Two-fluid effects on the nonlinear dynamics of RFP relaxation
Wentan Yan, Ping Zhu, Hong Li +2
This study investigates the role of two-fluid effects during magnetic relaxation in reversed-field pinch (RFP) plasmas. Within the multiple-helicity (MH) regime, two-fluid simulati…
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…
Enhanced dynamo drive for the sawtooth relaxation process due to non-uniform resistivity distribution in a reversed field pinch
Wentan Yan, Ping Zhu, Hong Li +3
In this work, we use the three-dimensional resistive MHD code NIMROD to investigate the impact of resistivity inhomogeneity on the sawtooth process of an reversed field pinch (RFP)…
