Stochastic simulation of collisions using high-order weak convergence algorithms
Wentao Wu, Jian Liu, Hong Qin
Electron collisions, described by stochastic differential equations (SDEs), were simulated using a second-order weak convergence algorithm. Using stochastic analysis, we constructe…

The role of magnetic moment in the collisionless pitch-angle scattering of runaway electrons
Chang Liu, Hong Qin, Eero Hirvijoki +2
Recently, the validity of the guiding-center approach to model relativistic runaway electrons in tokamaks has been challenged by full-orbit simulations that demonstrate the breakdo…

What breaks parity-time-symmetry? -- pseudo-Hermiticity and resonance between positive- and negative-action modes
Ruili Zhang, Hong Qin, Jianyuan Xiao +1
It is generally believed that Parity-Time (PT)-symmetry breaking occurs when eigenvalues or both eigenvalues and eigenvectors coincide. However, we show that this well-accepted pic…
