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分支，量子等离子体动力学（QPD），将应用于极端磁场和密度条件下的等离子体、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丝化激发的大量耦合、局部、瞬态、异常电阻区域。该模型将包括阿尔芬尼锋的非局域能量释放、磁零点处的 3D 重联以及电子的整体激励。 '连贯性？相干发射源的变化将被量化，并且将制定一个解释高度间歇性波增长的模型。
