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…
Simulating Pitch Angle Scattering Using An Explicitly Solvable Energy Conserving Algorithm
Xin Zhang, Yichen Fu, Hong Qin
Particle distribution functions evolving under the Lorentz operator can be simulated with the Langevin equation for pitch angle scattering. This approach is frequently used in part…
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…
