Electric polarization near vortices in the extended Kitaev model
Abstract We formulate a Majorana mean-field theory for the extended J KΓ Kitaev model in a magnetic Zeeman field of arbitrary direction, and apply it for studying spatially inhomogeneous states harboring vortices. This mean-field theory is exact in the pure Kitaev limit and captures the essential ph...
