Vanishing Wilson ratio as the hallmark of quantum spin-liquid models
P. Prelovšek, K. Morita, T. Tohyama +1
We present numerical results for finite-temperature thermodynamic quantities, entropy , uniform susceptibility and the Wilson ratio , for several isotrop…
Magnetic orders induced by RKKY interaction in Tsai-type quasicrystalline approximant Au-Al-Gd
Haruka Miyazaki, Takanori Sugimoto, Katsuhiro Morita +1
Recent experimental study on Tsai-type quasicrystalline approximant Au-Al-Gd has revealed the presence of magnetic orders and phase transitions with changing the Au/Al concentratio…
Finite-temperature properties of the Kitaev-Heisenberg models on kagome and triangular lattices studied by improved finite-temperature Lanczos methods
Katsuhiro Morita, Takami Tohyama
Frustrated quantum spin systems such as the Heisenberg and Kitaev models on various lattices, have been known to exhibit various exotic properties not only at zero temperature but…
Magnetization plateau and supersolid phases in the spin-1/2 antiferromagnetic Heisenberg model on a tetragonally distorted fcc lattice
Katsuhiro Morita, Takami Tohyama
The Heisenberg model on a face center cubic (fcc) lattice is a typical three-dimensional frustrated spin system expected to have magnetization plateaus and supersolid phases. There…
