摘要：
The honeycomb K-Gamma model is known to have both deconfined spin liquid and confined phases. We study here a confinement transition between the Kitaev spin liquid and a dimerized phase in the limit of strong bond anisotropy. By partially projecting out Majorana states we are able to map the model onto a model of weakly coupled Ising chains in a transverse field. Within this mapping the ordered Ising phase corresponds to the condensation of Z(2) fluxes, or confinement. Our results may improve our understanding of the extensively studied spin liquid candidate material alpha-RuCl3, where K-Gamma interactions are dominant.
