论文摘要
我们在II型超导体中使用涡旋物质作为操场，以研究不同类型的疾病如何影响系统的长波长密度波动。我们发现，无论涡旋 - 涡流相互作用如何，对于弱和致密点缺陷的样品，系统呈现系统的隐性超均衡顺序，其特征是在增加系统大小时对密度波动的代数抑制。我们还透露，相反，对于平面缺陷的样品过度均匀性被抑制，因为密度波动具有增加系统尺寸的无限制趋势。尽管其中一些结果是从以前的作品中得知的，但本文提出了基本发现，即平面疾病抑制超均匀性的能力在增加结构的柔软度以增加了更稀释的系统方面。
We use vortex matter in type-II superconductors as a playground to study how different types of disorder affect the long wavelength density fluctuations of the system. We find that irrespective of the vortex-vortex interaction, in the case of samples with weak and dense point defects the system presents the hidden order of hyperuniformity characterized by an algebraic suppression of density fluctuations when increasing the system size. We also reveal that, on the contrary, for samples with planar defects hyperuniformity is suppressed since density fluctuations have a tendency to unboundedness on increasing the system size. Although some of these results were known from previous works, this paper makes the fundamental discovery that the ability of planar disorder to suppress hyperuniformity grows on increasing the softness of the structure for more diluted systems.
