Experimental & Theoretical Plasma Physics

Welcome

By combining sophisticated laboratory experiments with advanced theoretical techniques, we study fundamental plasma physics issues relevant to astrophysics, solar physics, planetary rings, magnetospheres, space propulsion, and controlled thermonuclear fusion. A central unifying theme is that plasma concepts are extremely scalable so our research provides new insights for all the above areas.

The paper by  Magnus Haw and Paul Bellan MHD collimation mechanism in arched flux ropes characterized using volumetric, time‐dependent B‐vector measurements is an “Editor’s Highlight” in Geophysical Research Letters.
Young Dae Yoon gave an invited talk at the 2017 American Physical Society Division of Plasma Physics annual meeting on a new way of explaining fast magnetic reconnection. The talk is A generalized two-fluid picture of non-driven collisionless reconnection and its relation to whistler waves
Paul Bellan gave a tutorial talk at the 2017 American Physical Society Division of Plasma Physics annual meeting on Experiments and models of MHD jets and their relevance to astrophysics and solar physics.
Measurements made by the MMS spacecraft reported by Gershman et al. in the paper Wave-particle energy exchange directly observed in a kinetic Alfvén-branch wave  in Nature Communications validate the method proposed by Paul Bellan  in the paper  Revised Single-Spacecraft Method for Determining Wavevector k and Resolving Space-time Ambiguity.  This method shows how a single spacecraft can measure the  wavelength and direction of a low-frequency plasma wave so four spacecraft are not needed as was previously presumed.
