We construct, by a procedure involving a dimensional reduction from a Chern–Simons theory with borders, an effective theory for (1 + 1)-dimensional superconductor. That system can be in either an ordinary phase or a topological one, depending on the value of two phases, associated to complex order parameters.

从 D = 3 到 D = 2 维：关于拓扑顺序的注释

我们通过一个涉及从带有边界的 Chern-Simons 理论进行降维的程序，构建了一个有效的 (1 + 1) 维超导体理论。该系统可以处于普通相位或拓扑相位，具体取决于与复杂阶参数相关的两个相位的值。
