# Position-dependent-mass; Cylindrical coordinates, separability, exact solvability, and PT -symmetry 

Department of Physics, Eastern Mediterranean University, 

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. 

Keywords: Position-dependent-mass, cylindrical setting, separability, exact solvability, PT -symmetry.
