Variational Monte Carlo Study of a Spinless Fermion t-V Model on a Triangular Lattice: Formation of a Pinball Liquid
M. Miyazaki, C. Hotta, S. Miyahara +2
We analyze a model of spinless fermions on a triangular lattice at half-filling interacting via strong nearest-neighbor repulsive interactions, V, using the variational Monte Carlo…
Dimensional tuning of electronic states under strong and frustrated interactions
Chisa Hotta, Frank Pollmann
We study a model of strongly interacting spinless fermions on an anisotropic triangular lattice. At half-filling and the limit of strong repulsive nearest-neighbor interactions, th…
Universal temperature dependence of the magnetization of gapped spin chains
Yoshitaka Maeda, Chisa Hotta, Masaki Oshikawa
Temperature dependence of the magnetization of the Haldane spin chain at finite magnetic field is analyzed systematically. Quantum Monte Carlo data indicates a clear minimum of mag…
Strong coupling theory of the spinless charges on the triangular lattices: possibility of a new quantum liquid
Chisa Hotta, Nobuo Furukawa
We propose a new type of charge liquid state in the spinless fermion system on a triangular lattice under strong inter-site Coulomb interactions, . In the strong coupling limit…
New possibility of the ground state of quarter-filled one-dimensional strongly correlated electronic system interacting with localized spins
Chisa Hotta, Masao Ogata, Hidetoshi Fukuyama
We study numerically the ground state properties of the one-dimensional quarter-filled strongly correlated electronic system interacting antiferromagnetically with localized $S=1/2…
Comments on "Dimerization Induced by the RKKY Interaction"
Naokazu Shibata, Chisa Hotta
Recently, Xavier et al. claimed the existence of an insulating spin dimer state in the one-dimensional Kondo lattice model at quarter-filling amidst the paramagnetic metallic phase…
