论文摘要
暗孤子的一般理论依赖于排斥的相互作用，因此预测了形成深色苏里顿结合状态的不可能。该预测的一个重要例外是在非本地非线性培养基中观察结合的孤子。在这里，我们报告说，尽管相互作用是完全局部的，但激子 - 波利顿超流体也可以维持深色的分子。通过一种新颖的所有光学技术，我们创建了两个深色孤子，并彼此结合以形成一个非常规的深色 - 丝孔分子。我们证明，这种结构的稳定性和两个深色 - 岩石之间的分离距离紧密连接到北极流体的驱动性质。
The general theory of dark solitons relies on repulsive interactions and therefore predicts the impossibility to form dark-soliton bound states. One important exception to this prediction is the observation of bound solitons in non-local nonlinear media. Here, we report that exciton-polariton superfluids can also sustain dark-soliton molecules although the interactions are fully local. With a novel all optical technique, we create two dark solitons and bind them to each other to form an unconventional dark-soliton molecule. We demonstrate that the stability of this structure and the separation distance between two dark-solitons is tightly connected to the driven-dissipative nature of the polariton fluid.
