Tetrahedral Spin Crystal to a Chiral Spin Liquid: Frustration-induced quantum melting

ORAL

Abstract

Motivated by the recent interest in interacting topological phases, we study the Haldane-Hubbard model which is shown to host a Mott insulating state with chiral tetrahedral magnetic texture. Frustration-induced melting of this spin crystal leads to a chiral spin liquid. We discuss the properties of these phases, and the Chern-Simons-Higgs theory of the intervening exotic quantum critical point.
