Novel properties in Josephson junctions involving the cos(kx)cos(ky)-pairing state in iron-pnictides

Wei-Feng Tsai, Dao-Xin Yao, B. Andrei Bernevig +1

We propose a trilayer $π$ -junction that takes advantage of the unconventional $s_{x^{2} y^{2}} = cos k_{x} cos k_{y}$ pairing symmetry which changes sign between electron and hole Fermi po…

Theory of Electron Nematic Order in LaOFeAs

Chen Fang, Hong Yao, Wei-Feng Tsai +2

We study a spin $S$ quantum Heisenberg model on the Fe lattice of the rare-earth oxypnictide superconductors. Using both large $S$ and large $N$ methods, we show that this model ex…

The Optimal Inhomogeneity for Superconductivity: Finite Size Studies

Wei-Feng Tsai, Hong Yao, Andreas Laeuchli +1

We report the results of exact diagonalization studies of Hubbard models on a $4 \times 4$ square lattice with periodic boundary conditions and various degrees and patterns of inhom…
