| contents | We investigate the photonic spin Hall effect (PSHE) and the Goos-Hänchen shift (GH shift) in semi-Dirac
materials. Through theoretical modeling, we demonstrate that the anisotropic dielectric function in semi-Dirac
materials play a critical role in determining the magnitude and polarity of these optical displacements. Further more, by utilizing the unidirectional drift of massless Dirac electrons in Semi-Dirac materials, we systematically
reveal how the drift velocity and direction modulate the behavior of optical displacements. The results indicate
that semi-Dirac materials provide a versatile platform for controlling spin-dependent photonic phenomena with
their material anisotropy and carrier transport. This work opens a new avenue for designing advanced photonic
devices with tunable optical responses, particularly with significant application potential in quantum information
processing and topological photonics. |
