Charge Oscillations Emerging after Application of an Intense Light Field to Superconductors on a Dimer Lattice
Kenji Yonemitsu
Motivated by recent experimental findings for an organic superconductor, charge oscillations that emerge after a strong pulse of an oscillating electric field is applied are studie…
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…
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…
One-Particle vs. Two-Particle Crossover in Weakly Coupled Hubbard Chains and Ladders: Perturbative Renormalization Group Approach
Jun-ichiro Kishine, Kenji Yonemitsu
Physical nature of dimensional crossovers in weakly coupled Hubbard chains and ladders has been discussed within the framework of the perturbative renormalization-group approach. T…
Spin Gap and Superconductivity in Weakly Coupled Ladders: Interladder One-particle vs. Two-particle Crossover
Jun-ichiro Kishine, Kenji Yonemitsu
Effects of the interladder one-particle hopping, , on the low-energy asymptotics of a weakly coupled Hubbard ladder system have been studied, based on the perturbative r…
