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 ($…
Quantized ΔS=2 Excitation Spectra by Confinement in an S=1 Spin Chain
Takafumi Suzuki, Sei-ichiro Suga
We calculate the dynamical spin-structure factor of the Ising spin chain with negative single-ion anisotropy in magnetic fields using the infinite time-evolving-block-decimat…
Quantized excitation spectra by magnon confinement in quasi-one-dimensional S=1 spin systems
Takafumi Suzuki, Sei-ichiro Suga
We apply the infinite time-evolving-block-decimation algorithm to calculate the dynamical spin-structure factors of the quasi-one-dimensional (q1D) S=1 antiferromagnetic spin syste…
Effective model with strong Kitaev interactions for -
Takafumi Suzuki, Sei-ichiro Suga
We use an exact numerical diagonalization method to calculate the dynamical spin structure factors (DSFs) of three ab-initio models and one ab-initio-guided model for a honeycomb-l…
