The effect of Dirac phase on acoustic vortex in media with screw dislocation
چکیده انگلیسی


• We study acoustic vortex in media with screw dislocation.
• We use the framework of geometric theory of defects.
• Presence of dislocation changes the acoustic vortex strength.
• There is a similarity with the Aharanov–Bohm effect.
• Change of the acoustic vortex strength is robust against fluctuations.

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 beamʼs 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.
