Role of Magnetic Field in the Redistribution of Turbulence from Large-Scale Structures to Small-Scale Fluctuations
Tanmay Karmakar, Rosh Roy, Lavkesh Lachhvani +5
Magnetized plasmas with equilibrium density gradients support drift-wave turbulence, which is often regulated by self-generated zonal flows. In this work, we experimentally examine…

Transition from Zonal Flows to Streamer like structures and associated edge Fluctuations
Tanmay Karmakar, Rosh Roy, Lavkesh Lachhvani +5
We report experimental observations of a controlled transition from a zonal-flow (ZF) dominated regime to a coexistence regime of ZFs and streamers, and finally to a streamer-domin…

Experimental observation of drift acoustic cnoidal waves in a magnetized plasma
Tanmay Karmakar, Rosh Roy, Lavkesh Lachhvani +5
We report the experimental observation of highly nonlinear coherent structures in a linear magnettized plasma characterized by a strong background density gradient and significant…
