Interplay of strongly correlated electrons and localized Ising moments in one-dimension
Chisa Hotta
We study the ground state properties of the one-dimensional quarter-filled strongly correlated electronic chain coupled by to another chain of antiferromagnetic Ising moments.…
Non-local network-excitation in the Ising antiferromagnet on the anisotropic triangular lattice
Chisa Hotta, Tetsuhiro Kiyota, Nobuo Furukawa
We study the Ising antiferromagnet on the triangular lattice which are interacting along three different directions via two -bonds and one anisotropic -bond with .…
"Nonmagnetic" Dimer Mott insulator induced by the coupling of spin with quantum electric dipoles
Chisa Hotta
We present an effective dipolar-spin model based on the strong coupling analysis, which may explain the possible origin of the "spin liquid Mott insulator". The issue is related to…
Density-matrix renormalization study of the frustrated fermions on the triangular lattice
S. Nishimoto, C. Hotta
We show that the two-dimensional density-matrix renormalization analysis is useful to detect the symmetry breaking in the fermionic model on a triangular lattice. Under the cylindr…
