论文摘要
在散焦培养基中具有阳性分散的Kerr培养基，二进制二元原子的二元玻璃培养基，在相分离方案中冷原子的二元玻璃介质和两种不可压缩液体的流体动力学可以帮助理论搜索独立的三维三维的三维式光学结构。在这项工作中，考虑了横向捕获（通过折射率的平滑轮廓）的光束，并提出了新的数值示例，包括``浮动掉落''，一个纵向光学涡流，具有与第二个组件的填充和滴剂的组合，并具有不均匀的曲线。还模拟了垂直于光束轴并在大距离传播的填充涡旋。 V. P. Ruban，Jetp Lett。 117（4），292（2023）; doi：10.1134/s0021364022603311
A mathematical analogy between paraxial optics with two circular polarizations of light in a defocusing Kerr medium with positive dispersion, binary Bose-Einstein condensates of cold atoms in the phase separation regime, and hydrodynamics of two immiscible compressible liquids can help in theoretical search for unknown three-dimensional coherent optical structures. In this work, transversely trapped (by a smooth profile of the refractive index) light beams are considered and new numerical examples are presented, including a ``floating drop'', a precessing longitudinal optical vortex with an inhomogeneous profile of filling with the second component, and the combination of a drop and a vortex filament. Filled vortices that are perpendicular to the beam axis and propagate at large distances have also been simulated. V. P. Ruban, JETP Lett. 117(4), 292 (2023); DOI: 10.1134/S0021364022603311
