Paraxial propagation in disclinated amorphous media
Mohammad Mehrafarin, Shima Gholam-Mirzaei
We study paraxial beam propagation along the wedge axis of a disclinated amorphous medium. The defect-induced inhomogeneity results in Berry phase and curvature that are affected b…

Paraxial propagation in amorphous optical media with screw dislocation
L. Mashhadi, M. Mehrafarin
We study paraxial beam propagation parallel to the screw axis of a dislocated amorphous medium that is optically weakly inhomogeneous and isotropic. The effect of the screw disloca…
