Calculation of Penetration Depth and in -ETCu(NCS) under Pressure
Kazunori Tanaka, Hiroaki Ikeda, Kosaku Yamada
The pressure dependence of the inverse square of the magnetic penetration depth in -ETCu(NCS) was measured by Larkin, et al According to the paper, $λ^{- 2…
Interplay of crystal field structures with configuration to heavy fermions
Hiroaki Kusunose, Hiroaki Ikeda
We examine a relevance between characteristic of crystal field structures and heavily renormalized quasiparticle states in the -- Anderson lattice model. Using a sla…
Perturbation Analysis of Superconductivity in the Trellis-Lattice Hubbard Model
Sotaro Sasaki, Hiroaki Ikeda, Kosaku Yamada
We investigate pairing symmetry and transition temperature in the trellis-lattice Hubbard model. We solve the Éliashberg equation using the third-order perturbation theory with res…
Theory of Superconductivity in PuCoGa5
Kazunori Tanaka, Hiroaki Ikeda, Kosaku Yamada
Recently, superconductivity in PuCoGa5 was discovered. It has the same crystal structure as CeMIn5(M=Ir, Co, Rh). The electron correlation in PuCoGa5 is estimated to be weak compar…
Possible Pairing Symmetry of Superconductor Na_xCoO_2yH_2O
Yunori Nisikawa, Hiroaki Ikeda, Kosaku Yamada
To discuss a possibility that the superconductivities in Na_xCoO_2yH_2O are induced by the electron correlation, we investigate the possible pairing symmetry based on the single-ba…
