Abstract

In this work, we analyze the scattering of fermionic quasi-particles in the presence of radial disgyrations and symmetric vortices in the superfluid 3He–A. We consider a Volovik analog model for the description of these defects and investigate the scattering of fermionic quasi-particles in this background. Furthermore, we solve the massless Dirac equation employing this methodology to gain comprehensive insights into the scattering phenomena and its dependence on the geometric properties. These results validate the optical theorem and highlight the role of defect topology in the scattering process. [ABSTRACT FROM AUTHOR]
