Topological phases and bulk-edge correspondence of magnetized cold plasmas
Yichen Fu, Hong Qin
Plasmas have been recently studied as topological materials. However, a comprehensive picture of topological phases and topological phase transitions in cold magnetized plasmas is…
Spontaneous and explicit parity-time-symmetry breaking in drift wave instabilities
Hong Qin, Yichen Fu, Alexander S. Glasser +1
A method of Parity-Time (PT)-symmetry analysis is introduced to study the high dimensional, complicated parameter space of drift wave instabilities. We show that spontaneous PT-sym…
An Explicitly Solvable Energy-Conserving Algorithm for Pitch-Angle Scattering in Magnetized Plasmas
Yichen Fu, Xin Zhang, Hong Qin
We develop an Explicitly Solvable Energy-Conserving (ESEC) algorithm for the Stochastic Differential Equation (SDE) describing the pitch-angle scattering process in magnetized plas…
The Physics of Spontaneous Parity-Time Symmetry Breaking in the Kelvin-Helmholtz Instability
Yichen Fu, Hong Qin
We show that the dynamics, in particular the Kelvin-Helmholtz (KH) instability, of an inviscid fluid with velocity shear admits Parity-Time (PT) symmetry, which provides a physical…
