Coupled wire construction of chiral spin liquids

Understand

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.
