Berry phases and pairing symmetry in Holstein-Hubbard polaron systems
K. Yonemitsu, J. Zhong, H. -B. Schuttler
We study the tunneling dynamics of dopant-induced hole polarons which are self-localized by electron-phonon coupling in a two-dimensional antiferro- magnet. Our treatment is based…

Theory of Local Density of States of d-Wave Superconducting State Near the Surfaces of the t-J Model
Y. Tanuma, Y. Tanaka, M. Ogata +1
Spatial dependencies of the pair potential and the local density of states near the surfaces of -wave superconductors are studied theoretically. The calculation is…

Dimensional Crossovers in the Doped Ladder System: Spin Gap, Superconductivity and Interladder Coherent Band Motion
Jun-ichiro Kishine, Kenji Yonemitsu
Based on the perturbative renormalization group (PRG) approach, we have studied dimensional crossovers in Hubbard ladders coupled via weak interladder one-particle hopping, $t_{\pe…
