The topology, geometry, and angular momentum of cold plasma waves
Eric Palmerduca, Hong Qin
It was recently discovered that plasma waves possess topologically protected edge modes, indicating the existence of topologically nontrivial structures in the governing equations.…
Wave Topology in Hall MHD
Alejandro Mesa Dame, Hong Qin, Eric Palmerduca +1
Hall Magnetohydrodynamics (HMHD) extends ideal MHD by incorporating the Hall effect via the induction equation, making it more accurate for describing plasma behavior at length sca…
Spin-weighted spherical harmonics as massless angular momentum eigenstates and their role in obstructing spin-orbital decompositions
Eric Palmerduca, Hong Qin
We show that for massless helicity particles, the angular momentum eigenstates are given in an appropriate coordinate system by the spin-weighted spherical harmonics ${_{-h}Y_{…
Zero curvature is a necessary and sufficient condition for a spin-orbital decomposition
Eric Palmerduca, Hong Qin
There has been an extended debate regarding the existence of a spin-orbital decomposition of the angular momentum of photons and other massless particles. It was recently shown tha…
