Effects of bond-randomness and Dzyaloshinskii-Moriya interactions on the specific heat at low temperatures of a spherical kagomé cluster in {WV}
Mikio Motohashi, Kouki Inoue, Katsuhiro Morita +2
For the spin-1/2 spherical kagomé cluster, as well as for the 2D kagomé lattice, many low-energy singlet excitations have been expected to exist in the energy region below the spin…

Isothermal and adiabatic magnetization processes of the spin- Heisenberg model on an anisotropic triangular lattice
Katsuhiro Morita
In this study, we investigate the magnetic susceptibility, entropy, and isothermal magnetization curve of the spin-1/2 Heisenberg model on an anisotropic triangular lattice using t…

Magnetic phase diagrams of the spin- Heisenberg model on a kagome-strip chain: Emergence of a Haldane phase
Katsuhiro Morita, Shigetoshi Sota, Takami Tohyama
Frustrated one-dimensional quantum spin systems are known to exhibit a variety of quantum ground states due to the effects of quantum fluctuations and frustrations. In a spin-1/2 k…
