Formation of current singularity in a topologically constrained plasma
Yao Zhou, Yi-Min Huang, Hong Qin +1
Recently a variational integrator for ideal magnetohydrodynamics in Lagrangian labeling has been developed. Its built-in frozen-in equation makes it optimal for studying current sh…
Canonical symplectic particle-in-cell method for long-term large-scale simulations of the Vlasov-Maxwell system
Hong Qin, Jian Liu, Jianyuan Xiao +7
Particle-in-Cell (PIC) simulation is the most important numerical tool in plasma physics. However, its long-term accuracy has not been established. To overcome this difficulty, we…
Variational integration for ideal magnetohydrodynamics with built-in advection equations
Yao Zhou, Hong Qin, J. W. Burby +1
Newcomb's Lagrangian for ideal magnetohydrodynamics (MHD) in Lagrangian labeling is discretized using discrete exterior calculus. Variational integrators for ideal MHD are derived…
Emitting Electron Spectra and Acceleration Processes in the Jet of PKS 0447-439
Yao Zhou, Dahai Yan, Benzhong Dai +1
We investigate the electron energy distributions (EEDs) and the corresponding acceleration processes in the jet of PKS 0447439 and estimate its redshift through modeling its obs…
A Lagrangian perspective on the stability of ideal MHD equilibria with flow
Yao Zhou, J. W. Burby, Hong Qin
We take a careful look at two approaches to deriving stability criteria for ideal MHD equilibria. One is based on a tedious analysis of the linearized equations of motion, while th…
Multi-wavelength emission from 3C 66A: clues on its redshift and gamma-ray emission location
Dahai Yan, Zhonghui Fan, Yao Zhou +1
The quasi-simultaneous multi-wavelength emission of TeV blazar 3C 66A is studied by using a one-zone multi-component leptonic jet model. It is found that the quasi-simultaneous spe…
