为了了解YBa2Cu3O7-x薄膜中的涡旋行为，研究了量子化涡旋的玻璃-液跃迁。我们系统地控制了YBa2Cu3O7-x薄膜中纳米包裹体的钉钉强度、空间分布和紊乱的形状。在这些无序系统中，我们观察到涡旋玻璃（VG）和玻色玻璃（BG）之间的交叉。钉钉强度的增加和各向同性无序的排序不会改变临界指数，而BG和VG之间的转换仅由钉钉中心的各向异性触发。(c) 2008年美国物理研究所。
The glass-liquid transitions of quantized vortices were studied to understand the vortex behavior in YBa2Cu3O7-x films. We systematically controlled the pinning strength, spatial distribution, and shape of disorders by engineering of nanoinclusions in YBa2Cu3O7-x films. In these disorder systems, we observed the crossover between the vortex glass (VG) and the Bose glass (BG). The increase in pinning strength and ordering of isotropic disorders do not change the critical exponents and the conversion between the BG and the VG is triggered only by the anisotropy of pinning centers.
