标题： Kinetically-induced bound states in a frustrated Rydberg tweezer array

摘要： 理解粒子如何结合成复合物体是物理学中的一个普遍主题，从分子的形成到量子色动力学中的强子，以及超导体中电荷载体的配对。 束缚态的形成通常源于粒子之间的吸引力。 然而，结合也可以纯粹由于掺杂剂的运动而产生，这是由于动能挫折，这可能与莫尔材料中的非常规配对有关。 在这里，我们报告了使用玻色子$t$-$J$模型在受挫梯子和二维晶格中的里德伯原子阵列量子模拟器，首次直接观察到空穴和磁振子之间的动能诱导束缚态。 首先，我们展示了移动的一个空穴一个磁振子束缚态的形成。 然后，我们构建了三个粒子的一个空穴两个磁振子束缚态，并通过观察动能诱导的单重态关联揭示了其潜在的结合机制。 最后，我们研究了移动的掺杂剂如何在其磁性环境中进行结构化，显示一个空穴诱导$120^\circ$反铁磁序，而双电子掺杂剂则产生面内铁磁关联。 我们的结果展示了动能诱导结合的有力证据，为理解如莫尔超晶格中的超导体等相关量子材料中的新配对机制开辟了一条新途径。 显示英文摘要

摘要： Understanding how particles bind into composite objects is a ubiquitous theme in physics, from the formation of molecules to hadrons in quantum chromodynamics and the pairing of charge carriers in superconductors. The formation of bound states usually originates from attractive interactions between particles. However, the binding can also arise purely from the motion of dopants due to kinetic frustration, which is potentially related to unconventional pairing in moir\'e materials. Here, we report the first direct observation of kinetically-induced bound states between holes and magnons using a Rydberg atom array quantum simulator of the bosonic $t$-$J$ model in frustrated ladders and 2D lattices. First, we demonstrate the formation of mobile one-hole-one-magnon bound states. We then construct three-particle one-hole-two-magnon bound states and reveal the underlying binding mechanism by observing kinetically-induced singlet correlations. Finally, we investigate how mobile dopants structure their magnetic environment in a spin-balanced 2D triangular lattice, showing that a hole induces $120^\circ$ antiferromagnetic order, while a doublon dopant generates in-plane ferromagnetic correlations. Our results demonstrates compelling evidence of kinetically-induced binding, opening a new avenue to understand novel pairing mechanisms in correlated quantum materials like superconductors in moir\'e superlattices.
