"Drift Wave Turbulence in Asymmetric Reconnection"

by Lora McMurtrie

Friday, November 22, 2013 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Professor James Drake

An important feature in collisionless magnetic reconnection is the development of sharp discontinuities along the separatrices bounding the Alfvenic outflow. The typical scale length of these features is ρs (the Larmor radius based on the sound speed) for guide field reconnection. Temperature gradients in the inflowing plasma can lead to instabilities at these separatrices, specifically drift wave turbulence. We present 2D PIC simulations of drift wave turbulence to investigate scaling properties and growth rates.
