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…

Path-Integral Renormalization Group Method for Numerical Study of Strongly Correlated Electron Systems
Masatoshi Imada, Tsuyoshi Kashima
A numerical algorithm for studying strongly correlated electron systems is proposed. The groundstate wavefunction is projected out after numerical renormalization procedure in the…
