Toward Kitaev's sixteenfold way in a honeycomb lattice model
Shang-Shun Zhang, Cristian D. Batista, Gábor B. Halász
Kitaev's sixteenfold way is a classification of exotic topological orders in which gauge theory is coupled to Majorana fermions of Chern number . The distinc…
Real space Berry curvature of itinerant electron systems with spin-orbit interaction
Shang-Shun Zhang, Hiroaki Ishizuka, Hao Zhang +2
By considering an extended double-exchange model with spin-orbit coupling (SOC), we derive a general form of the Berry phase that electrons pick up when moving around a closed…
Large- limit of the large- theory for the triangular antiferromagnet
Shang-Shun Zhang, E. A. Ghioldi, Yoshitomo Kamiya +3
Large- and large- theories (spin value and spinor component number ) are complementary, and sometimes conflicting, approaches to quantum magnetism. While large- spi…
Vison Crystals in an Extended Kitaev Model on the Honeycomb Lattice
Shang-Shun Zhang, Zhentao Wang, Gábor B. Halász +1
We introduce an extension of the Kitaev honeycomb model by including four-spin interactions that preserve the local gauge structure and hence the integrability of the original mode…
