Linear Gyrokinetic Simulations of Micro-tearing Mode: Local versus Global
Yifei Liu, Haotian Chen, Yao Yao +3
A systematic comparison of local and global linear gyrokinetic simulations of micro-tearing modes (MTMs) is performed using the GENE code. The analysis spans diverse plasma paramet…
Stability for multiple Lamb dipoles
Ken Abe, In-Jee Jeong, Yao Yao
In the class of nonnegative vorticities on the half-plane, we establish the Lyapunov stability of finite sums of Lamb dipoles under the initial assumptions that the dipoles are suf…
On the electromagnetic effects of collisionless trapped-electron modes
Yao Yao, Haotian Chen, Yang Chen +2
We present a linear gyrokinetic theory for the electromagnetic collisionless trapped-electron mode (CTEM). It is found that the weak electromagnetic effects of CTEMs originate from…
Superlinear gradient growth for 2D Euler equation without boundary
In-Jee Jeong, Yao Yao, Tao Zhou
We consider the vorticity gradient growth of solutions to the two-dimensional Euler equations in domains without boundary, namely in the torus and the whole plane…
