Strain-induced Landau levels of Majorana fermions in an anisotropically interacting Kitaev model on a honeycomb lattice
Takuto Yamada, Sei-ichiro Suga
The energy structure of an anisotropically interacting Kitaev model on a honeycomb lattice under triaxial strain is investigated. A numerical calculation shows that quantized state…
Ground-state phase diagram of anisotropically interacting Heisenberg- models on a honeycomb lattice
Takafumi Suzuki, Takuto Yamada, Sei-ichiro Suga
In this paper, we investigate the ground-state phase diagram of the Heisenberg- model on a honeycomb lattice by dimer series expansion and exact diagonalization. We focu…
Ground-state properties of the model on a honeycomb lattice
Takuto Yamada, Takafumi Suzuki, Sei-ichiro Suga
We investigate the ground-state properies of the model on a honeycomb lattice using series expansions and numerical exact diagonalizations, where the model includes Kitaev ($…
Clues and criteria for designing Kitaev spin liquid revealed by thermal and spin excitations of honeycomb iridates NaIrO
Youhei Yamaji, Takafumi Suzuki, Takuto Yamada +3
Contrary to the original expectation, NaIrO is not a Kitaev's quantum spin liquid (QSL) but shows a zig-zag-type antiferromagnetic order in experiments. Here we propose exp…
Dynamical properties of the honeycomb-lattice Iridates
Takafumi Suzuki, Takuto Yamada, Youhei Yamaji +1
We investigate the dynamical properties of . For five effective models proposed for , we numerically calculate dynamical structure factors (DSFs)…
