Magnetic properties in the metallic magnets with large anisotropy
Y. Taguchi, J. Nasu, A. Koga +2
We study low temperature properties in the metallic magnets, considering the itinerant electron mediated ferromagnetism. Applying the Monte Carlo simulations to the extended double…
Quantum Phase Transitions in the Hubbard Model on Triangular Lattice
Takuya Yoshioka, Akihisa Koga, Norio Kawakami
We investigate the quantum phase transitions in the half-filled Hubbard model on the triangular lattice by means of the path-integral renormalization group (PIRG) method with a new…
Systematic Analysis of Frustration Effects in Anisotropic Checkerboard Lattice Hubbard Model
Takuya Yoshioka, Akihisa Koga, Norio Kawakami
We study the ground state properties of the geometrically frustrated Hubbard model on the anisotropic checkerboard lattice with nearest-neighbor hopping and next nearest-neighb…
Mott Transition in the Hubbard Model on Checkerboard Lattice
Takuya Yoshioka, Akihisa Koga, Norio Kawakami
We investigate the bandwidth-controlled Mott transition in the Hubbard model on the checkerboard lattice at half filling using the path-integral renormalization group (PIRG) method…
