PT symmetry, Cartan decompositions, Lie triple systems and Krein space related Clifford algebras
Uwe Guenther, Sergii Kuzhel
Gauged PT quantum mechanics (PTQM) and corresponding Krein space setups are studied. For models with constant non-Abelian gauge potentials and extended parity inversions compact an…
