Theory of Electron Nematic Order in LaOFeAs
Chen Fang, Hong Yao, Wei-Feng Tsai +2
We study a spin quantum Heisenberg model on the Fe lattice of the rare-earth oxypnictide superconductors. Using both large and large 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 square lattice with periodic boundary conditions and various degrees and patterns of inhom…

Myriad phases of the Checkerboard Hubbard Model
Hong Yao, Wei-Feng Tsai, Steven A. Kivelson
The zero temperature phase diagram of the checkerboard Hubbard model is obtained in the solvable limit in which it consists of weakly coupled square plaquettes. As a function of th…
