Spontaneous chirality selection and nonreciprocal spin wave in breathing-kagome antiferromagnets at zero field
Kazushi Aoyama, Hikaru Kawamura
It has been known that the spin-wave dispersion, which is usually symmetric in the momentum space with respect to , can be asymmetric in the presence of the Dzyaloshinsk…
Spin current as a probe of the -vortex topological transition in the classical Heisenberg antiferromagnet on the triangular lattice
K. Aoyama, H. Kawamura
We have theoretically investigated transport properties of the classical Heisenberg antiferromagnet on the triangular lattice in which a binding-unbinding topological transition of…
Magnetic phase diagram of the spin-1/2 antiferromagnetic zigzag ladder
T. Hikihara, T. Momoi, A. Furusaki +1
We study the one-dimensional spin-1/2 Heisenberg model with antiferromagnetic nearest-neighbor J_1 and next-nearest-neighbor J_2 exchange couplings in magnetic field h. With varyin…
Rate- and State-Dependent Friction Law and Statistical Properties of Earthquakes
Akio Ohmura, Hikaru Kawamura
In order to clarify how the statistical properties of earthquakes depend on the constitutive law characterizing the stick-slip dynamics, we make an extensive numerical simulation o…
Ground State Phase Diagrams of Frustrated Spin-S XXZ Chains: Chiral Ordered Phases
T. Hikihara, M. Kaburagi, H. Kawamura
The ground-state phase diagram of the frustrated spin-S XXZ chain with the competing nearest- and next-nearest-neighbor antiferromagnetic couplings is studied numerically by using…
