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…
Crystal field splitting, local anisotropy, and low energy excitations in the quantum magnet YbCl
G. Sala, M. B. Stone, Binod K. Rai +9
We study the correlated quantum magnet, YbCl, with neutron scattering, magnetic susceptibility, and heat capacity measurements. The crystal field Hamiltonian is determined thro…
Competing orders in pyrochlore magnets from a spin liquid perspective
Chunxiao Liu, Gábor B. Halász, Leon Balents
The pyrochlore materials have long been predicted to harbor a quantum spin liquid, an intrinsic long-range-entangled state supporting fractionalized excitations. Existing pyrochlor…
