论文摘要
可压缩的绝缘体相（称为玻色玻璃）的出现是相关玻璃流体中相互作用和障碍相互作用的特征。虽然在紧密结合模型中进行了广泛研究，但由于温度严格的影响，其观察值仍然难以捉摸。在这里，我们表明，可以通过在浅层准碘潜力中使用Lieb-Liniger玻色子来克服这个问题。在临界潜力和有限相互作用的范围之上发现了一个被超流体和莫特相包围的玻色玻璃。在有限温度下，我们表明莫特叶的融化是分形结构的特征，发现玻色玻璃与热波动的强大，直至可在量子气中访问的温度。我们的结果提出了有关这种浅层准碘潜力中玻色玻璃过渡的普遍性的问题。
The emergence of a compressible insulator phase, known as the Bose glass, is characteristic of the interplay of interactions and disorder in correlated Bose fluids. While widely studied in tight-binding models, its observation remains elusive owing to stringent temperature effects. Here we show that this issue may be overcome by using Lieb-Liniger bosons in shallow quasiperiodic potentials. A Bose glass, surrounded by superfluid and Mott phases, is found above a critical potential and for finite interactions. At finite temperature, we show that the melting of the Mott lobes is characteristic of a fractal structure and find that the Bose glass is robust against thermal fluctuations up to temperatures accessible in quantum gases. Our results raise questions about the universality of the Bose glass transition in such shallow quasiperiodic potentials.
