具有集体、电子和孤立子密度和电流的电荷密度波中的多流体流体动力学
Multi-fluid hydrodynamics in charge density waves with collective, electronic, and solitonic densities and currents
摘要：
我们提出了一个一般的方案来接近时空演化的变形，电流，和电场的电荷密度波的出现有关的本征拓扑缺陷：位错，它们的环或对，和孤子。我们推导了考虑集体模、电场、正常电子和本征缺陷的多流体流体动力学的一般方程。这些方程可以允许研究注入的载流子从正常电子到电荷密度波的新周期的转变，在约束几何形状中的集体运动，以及塑性状态和流动。作为一个应用，我们提出了一个孤立的位错线周围的场分布的解析和数值解的非线性屏蔽制度的气体相孤子。
英文摘要：
We present a general scheme to approach the space - time evolution of deformations, currents, and the electric field in charge density waves related to appearance of intrinsic topological defects: dislocations, their loops or pairs, and solitons. We derive general equations for the multi-fluid hydrodynamics taking into account the collective mode, electric field, normal electrons, and the intrinsic defects. These equations may allow to study the transformation of injected carriers from normal electrons to new periods of the charge density wave, the collective motion in constrained geometry, and the plastic states and flows. As an application, we present analytical and numerical solutions for distributions of fields around an isolated dislocation line in the regime of nonlinear screening by the gas of phase solitons.
