Ground-state properties for bilayer Kitaev model: dimer expansion study
Akihisa Koga, Hiroyuki Tomishige, Joji Nasu
We study ground state properties in the bilayer Kitaev model by means of the dimer expansion. The existence of parity symmetries in the system reduces the computational cost signif…

Ground-state and thermodynamic properties of an Kitaev model
Akihisa Koga, Hiroyuki Tomishige, Joji Nasu
We study ground-state and thermodynamic properties of an Kitaev model. We first clarify the existence of global parity symmetry in addition to the local symmetry on each plaq…
