Abstract

A complex Lorenz system for convection due to interchange instability in collisional plasmas is derived from the classical two-fluid equations, including, among others, the effects of magnetic field curvature, finite ion gyroradius, and compressibility. The correspondences and differences between the presently derived system and the Lorenz system are discussed. For a wide regime of physical parameters the system is found to evolve towards a nonlinear equilibrium, but chaotic behavior is observed for the regime in which the real Lorenz system is chaotic.

APS and the Physical Review Editorial Office Continue to Support Researchers

COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access.

We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. And we hope you, and your loved ones, are staying safe and healthy.

Ways to Access APS Journal Articles Off-Campus

Many researchers now find themselves working away from their institutions and, thus, may have trouble accessing the Physical Review journals. To address this, we have been improving access via several different mechanisms. See Off-Campus Access to Physical Review for further instructions.
