Optical vortex manipulation for topological quantum computation
Chengyun Hua, Gábor B. Halász, Eugene Dumitrescu +2
Proposed approaches to topological quantum computation based on Majorana bound states may enable new paths to fault-tolerant quantum computing. Several recent experiments have sugg…
Variational study of the Kitaev-Heisenberg-Gamma model
Shang-Shun Zhang, Gábor B. Halász, Wei Zhu +1
We compute the low-energy excitation spectrum and the dynamical spin structure factor of the Kitaev-Heisenberg-Gamma model through a variational approach based on the exact fractio…
Vacancy-induced low-energy density of states in the Kitaev spin liquid
Wen-Han Kao, Johannes Knolle, Gábor B. Halász +2
The Kitaev honeycomb model has attracted significant attention due to its exactly solvable spin-liquid ground state with fractionalized Majorana excitations and its possible materi…
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…
