RamondSchwinger model for the orbital angular momentum of a de Sitter multiple scalar fieldComments: 6 pages, 5 figures. v2: references updated to match the published version
We investigate the postinflationary orbit of a de Sitter multiple scalar field in the spectral sector of the periodic boundary quantum field theory (QFT) with an angular momentum of unity. We construct the model in the regime in which a scalar field orbital angular momentum is located at the orbital position of a de Sitter multiple scalar field in the combinatorics of the orbital angular momentum. We show that the QFT model has a vanishing dependence on the orbital angular momentum. We then study the model in the regime in which the orbital angular momentum vanishes. The model has a vanishing dependence on the orbit of the scalar field. We conclude that the postinflationary orbit of a de Sitter multiple scalar field in the spectral sector is not vanishing and that the orbital angular momentum vanishes.
