zeeman Effect.
