Dirac相位对螺位错介质中声涡旋的影响
The effect of Dirac phase on acoustic vortex in media with screw dislocation
摘要：
本文利用Katanaev-Volovich缺陷理论研究了螺型位错介质中的声涡旋。结果表明，螺旋位错影响了光束的轨道角动量，改变了声涡旋强度。这种变化是拓扑狄拉克相位的表现，并且对系统中的波动具有鲁棒性。
英文摘要：
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.
