Majorana interface states in anisotropic and tilted Dirac and Weyl systems
The work develops analytical frameworks to understand how anisotropy and band tilting modify Majorana boundary modes in Dirac and Weyl systems. It derives closed expressions for topological invariants, localization length, and propagation velocity in anisotropic 2D Dirac systems. The findings provide design principles for engineering Majorana channels through control over interface orientation and band tilt effects.
