Fidelity and superconductivity in two-dimensional t-J models
Marcos Rigol, B. Sriram Shastry, Stephan Haas
We compute the ground-state fidelity and various correlations to gauge the competition between different orders in two-dimensional t-J-type models. Using exact numerical diagonaliz…

Kinetic Antiferromagnetism in the Triangular Lattice
Jan O Haerter, B Sriram Shastry
We show that the motion of a single hole in the infinite Hubbard model with frustrated hopping leads to weak metallic antiferromagnetism of kinetic origin. An intimate relation…
