The Dirac equation in (split-)octonions: origins, variants, and modern context
J. Köplinger
Octonions and split-octonions have been used to express the Dirac equation in physics in several conceptually distinct ways. This review organizes them into four groups: the 2-fact…

Operational reconstruction of Feynman rules for quantum amplitudes via composition algebras
Jens Köplinger, Michael Habeck, Philip Goyal
This article explores an operational model for transition amplitudes between measurements proposed by Goyal et al. within the quantum reconstruction program. To classify suitable a…

Phenomenology from Dirac equation with Euclidean-Minkowskian "gravity phase"
Jens Köplinger
Over the past decades, many authors advertised models on complexified spacetime algebras for use in describing gravity. This work aims at providing phenomenological support to such…
