Ground-state phase diagram of the Kitaev-Heisenberg model on a kagome lattice
Katsuhiro Morita, Masanori Kishimoto, Takami Tohyama
The Kitaev-Heisenberg model on the honeycomb lattice has been studied for the purpose of finding exotic states such as quantum spin liquid and topological orders. On the kagome lat…
Cluster-Based Haldane States in Spin-1/2 Cluster Chains
Takanori Sugimoto, Katsuhiro Morita, Takami Tohyama
The Haldane state is a typical quantum and topological state of matter, which exhibits an edge state corresponding to symmetry-protected topological order in a one-dimensional inte…
Ground state phase diagram of Kitaev-Heisenberg model on honeycomb-triangular lattice
Masanori Kishimoto, Katsuhiro Morita, Yukihiro Matsubayashi +3
The Kitaev-Heisenberg model defined on both honeycomb and triangular lattices has been studied intensively in recent years as a possible model to describe spin-orbital physics in i…
Magnetic phase diagrams and magnetization plateaus of the spin-1/2 antiferromagnetic Heisenberg model on square-kagome lattice with three nonequivalent exchange interactions
Katsuhiro Morita, Takami Tohyama
Magnetization plateaus in quantum spin systems emerges in two-dimensional frustrated systems such as kagome lattice. The spin-1/2 antiferromagnetic Heisenberg model on square-kagom…
