Ferromagnetism and superconductivity in the one-dimensional multi-orbital Hubbard model
Year: 2007
Type: conference-paper
Abstract: Using the numerical diagonalization method, we investigate the ferromagnetism and the superconductivity in the multi-orbital Hubbard model in one-dimension. To examine the superconductivity, we calculate the critical exponent Kρ based on the Luttinger liquid theory and the anomalous flux quantization in the superconducting region. Analyzing the value of Kρ, we obtain the phase diagram on the U′ - J parameter plane including the superconducting phase and the fully polarized ferromagnetic phase.
