Non-linear Supersymmetry for non-Hermitian, non-diagonalizable Hamiltonians: I. General properties
A. A. Andrianov, F. Cannata, A. V. Sokolov
We study complex potentials and related non-diagonalizable Hamiltonians with special emphasis on formal definitions of associated functions and Jordan cells. The nonlinear SUSY for…

Construction of PT-asymmetric non-Hermitian Hamiltonians with CPT-symmetry
Emanuela Caliceti, Francesco Cannata, Miloslav Znojil +1
Within CPT-symmetric quantum mechanics the most elementary differential form of the charge operator C is assumed. A closed-form integrability of the related coupled differential se…
