我们在实验上观察到了双离子链中单个极化激元和两个极化激元的动力学。通过驱动两个处于运动蓝边带（BSB）跃迁的囚禁离子，我们实现了反Jaynes-Cummings-Hubbard（JCH）模型。当单个极化激元存在于捕获离子链中时，极化激元在离子位点之间跳跃。另一方面，当在每个离子位置处存在单个极化激元时，由于反Jaynes-Cummings（JC）相互作用的非线性引起的极化激元-极化激元相互作用，极化激元的跳跃被抑制，从而实现了具有捕获离子的反JCH模型中极化激元跳跃的阻断。我们的工作是一个陷阱离子为基础的强相互作用极化激子系统的量子模拟器的发展迈出了一步。
We have experimentally observed the dynamics of a single polariton and two polaritons in a two-ion chain. By driving two trapped ions at a motional blue-sideband (BSB) transition, we realize the anti-Jaynes–Cummings–Hubbard (JCH) model. When a single polariton exists in a trapped-ion chain, the polariton hops between the ion sites. On the other hand, when there are single polaritons at each ion site, the hopping of the polaritons is suppressed because of the polariton–polariton interaction induced by the nonlinearity of the anti-Jaynes–Cummings (JC) interaction, thereby realizing the blockade of polariton hopping in the anti-JCH model with trapped ions. Our work is a step towards the development of a trapped-ion based quantum simulator for strongly interacting polaritonic systems.
