WebTo split spinor connection into Keller connection $\Upsilon_\mu\in\Lambda^1$ and pseudo-vector potential $\Omega_\mu\in\Lambda^3$ by Clifford algebra not only makes the calculation simpler, but also highlights their different physical meanings. The representation of the new spinor connection is dependent only on the metric, but not on the Dirac ... WebFeb 6, 2024 · (16) The solution presented in (15) along with the Lagrangian in (8) is quite a miracle. We have reproduced Einstein’s field equations by assuming spinors have their own metric and affine connection, in effect their own geometry, and have demonstrated that doing so leads to not only curved space-time, but electromagnetism as a geometric effect …
Webpart of the Lorentz connection. The projective invariance of the spinor connection allows to introduce gauge fields interacting with spinors. We also derive the relation between the curvature spinor and the curvature tensor for a general connection. Keywords Spinor · Tetrad · Lorentz connection · Spinor connection · Fock–Ivanenko ...

WebA classical pp-wave is a 4-dimensional Lorentzian spacetime which admits a nonvanishing parallel spinor field; here the connection is assumed to be Levi-Civita. This definition was generalised in our previous work to metric compatible spacetimes with torsion and used to construct new explicit vacuum solutions of quadratic metric-affine gravity ... WebJan 18, 2024 · A spin connection is then a connection on this principal bundle. It is equivalently a spin algebra valued connection form. And as the algebra of covering groups …
WebFor the covariant spinor derivative we need to introduce a connection which can parallel transport a spinor. Such a connection takes values in the Lie-algebra of the group the spinor transforms under. Then we have: D i ψ = ∂ i ψ + g A i I T I ψ. Here T I are the generators of the lie-algebra and are matrix valued.

The value of the invariant on a spin c structure is easiest to define when the moduli space is zero-dimensional (for a generic metric). In this case the value is the number of elements of the moduli space counted with signs. shows birmingham hippodromeIn differential geometry and mathematical physics, a spin connection is a connection on a spinor bundle. It is induced, in a canonical manner, from the affine connection. It can also be regarded as the gauge field generated by local Lorentz transformations.
