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 ...

Type-4 spinors: transmuting from Elko to single-helicity spinors
European Physical Journal C: Particles and Fields, 2019 In this communication we briefly report an unexpected theoretical discovery which emerge from the mapping of Elko mass-dimension-one spinors into single helicity spinors. Such procedure unveils a class of spinor which is classified as type-4 spinor field

N = 4 near-horizon geometries in D = 11 supergravity
Journal of High Energy Physics, 2021 Extreme near-horizon geometries in D = 11 supergravity preserving four supersymmetries are classified. It is shown that the Killing spinors fall into three possible orbits, corresponding to pairs of spinors defined on the spatial cross-sections of the ...

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.

The Quarterly Journal of MathematicsABSTRACT We propose and develop a new method to classify orbits of the spin group ${\rm Spin}(2d)$ in the space of its semi-spinors. The idea is to consider spinors as being built as a linear combination of their pure constituents. As is well-known, two pure spinors can sum up to a pure spinor.

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

On the geometry and quantum theory of regular and singular spinors
Physics Letters BWe relate the Lounesto classification of regular and singular spinors to the orbits of the Spin(3,1) group in the space of Dirac spinors. We find that regular spinors are associated with the principal orbits of the spin group while singular spinors are ...
