约瑟夫森结阵列中由其到π态的交叉引起的相变序列

Sequence of phase transitions induced in an array of Josephson junctions by their crossover to pi-state

S. E. Korshunov

摘要:

我们表明,由温度的降低引起的常规和π态之间的约瑟夫森结的过渡诱导在一个规则的二维阵列的这种结不只是一个单一的相变之间的两个阶段与不同的顺序,但两个,三个或四个相变的序列。相应的相图构造的情况下,二分(正方形或蜂窝状)和三角形晶格。

英文摘要:

We show that the transition of Josephson junctions between the conventional and pi states caused by the decrease in temperature induces in a regular two-dimensional array of such junctions not just a single phase transition between two phases with different ordering but a sequence of two, three or four phase transitions. The corresponding phase diagrams are constructed for the cases of bipartite (square or honeycomb) and triangular lattices.
