论文摘要
由于希尔伯特空间的碎片化，也可能导致极地晶格气体的相互作用，即使在没有疾病的情况下也缺乏牙齿。我们表明，光学晶格中一维偶极气中的现场相互作用与通常被认为是$ 1/r^3 $依赖性的相反，获得了依赖横向限制和晶格深度的通用形式。 Due to the crucial role played by the nearest- and next-to-nearest neighbors, the Hilbert-space fragmentation and particle dynamics are very similar to that of a power-law model $1/r^{β_{\mathrm{eff}}<3}$, where $β_{\mathrm{eff}}$ is experimentally controllable by properly tailoring the transversal confinement.我们的结果与光学晶格中偶极气的实验具有直接的实验性相关性，并且表明，如果在强3D晶格中实现了质量动力学，或者通过强横向谐波限制，粒子动力学可能会大不相同。
Inter-site interactions in polar lattice gases may result, due to Hilbert-space fragmentation, in a lack of ergodicity even in absence of disorder. We show that the inter-site interaction in a one-dimensional dipolar gas in an optical lattice departs from the usually considered $1/r^3$ dependence, acquiring a universal form that depends on the transversal confinement and the lattice depth. Due to the crucial role played by the nearest- and next-to-nearest neighbors, the Hilbert-space fragmentation and particle dynamics are very similar to that of a power-law model $1/r^{β_{\mathrm{eff}}<3}$, where $β_{\mathrm{eff}}$ is experimentally controllable by properly tailoring the transversal confinement. Our results are of direct experimental relevance for experiments on dipolar gases in optical lattices, and show that the particle dynamics may be remarkably different if the quasi-1D lattice model is realized in a strong 3D lattice, or by means of a strong transversal harmonic confinement.
