Optics in spiral dislocation spacetime: Torsion as a geometric waveguide and frequency-filtering mechanism
Semra Gurtas Dogan, Omar Mustafa, Abdullah Guvendi +1
We present an exact analytical investigation of null trajectories and scalar wave propagation in a -dimensional spacetime containing a spiral dislocation-a topological defec…

Spiral dislocation as a tunable geometric parameter for optical responses in quantum rings
Hassan Hassanabadi, Kangxian Guo, Liangliang Lu +1
We investigate the optical and quantum mechanical properties of a charged spinless particle confined in a two-dimensional quantum ring under the simultaneous influence of a spiral…
