The effect of Dirac phase on acoustic vortex in media with screw dislocation
arXiv:1306.3038 · doi:10.1016/j.physleta.2013.05.014
Abstract
We study acoustic vortex in media with screw dislocation using the Katanaev-Volovich theory of defects. It is shown that the screw dislocation affects the beam's orbital angular momentum and changes the acoustic vortex strength. This change is a manifestation of topological Dirac phase and is robust against fluctuations in the system.
