Finite-gap systems, tri-supersymmetry and self-isospectrality
Francisco Correa, Vit Jakubsky, Mikhail S. Plyushchay
We show that an n-gap periodic quantum system with parity-even smooth potential admits isospectral super-extensions. Each is described by a tri-supersymmetry that originate…
Self-isospectrality, special supersymmetry, and their effect on the band structure
Francisco Correa, Vit Jakubsky, Luis-Miguel Nieto +1
We study a planar model of a non-relativistic electron in periodic magnetic and electric fields that produce a 1D crystal for two spin components separated by a half-period spacing…
Relativistic vector bosons and PT-symmetry
Jaroslav Smejkal, Vit Jakubsky, Miloslav Znojil
Relativistic massive bosons with spin one are considered in several quantization schemes. In all of them the system is shown described by a non-Hermitian Hamiltonian and helicity o…
