Josephson effect in quasi one-dimensional unconventional superconductors
Y. Asano, Y. Tanaka, Y. Tanuma +2
Josephson effect in junctions of quasi one-dimensional triangular lattice superconductors is discussed, where the theoretical model corresponds to organic superconductors (TMTSF)_2…
Crossover of superconducting properties and kinetic-energy gain in two-dimensional Hubbard model
Hisatoshi Yokoyama, Yukio Tanaka, Masao Ogata +1
Superconductivity in the Hubbard model on a square lattice near half filling is studied using an optimization (or correlated) variational Monte Carlo method. Second-order processes…
Josephson effect in d-wave superconductor junctions in a lattice model
S. Shirai, H. Tsuchiura, Y. Asano +4
Josephson current between two d-wave superconductors is calculated by using a lattice model. Here we consider two types of junctions, , the parallel junction and the mirror-t…
Nature of carriers in one-dimensional correlated electron systems
Hiroki Tsuchiura, Masao Ogata, Yukio Tanaka +1
Electron densities at the edge site in one-dimensional Hubbard model and t-J model are studied by using the Bethe ansatz solutions and exact diagonalization method. It is found tha…
Electronic states around a vortex core in high-Tc superconductors based on the t-J model
Hiroki Tsuchiura, Masao Ogata, Yukio Tanaka +1
Electronic states around vortex cores in high-Tc superconductors are studied using the two-dimensional t-J model in order to treat the d-wave superconductivity with short coherence…
