论文摘要

考虑了具有量子波动的偶极玻色菌冷凝水的扩展流体动力模型中的孤子。该模型包括浓度标量场的连续性方程,速度向量场的EULER方程,压力张量的第二等级张量的压力演化方程以及第三等级张量的演变方程。发现由量子波动的偶极部分引起的大幅度孤子溶液。它是明亮的孤儿。因此,这是颗粒数量压缩的区域。此外,它存在于排斥性的短距离交互作用。

Solitons in the extended hydrodynamic model of the dipolar Bose-Einstein condensate with quantum fluctuations are considered. This model includes the continuity equation for the scalar field of concentration, the Euler equation for the vector field of velocity, the pressure evolution equation for the second rank tensor of pressure, and the evolution equation for the third rank tensor. Large amplitude soliton solution caused by the dipolar part of quantum fluctuations is found. It appears as the bright soliton. Hence, it is the area of compression of the number of particles. Moreover, it exists for the repulsive short-range interaction.
