Collisionless Resonances Set the Size of a Weyl Exceptional Ring
Xianhao Rao, Hong Li, Xuan Sun
Eliminating continuum degrees of freedom converts conservative dynamics into a dispersive, non-Hermitian response whose topology need not represent the causally selected kinetic dy…
Phase-Space Topology and Spectral Flow in Screened Magnetized Plasmas
Xianhao Rao, Adil Yolbarsop, Hong Li +1
Topological wave phenomena in continuous media are fundamentally challenged by unbounded spectra and the absence of a compact Brillouin zone, which obstruct conventional bulk--inte…
Symmetry-Driven Bulk-Edge Correspondence in Electron Magnetofluids at Finite Temperature
Xianhao Rao, Adil Yolbarsop, Hong Li +1
We present a theoretical framework connecting the pseudo-Chern number in momentum space to the spectral flow index in phase space for continuous media, with specific applications t…
Relaxation model for a homogeneous plasma with spherically symmetric velocity space
Yanpeng Wang, Jianyuan Xiao, Xianhao Rao +3
We derive the transport equations from the Vlasov-Fokker-Planck equation when the velocity space is spherically symmetric. The Shkarofsky's form of Fokker-Planck-Rosenbluth collisi…
