Competition between spin exchange and correlated hopping
Y. Saiga, M. Imada
The ground-state phase diagram is numerically studied for an electronic model consisting of the spin exchange term (J) and the correlated hopping term (t_3: the three-site term). T…
Operator Projection Theory for Electron Differentiation in Underdoped Cuprate Superconductors
Shigeki Onoda, Masatoshi Imada
Metals approaching the Mott insulator generate a new hierarchy in the electronic structure accompanied by a momentum dependent electron differentiation, beyond the Mott-Hubbard, Br…
Filling-Control Metal-Insulator Transition in the Hubbard Model Studied by the Operator Projection Method
Shigeki Onoda, Masatoshi Imada
Thermodynamic and dynamical properties of filling-control metal-insulator transition (MIT) in the Hubbard model are studied by the operator projection method, especially in two dim…
Origin of G-type Antiferromagnetism and Orbital-Spin Structures in
Masahito Mochizuki, Masatoshi Imada
The possibility of the distortion of octahedra is examined theoretically in order to understand the origin of the G-type antiferromagnetism (AFM(G)) and expe…
Path-Integral Renormalization Group Method for Numerical Study on Ground States of Strongly Correlated Electronic Systems
Tsuyoshi Kashima, Masatoshi Imada
A new efficient numerical algorithm for interacting fermion systems is proposed and examined in detail. The ground state is expressed approximately by a linear combination of numer…
Magnetic and Metal-Insulator Transitions through Bandwidth Control in Two-Dimensional Hubbard Models with Nearest and Next-Nearest Neighbor Transfers
Tsuyoshi Kashima, Masatoshi Imada
Numerical studies on Mott transitions caused by the control of the ratio between bandwidth and electron-electron interaction () are reported. By using the recently proposed path…
