The intermittent excitation of geodesic acoustic mode by nonlinear Instanton of electron drift wave envelope in L-mode discharge near tokamak edge
Z. Y. Liu, Y. Z. Zhang, S. M. Mahajan +3
There are two distinct phases in the evolution of drift wave envelope in the presence of zonal flow. A long-lived standing wave phase, which we call the Caviton, and a short-lived…

The theoretical study on intermittency and propagation of geodesic acoustic mode in L- mode discharge near tokamak edge
Zhaoyang Liu, Yangzhong Zhang, Swadesh Mitter Mahajan +8
Through a systematically developed theory, we demonstrate that the motion of instanton identified in [Y. Z. Zhang, Z. Y. Liu, T. Xie, S. M. Mahajan, and J. Liu, Physics of Plasmas…
