Pseudogap and Kinetic Pairing Under Critical Differentiation of Electrons in Cuprate Superconductors
Masatoshi Imada, Shigeki Onoda
Superconducting mechanism of cuprates is discussed in the light of the proximity of the Mott insulator. The proximity accompanied by suppression of coherence takes place in an inho…

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…

Pseudogap and Superconducting Fluctuations in High-Tc Cuprates
Shigeki Onoda, Masatoshi Imada
We analyze pseudogap phenomena widely observed in the underdoped cuprates. We assume the existence of a strong d-wave pairing force competing with antiferromagnetic(AFM) fluctuatio…
