arXiv:1007.2094v3 [quant-ph] 20 Jul 2010 Position-dependent-mass; Cylindrical coordinates, separability, exact solvability, and PT -symmetry Omar Mustafa Department of Physics, Eastern Mediterranean University, G Magusa, North Cyprus, Mersin 10,Turkey E-mail: omar.mustafa@emu.edu.tr Tel: +90 392 630 1314, Fax: +90 392 3651604 November 27, 2018 The kinetic energy operator with position-dependent-mass in cylin- drical coordinates is obtained. The separability of the corresponding Schr¨ odinger equation is discussed within radial cylindrical mass settings. Azimuthal symmetry is assumed and spectral signatures of various z - dependent interaction potentials (Hermitian and non-Hermitian PT -symmetric) are reported. PACS codes: 03.65.Ge, 03.65.Ca Keywords: Position-dependent-mass, cylindrical setting, separability, exact solvability, PT -symmetry. 1 Abstract
