论文摘要
Andreev-Bashkin阻力在多个领域（例如超流体混合物，超导体和密集的核物质）中起着非常重要的作用。在这里，我们指出，拖曳现象在孤子物理学中也可能很重要，在孤子物理学中，无处不在的物体在各种领域中产生，从海啸波和光纤通信到生物系统。到目前为止，在超速原子系统中进行了富有成果的研究，由于组分间密度密度相互作用，发生了非平凡的孤子动力学。在这项工作中，我们表明，组件之间的电流耦合（Andreev-Bashkin阻力）可能会导致实质上不同的效果，而不受密度密度相互作用（例如拖动引起的深色Soliton产生）的支持。这还指出，孤子动力学可以用作实验研究无耗竭效应的工具。
Andreev-Bashkin drag plays a very important role in multiple areas like superfluid mixtures, superconductors and dense nuclear matter. Here, we point out that the drag phenomenon can be also important in physics of solitons, ubiquitous objects arising in a wide array of fields ranging from tsunami waves and fiber-optic communication to biological systems. So far, fruitful studies were conducted in ultracold atomic systems where nontrivial soliton dynamics occurred due to inter-component density-density interaction. In this work we show that current-current coupling between components (Andreev-Bashkin drag) can lead to a substantially different kind of effects, unsupported by density-density interactions, such as a drag-induced dark soliton generation. This also points out that soliton dynamics can be used as a tool to experimentally study the dissipationless drag effect.
