Fermion scattering by a Schwarzschild black hole
Sam Dolan, Chris Doran, Anthony Lasenby
We study the scattering of massive spin-half waves by a Schwarzschild black hole using analytical and numerical methods. We begin by extending a recent perturbation theory calculat…
Events and cosmological spaces through twistors in the geometric (Clifford) algebra formalism
Elsa Arcaute, Anthony Lasenby, Chris Doran
Events in Minkowski space-time can be obtained from the intersection of two twistors with no helicity. These can be represented within the geometric (Clifford) algebra formalism, i…
A representation of twistors within geometric (Clifford) algebra
Elsa Arcaute, Anthony Lasenby, Chris Doran
In previous work by two of the present authors, twistors were re-interpreted as 4-d spinors with a position dependence within the formalism of geometric (Clifford) algebra. Here we…
