论文摘要
最近的发展突出了量子自旋模型实现限制的现象学的潜力,导致形成诸如介体等束缚状态。在这项工作中,我们表明Ising连锁店还提供了一个平台,以原始形式实现和探测粒子碰撞,其关键优势是,人们不仅可以监视碰撞事件的整个时空动力学,而且还可以监视渐近粒子的产生。我们研究了不同种类的介子和更复杂的介子状态之间的弹性和非弹性碰撞,这可以解释为量子染色体动力学中四夸克等外来颗粒的类似物。我们认为,我们的结果不仅适用于特定研究的旋转模型,而且可以在更一般的环境中容易扩展到晶格规定。正如所考虑的Ising连锁店在各种量子模拟器平台中承认了自然的实现,这是这项工作的关键含义,因此粒子碰撞因此在当前的实验范围内变得适合。具体而言,我们讨论了Rydberg Atoms系统中的潜在可行实施。
Recent developments have highlighted the potential of quantum spin models to realize the phenomenology of confinement leading to the formation of bound states such as mesons. In this work we show that Ising chains also provide a platform to realize and probe particle collisions in pristine form with the key advantage that one can not only monitor the asymptotic particle production, but also the whole spatiotemporal dynamics of the collision event. We study both elastic and inelastic collisions between different kinds of mesons and also more complex bound states of mesons, which one can interpret as an analog of exotic particles such as the tetraquark in quantum chromodynamics. We argue that our results not only apply to the specific studied spin model, but can be readily extended to lattice gauge theories in a more general context. As the considered Ising chains admit a natural realization in various quantum simulator platforms, it is a key implication of this work that particle collisions therefore become amenable within current experimental scope. Concretely, we discuss a potentially feasible implementation in systems of Rydberg atoms.
