标题： Magnetic soliton molecules in binary condensates

摘要： 两组分玻色-爱因斯坦凝聚体在可混相区域可以支持极化孤立波，称为磁孤子。 通过计算两个磁孤子之间的相互作用势能，我们阐明了束缚态（或分子）形成的机制和条件，并通过动态模拟验证了这些预测。 我们分析确定了由两个相反极化孤子组成的束缚态的解离能量，并发现与全数值模拟结果有良好一致性。 束缚态之间——无论是与其他束缚态还是与单个孤子——的碰撞会产生引人入胜的动力学行为。 值得注意的是，一对束缚态之间的碰撞表现出类似偶极子的行为。 我们预计，这样的束缚态及其丰富的碰撞动力学行为，目前的实验能力是可以实现的。 显示英文摘要

摘要： Two-component Bose-Einstein condensates in the miscible phase can support polarization solitary waves, known as magnetic solitons. By calculating the interaction potential between two magnetic solitons, we elucidate the mechanisms and conditions for the formation of bound states -- or molecules -- and support these predictions with dynamical simulations. We analytically determine the dissociation energy of bound states consisting of two oppositely polarized solitons and find good agreement with full numerical simulations. Collisions between bound states -- either with other bound states or with individual solitons -- produce intriguing dynamics. Notably, collisions between a pair of bound states exhibit a dipole-like behavior. We anticipate that such bound states, along with their rich collision dynamics, are within reach of current experimental capabilities.
