Frustration-induced quantum spin liquid behavior in the 1/2 random-bond Heisenberg antiferromagnet on the zigzag chain
Kazuki Uematsu, Toshiya Hikihara, Hikaru Kawamura
Recent studies have revealed that the randomness-induced quantum spin liquid (QSL)-like state is stabilized in certain frustrated quantum magnets in two and three dimensions. In or…
Monte Carlo studies of the spin-chirality decoupling in the three-dimensional Heisenberg spin glass
Takumi Ogawa, Kazuki Uematsu, Hikaru Kawamura
An extensive equilibrium Monte Carlo simulation is performed on the 3D isotropic Heisenberg SG model with the random nearest-neighbor Gaussian coupling, with particular interest in…
Monte Carlo study of the critical properties of noncollinear Heisenberg magnets: universality class
Yoshihiro Nagano, Kazuki Uematsu, Hikaru Kawamura
The critical properties of the antiferromagnetic Heisenberg model on the three-dimensional stacked-triangular lattice are studied by means of a large-scale Monte Carlo simulation i…
Nature of the randomness-induced quantum spin liquids in two dimensions
Hikaru Kawamura, Kazuki Uematsu
The nature of the randomness-induced quantum spin liquid state, the random-singlet state, is investigated in two dimensions (2D) by means of the exact-diagonalization and the Hams-…

Possibility of valence-fluctuation mediated superconductivity in Cd-doped CeIrIn probed by In-NQR
M. Yashima, N. Tagami, S. Taniguchi +8
We report on a pressure-induced evolution of exotic superconductivity and spin correlations in CeIr(InCd) by means of In-Nuclear-Quadrupole-Resonance (NQR) studie…
