Ground state properties of determined from Hamiltonian and its extensions containing Kitaev and extended Heisenberg interactions
Tsuyoshi Okubo, Kazuya Shinjo, Youhei Yamaji +4
We investigate the ground state properties of based on numerical calculations of the recently proposed {\it ab initio} Hamiltonian represented by Kitaev and ex…

Finite-Temperature Signatures of Spin Liquids in Frustrated Hubbard Model
Takahiro Misawa, Youhei Yamaji
Finite-temperature properties of the frustrated Hubbard model are theoretically examined by using the recently proposed thermal pure quantum state, which is an unbiased numerical m…

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…
