  • Spherical-separability of Non-Hermitian Hamiltonians and Pseudo-PT -symmetry 
    Mustafa, Omar; Mazharimousavi, Seyed Habib (Springer, 2009-01)
    Non-Hermitian but PϕTϕ-symmetrized spherically-separable Dirac and Schrödinger Hamiltonians are considered. It is observed that the descendant Hamiltonians Hr , Hθ , and Hϕ play essential roles and offer some “user-feriendly” ...
  • Supersymmetric Extension of Non-Hermitian su(2) Hamiltonian and Supercoherent States 
    Mustafa, Omar (SIGMA, 2010)
    A new class of non-Hermitian Hamiltonians with real spectrum, which are written as a real linear combination of su(2) generators in the form H=ωJ3+αJ−+βJ+, α≠β, is analyzed. The metrics which allows the transition to the ...
  • η-weak-pseudo-Hermiticity generators and exact solvability 
    Mustafa, Omar; Mazharimousavi, Habib S. (Springer, 2006)
    Exact solvability of some non-Hermitian η-weak-pseudo-Hermitian Hamiltonians is explored as a byproduct of η-weak-pseudo-Hermiticity generators. A class of V (x) = V (x) + i W (x) potentials is considered, where the imaginary ...
  • η-Weak-Pseudo-Hermiticity Generators and Radially Symmetric Hamiltonians 
    Mustafa, Omar; Mazharimousavi, Seyed Habib (SPRINGER/PLENUM PUBLISHERS, 2008-07)
    A class η-weak-pseudo-Hermiticity generators for spherically symmetric non- Hermitian Hamiltonians are presented. An operators-based procedure is introduced so that the results for the 1D Schrödinger Hamiltonian may very ...
