    Cannata, Francesco; Loffe, M.V; Nishnianidze, D. N; Mustafa, Omar (American Institute of Physics, 2010)
    We study a quantum model with nonisotropic two-dimensional oscillator potential but with additional quadratic interaction x1x2x1x2 with imaginary coupling constant. It is shown that for a specific connection between coupling ...

    Sakallı, İzzet; Al-Badawi, Ahmad (Canadian Journal of Physics, NRC Research Press, 2009)
    Exact solutions of a massive complex scalar field equation in the geometry of a Garfinkle-Horowitz-Strominger (stringy) black hole with magnetic charge is explored. The separated radial and angular parts of the wave equation ...
