过热超导颗粒平面阵列中择优跃迁诱导的动力学有序
Dynamical ordering induced by preferential transitions in Planar Arrays of Superheated Superconducting granules
摘要:
我们进行模拟的平面阵列的过热超导颗粒(PASS)下的外部磁场,分析所经历的系统时,外部磁场从零慢慢增加的过渡。我们观察到,对于高浓度,存在一个间隔的外部领域,没有过渡诱导。这种效应类似于在过热超导颗粒探测器的响应中识别的“热边界区”。我们解释这样的行为所产生的几何有序动态诱导系统中的优先网站由于抗磁相互作用的过渡。
英文摘要:
We perform simulations of planar arrays of superheated superconducting granules (PASS) under an external magnetic field, analyzing transitions undergone by the system when the external field is slowly increased from zero. We observe, for high concentrations, the existence of an interval of external fields for which no transitions are induced. This effect is analogous to a "hot border zone" identified in the response of Superheated Superconducting Granule detectors. We explain such behaviour as produced by a geometrical ordering dynamically induced in the system by transitions in preferential sites due to diamagnetic interactions.
