拓扑晶格模型中通过拓扑对称破缺的相变

Phase transitions in topological lattice models via topological symmetry breaking

F. J. Burnell, Steven H. Simon, J. K. Slingerland

摘要:

我们用拓扑序研究物质相之间的跃迁。通过研究这些过渡在完全可解的晶格模型,我们展示了如何普遍性类可能被确定和关键属性描述。作为一个熟悉的例子来具体说明我们的结果,我们详细描述了一个完全带隙的非手性二维$p$波超导体($p+ip$为赝自旋向上/ $p-ip$为赝自旋向下)之间的过渡到一个$s$波超导体,我们表明是在二维横向场伊辛普适类。

英文摘要:

We study transitions between phases of matter with topological order. By studying these transitions in exactly solvable lattice models we show how universality classes may be identified and critical properties described. As a familiar example to elucidate our results concretely, we describe in detail a transition between a fully gapped achiral 2D $p$-wave superconductor ($p+ip$ for pseudospin up/$p-ip$ for pseudospin down) to an $s$-wave superconductor which we show to be in the 2D transverse field Ising universality class.
