(2.2) We want to define an inner product of a spinor and a complex conjugate spinor; to do this we need a metric γ: ¯ ≡ ¯ A¯ γ¯ AB B. (2.3) The inverse metric is defined in the usual manner ...

WebWe studied the behavior of nonlinear spinor field within the scope of a static cylindrically symmetric space–time. It is found that the energy-momentum tensor (EMT) of the spinor field in this case possesses nontrivial non-diagonal components. The presence of non-diagonal components of the EMT imposes three-way restrictions either on the … WebThus, i is a geometrical √ −1, but it anticommutes with all spacetime vectors. By forming all distinct products of the γ µ we obtain a complete basis for the STA G 4 consisting of the 24 = 16 linearly independent elements 1,γ µ,γ µ ∧γ ν,γ µi, i. (14) To facilitate algebraic manipulations it is convenient to introduce the recip- rocal frame {γµ} defined by the …

The library contains … Webndimensional Minkowski spacetime. ( In a Minkowski spacetime, the X0, i.e., the time component, comes up with a positive signature, and the rest of spatial dimensions appear with a negative signa-ture.) In this paper, we take a null manifold in a 4-dimensional spacetime and define a parametric coordinate system on its tangent space.

Spinors and Space‐Time, Volume 2: Spinor and Twistor Methods in Space‐Time Geometry. WebWe present the emergence of a root system in six dimensions from the tetrahedra of an icosahedral core known as the 20-group (20G) within the framework of Clifford’s geometric algebra. Consequently, we establish a connection between a three-dimensional icosahedral seed, a six-dimensional (6D) Dirichlet quantized host and a higher dimensional lattice …
