Gyrokinetic theory
WebJan 1, 1996 · The U.S. Department of Energy's Office of Scientific and Technical Information WebJan 18, 2007 · In its most general form, gyrokinetic theory is about a symmetry, called gyro-symmetry, for magnetized plasmas, and the 1-form {gamma} again uniquely defines the gyro-symmetry. The objective is to decouple the gyro-phase dynamics from the rest of particle dynamics by finding the gyro-symmetry in {gamma}.
Gyrokinetic theory
Did you know?
WebGyrokinetics is a popular approach to investigate turbulent phenomena in magnetized plasmas such as those of fusion devices (Brizard & Hahm 2007; Cary & Brizard 2009 ). Gyrokinetics is well suited in scenarios where the microscopic dynamics are subject to the gyrokinetic ordering. WebThe development of low-frequency gyrokinetic theory was motivated by the need to describe complex plasma dynamics over time scales that are long compared to the …
