驱动Kitaev模型中的Floquet Majorana边模和非阿贝尔任意子

Floquet Majorana Edge Mode and Non-Abelian Anyons in a Driven Kitaev Model

Masahiro Sato, Yuki Sasaki, Takashi Oka

摘要:

本文从理论上研究了具有磁电交叉耦合的Kitaev蜂窝模型中激光驱动的非平衡态。我们表明,一个拓扑自旋液体与一个无间隙的手征边缘模式出现时,我们施加一个椭圆或圆偏振激光。这是弗洛凯拓扑绝缘体的强相关量子自旋版本。在拓扑阶段,边缘模式是由马约拉纳费米子和散装有间隙的非阿贝尔任意子激发。

英文摘要:

We theoretically study laser driven nonequilibrium states in the Kitaev honeycomb model with a magnetoelectric cross coupling. We show that a topological spin liquid with a gapless chiral edge mode emerges when we apply an elliptically or circularly polarized laser. This is a strongly correlated quantum spin version of the Floquet topological insulator. In the topological phase, the edge mode is made from Majorana fermions and the bulk has gapped non-Abelian anyon excitations.
