Strong Correlation Effect and In-gap State in the Doped Electron-Hole Two-Band Hubbard Model Based on the Dynamical Mean-Field Theory
Masashi Akiyama, Yusuke Inokuma, Yoshiaki Ono
We investigate the strong correlation effect in the spinless electron-hole two-band Hubbard model using the dynamical mean-field theory. At half filling, both the renormalization f…
Carrier Density Dependence of Superconducting Transition Temperature in Electron-doped Based on the First-principles Calculations
Riku Ikaida, Kazuhiro Sano, Yoshimi Masuda +2
Electron-doped strontium titanate , known to be one of the most dilute superconductors, is investigated on the basis of the first-principles calculations. When the ca…
Crystal structures and superconducting properties of metallic double-chain based cuprate Pr2Ba4Cu7O15-delta
Masahide Hagawa, Michiaki Matsukawa, Kota Niinuma +7
We demonstrated the lattice structures and the superconducting phases of metallic double-chain based cuprate Pr2Ba4Cu7O15-delta exhibiting higher Tc. After the oxygen heat treatmen…
Transition Temperature of Superconductivity in Sodium Tungsten Bronze -Theoretical Study Based on First-principles Calculations-
Kazuhiro Sano, Yoshihiro Nitta, Yoshiaki Ōno
Using first-principles calculations, we examine the transition temperature of superconductivity in sodium tungsten bronze ( NaWO, where is equal to or less…
Effect of pressure on magneto-transport properties in the superconducting and normal phases of the metallic double chain compound PrBaCuO
Masayoshi Kuwabara, Michiaki Matsukawa, Keisuke Sugawara +1
To examine the electronic phase diagram of superconducting CuO double chains, we report the effect of external pressure on the magneto-transport properties in superconducting and n…
Superconductivity in the CuO double chain of Pr_2Ba_4Cu_7O_15-delta on the basis of Tomonaga-Luttinger liquid theory
Kazuhiro Sano, Yoshiaki Ono, Yuh Yamada
Recently, Matsukawa et al. have discovered a new superconductor Pr_2Ba_4Cu_7O_15-delta in which metallic CuO double chains are responsible for the superconductivity. To investigate…
