The edge of fusion plasmas is particularly important to model as this is where the plasma self-organizes to higher-energy states. From a turbulence point of view, it is a difficult region to model, often marginally stable, possibly deviating from a quasilinear approximation and subject to the influence of the material boundaries. A "transport shortfall", i.e., an underprediction of turbulence transport, has often been reported at the plasma edge. The integration of core, edge and scrape-off layer (SOL) dynamics is an area of active investigation. We have recently provided evidence for an active interplay between the confined plasma and its material boundaries. This interplay (i) cures the 'transport shortfall' at the edge of the plasma column and leads to (ii) the onset of a spontaneous, albeit moderate, transport barrier at the plasma edge, the mechanisms of which have been studied in detail. The present paper is the companion manuscript to [Dif-Pradalier, G., et al. Commun Phys 5, 229 (2022) Dif-Pradalier et al. (2022)]. We provide here comprehensive details of the techniques and procedures used in the earlier paper, including the detailed linear stability of the plasma edge, nonlinear analysis for edge turbulence, the importance of forcing and boundary conditions, and further details of the method by which causality was assessed. It also highlights the central role of diamagnetic flows in the generation of the edge transport barrier.
聚变等离子体的边缘对建模特别重要，因为这是等离子体自组织到高能态的地方。从湍流的角度来看，这是一个难以建模的区域，通常是边缘稳定的，可能偏离拟线性近似，并受到物质边界的影响。在等离子体边缘经常报道“输运不足”，即湍流输运的预估不足。核心，边缘和刮擦层（SOL）动力学的集成是一个积极的研究领域。我们最近提供的证据表明，在受限等离子体和它的物质边界之间存在积极的相互作用。这种相互作用(i)治愈了等离子体柱边缘的“传输不足”，并导致（ii）等离子体边缘自发的（尽管是适度的）传输屏障的开始，其机制已被详细研究。本文是[Dif-Pradalier， G., et al.]的合著论文。Dif-Pradalier等人[2022]。我们在这里提供了早期论文中使用的技术和程序的全面细节，包括等离子体边缘的详细线性稳定性，边缘湍流的非线性分析，强迫和边界条件的重要性，以及评估因果关系的方法的进一步细节。它还强调了反磁性流在边缘输运屏障产生中的中心作用。

The concept of electromotive field appears in various applications in space and astrophysical plasmas. A review is given on the electromotive field highlighting our current understanding of the theoretical picture and the spacecraft observations in interplanetary space. The electromotive field is a key concept to successfully close the set of turbulent magnetohydrodynamic equations and also to construct a more complete picture of space plasma turbulence. Applications to astrophysical cases (Earth magnetosphere, heliospheric shocks, interstellar medium, and relativistic jets) are also briefly introduced, as well.
