Kitaev Meets Affleck-Kennedy-Lieb-Tasaki: Competing Quantum Disorder in Spin-3/2 Honeycomb Systems
Sogen Ikegami, Kiyu Fukui, Rico Pohle +1
We investigate an S=3/2 quantum spin model on a two-dimensional honeycomb lattice that continuously interpolates between two paradigmatic quantum disordered states with distinct en…

Topological transition induced by selective random defects on a honeycomb lattice
Sogen Ikegami, Kiyu Fukui, Shun Okumura +2
We investigate how the spectral and topological properties of electron systems evolve on a lattice that interpolates between the honeycomb and its 1/6-depleted structures through t…

Topological Majorana flat bands in the Kitaev model on a Bishamon-kikko lattice
Kiyu Fukui, Yukitoshi Motome
We unveil an interesting example of topological flat bands of Majorana fermions in quantum spin liquids. We study the Kitaev model on a periodically depleted honeycomb lattice, und…
