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…
Anisotropy as a diagnostic test for distinct tensor network wavefunctions of integer and half-integer spin Kitaev quantum spin liquids
Hyun-Yong Lee, Takafumi Suzuki, Yong Baek Kim +1
Contrasting ground states of quantum magnets with the integer and half-integer spin moments are the manifestation of many-body quantum interference effects. In this work, we invest…
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 ($…
Frustration-Induced Supersolid Phases of Extended Bose-Hubbard Model in the Hard-Core Limit
Wei-Lin Tu, Huan-Kuang Wu, Takafumi Suzuki
We investigate exotic supersolid phases in the extended Bose-Hubbard model with infinite projected entangled-pair state, numerical exact diagonalization, and mean-field theory. We…
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…
