我们研究在具有立方-五次非线性和单环或多环势的体波导中，沿螺旋（螺旋旋转）和直线路径传播的孤子的存在性与动力学特性。输入采用的是带有单个或多个相位奇点（支点）且偏离波导轴的涡旋光束。单个离轴支点会产生单环螺旋孤子，其结构可为闭合或开放（分裂）环；带有多个离轴支点的涡旋光束则会产生多环、多芯和/或多分裂结构的复杂态。多芯/分裂孤子沿螺旋通道或与传播轴平行的直线路径传播。通过施加具有合适角速度的扭矩，可精确调整螺旋性的符号与周期。
英文摘要
We address the existence and dynamics of solitons propagating along helical (spiral-rotating) and straight trajectories in the bulk waveguide with the cubic-quintic nonlinearity and a single- or multi-ring potential. The input is taken as a vortex beam with a single or multiple phase singularities (pivots), displaced from the waveguide's axis. The single off-axis pivot creates a one-ring helical soliton, with a closed or open (split) ring structure. The vortex beams with multiple off-center pivots give rise to complex states with multi-ring, multi-core, and/or multi-split structures. The multi-core/split solitons propagate along helical channels, or straight ones, which are parallel to the propagation axis. The sign and period of the helicity can be precisely adjusted by applying a torque with an appropriate angular velocity.
