Anomalous Flux Quantization in the Spin-Imbalanced Attractive Hubbard Ring

Kazuhiro Sano, Yoshiaki Ono

We investigate the one-dimensional Hubbard ring with attractive interaction in the presence of imbalanced spin populations by using the exact diagonalization method. The singlet pa…

Effect of magnetic field on the superconducting phase in the electron-doped metallic double-chain compound Pr $_{2}$ Ba $_{4}$ Cu $_{7}$ O $_{15 - δ}$

Taiji Chiba, Michiaki Matsukawa, Junki Tada +7

We report the magnetotransport and $d c$ magnetic susceptibility of the polycrystalline samples of Pr $_{2}$ Ba $_{4}$ Cu $_{7}$ O $_{15 - δ}$ , to examine the effect of magnetic field on the…
