Doubled of Minkowski space and spinor wave function

Click For Summary
SUMMARY

The discussion centers on the concept of an 8-dimensional Finsler space that preserves the metric form \( S^2 = tt^*-xx^*-yy^*-zz^* \), which represents the doubled Minkowski space. It explores particle-like solutions localized on the world line of this space, characterized by a spinor wave function. The spinor wave function is defined with components \( \psi_1, \psi_2, \psi_3, \psi_4 \) and incorporates the path length features in the space defined by coordinates \( (t, x, y, z, t^*, x^*, y^*, z^*) \). Additionally, it discusses the implications of symmetry in particle-like solutions and the conditions under which internal symmetry is broken.

First of all note that 8-dinensional Finsler space (t,x,y,z,t^*,x^*,y^*,z^*) preserving the metric form
\begin{equation}
S^2 = tt^*-xx^*-yy^*-zz^*,
\end{equation}
actually presents doubled of the Minkowski space.

Then the solution with one-dimensional feature localized on the world line of doubled of Minkowski space (x, y, z, t,t^*,x^*,y^*,z^*), which in the distance from it tends to the vacuum potential, should be considered as particle-like solutions. Moreover, if we are interested in particle-like solutions in which the static part of the line potential features has symmetry of the equator of seven-sphere, and the dynamic characteristics of the line is wound on this equator, then the space which is orthogonal to this line (or rather - a congruence of lines) features can be represented by spinor wave function:
\begin{equation}
\begin{cases}
\psi_1= \frac{z_1}{|z|}e^{iS},\\
\psi_2= \frac{z_2}{|z|}e^{iS},\\
\psi_3= \frac{z_3}{|z|}e^{iS},\\
\psi_4= \frac{z_4}{|z|}e^{iS},
\end{cases}
\end{equation}
where (z_j = x_{2j- 1} + ix_{2j})_4 --- a point north pole of the sphere with radius |z| = \sqrt{z_1\bar{z}_1 + \cdots + z_4\bar{z}_4}, and S = k_{x}x + k_{y}y + k_{z}z-k_{t}t --- this is the path length features in the space (t, x, y , z, t^*, x^*, y^*, z^*). Note also that if we are interested in particle-like solutions with the symmetry of the pseudo-sphere radius \sqrt{z_1\bar{z}_1 + z_2\bar{z}_2 - z_3\bar{z}_3-z_4\bar{z}_4}, but their internal symmetry is broken by the inequality \sqrt{z_1\bar{z}_1 + z_2\bar{z}_2} \gg\sqrt{z_3\bar{z}_3 + z_4\bar{z}_4}, we can limit the two-component spinor describing the symmetry on three-dimensional sphere with radius \sqrt{z_1\bar{z}_1 + z_2\bar{z}_2}.

Whether it is worth discussing?

"Supernovae evidence for foundational change to cosmological models" https://arxiv.org/pdf/2412.15143 The paper claims: We compare the standard homogeneous cosmological model, i.e., spatially flat ΛCDM, and the timescape cosmology which invokes backreaction of inhomogeneities. Timescape, while statistically homogeneous and isotropic, departs from average Friedmann-Lemaître-Robertson-Walker evolution, and replaces dark energy by kinetic gravitational energy and its gradients, in explaining...
