Hopfion-like solutions in de Sitter spacetime

Published 21 Mar 2024 in gr-qc | (2403.14245v1)

Abstract: We construct electromagnetic field with non-trivial topological properties on de Sitter background. The field is closely related with Hopf fibration. We analyze energy, angular momentum and topological charges for this solution. The paper is a generalization of CQG \textbf{35} (2018), no. 24, 245010 to de Sitter spacetime.
