Wath Time an Incident Wave Packet is Reflected?
Khaled Saaidi
We study the one dimensional time dependent Schrödinger equation for a potential step with . We obtain the wave is not instantaneously reflected, but for a few moment of t…

A Dirac Particle in a Complex Potential
Khaled Saaidi
It has been observed that a quantum mechanical theory need not to be Hermitian to have a real spectrum. In this paper we obtain the eigenvalues of a Dirac charged particle in a com…

More on Exact $\CP$-Symmetric Quantum Mechanics
Khaled Saaidi
In this article, we discussed certain properties of non-Hermitian $\CP$-symmetry Hamiltonian, and it is shown that a consistent physical theory of quantum mechanics can be built on…
