手性自旋液体的耦合线结构

Coupled wire construction of chiral spin liquids

Tobias Meng, Titus Neupert, Martin Greiter, Ronny Thomale

摘要:

我们发展了一种手性自旋液体的耦合线结构。起始点是Mott机制中的电子的单个线,它们受到塞曼场和Rashba自旋轨道耦合的影响。线之间的合适的自旋翻转耦合产生阿贝尔手性自旋液体状态,其支持体隙上方的自旋子激发和手性边缘状态。该方法推广到非阿贝尔手征自旋液体在水平k与parafermionic边缘状态。

英文摘要:

We develop a coupled wire construction of chiral spin liquids. The starting point are individual wires of electrons in the Mott regime that are subject to a Zeeman field and Rashba spin-orbit coupling. Suitable spin-flip couplings between the wires yield an Abelian chiral spin liquid state which supports spinon excitations above a bulk gap, and chiral edge states. The approach generalizes to non-Abelian chiral spin liquids at level k with parafermionic edge states.
