A new branch of theoretical physics, quantum plasmadynamics (QPD), will be applied to plasmas under extreme conditions of magnetic field and density, to plasma-neutrino effects and nonlinear radiation. Magnetic energy dissipation in solar flares will be attributed to a large number of coupled, local, transient, anomalously resistive regions excited by current filamentation. The model will include nonlocal energy release at Alfvenic fronts, 3D reconnection at magnetic nulls, and bulk energization of electrons. `Coherence? in sources of coherent emission will be quantified and a model for its interpretation for highly intermittent wave growth will be formulated.

理论物理学的一个新的分支，量子等离子体动力学（QPD），将被应用于磁场和密度极端条件下的等离子体，等离子体中微子效应和非线性辐射。 太阳耀斑中的磁能耗散归因于电流激励激发的大量耦合的、局部的、瞬态的、负阻的区域。该模型将包括非本地的能量释放Alfvenic前线，3D重联在磁零点，和大量的电子。 “连贯性？将对相干发射源进行量化，并将制定一个解释高度间歇性波浪增长的模型。
