Abstract

The long-term development of the transitional regime of drift-wave turbulence is studied in a magnetized plasma column by means of the conditional-average technique. In the transitional regime, small changes in the magnetic-field strength as control parameter lead to large changes in the correlation times, indicating the existence of a critical point of an underlying nonequilibrium continuous phase transition. This and the spatiotemporal dynamics shows similarities to puff splitting, slug-gap splitting, and puff jamming.

过渡性漂波湍流中的相干泡波和鼻涕虫。

用条件平均技术研究了磁化等离子体柱中漂移波湍流过渡状态的长期发展。在过渡状态下，作为控制参数的磁场强度的微小变化会导致相关时间的大变化，表明存在一个潜在的非平衡连续相变临界点。这一现象和时空动力学表现出与抽气分裂、段塞间隙分裂和抽气干扰的相似性。

期刊介绍： Physical Review E (PRE), broad and interdisciplinary in scope, focuses on collective phenomena of many-body systems, with statistical physics and nonlinear dynamics as the central themes of the journal. Physical Review E publishes recent developments in biological and soft matter physics including granular materials, colloids, complex fluids, liquid crystals, and polymers. The journal covers fluid dynamics and plasma physics and includes sections on computational and interdisciplinary physics, for example, complex networks.
