Quasi-1d quantum helimagnets: The fate of multipolar phases
S. Nishimoto, S. -L. Drechsler, R. Kuzian +2
Coupled frustrated spin-1/2 chains in high magnetic fields described within the ferro- antiferromagnetic J1-J2 Heisenberg model are studied by the DMRG, the hard core boson, and th…

Gapped state in three-leg Heisenberg tube
S. Nishimoto, M. Arikawa
We study the ground state of three-leg Heisenberg tube using the density-matrix renormalization group method. The dimerization order-parameter and spin-excitation gap are c…

Metal-insulator transition of the Kagome lattice fermions at 1/3 filling
Satoshi Nishimoto, Masaaki Nakamura, Aroon O'Brien +1
We discuss the metal-insulator transition of the spinless fermion model on the Kagomé lattice at 1/3-filling. The system is analyzed using exact diagonalization, the density-matrix…
