INTRODUCTION AUX SYSTEMES QUANTIQUES NON-HERMITIQUES: PT-symétrie et pseudo Hermiticité
Maamache Mustapha
In recent decades, an important shift has taken place with the growing role of non-Hermitian quantum mechanics. What makes this framework remarkable is that the eigenvalues of the…

Comment on "the quantum dynamics for general time-dependent three coupled oscillators"
Zerimeche Rahma, Mana Naima, Maamache Mustapha
In a recent paper, Hassoul et al.[1], the authors proposed an analysis of the quantum dynamics for general time-dependent three coupled oscillators through an approach based on the…

Non-Hermitian Hamiltonian beyond PT-symmetry for time-dependant SU(1,1) and SU(2) systems -- exact solution and geometric phase in pseudo-invariant theory
Nadjat Amaouche, Maroua Sekhri, Rahma Zerimeche +2
We investigate in this paper time-dependent non-Hermitian Hamiltonians, which consist respectively of SU(1,1) and SU(2) generators. The former Hamiltonian is PT symmetric but the l…
