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…

Fidelity in topological quantum phases of matter
Silvano Garnerone, Damian Abasto, Stephan Haas +1
Quantum phase transitions that take place between two distinct topological phases remain an unexplored area for the applicability of the fidelity approach. Here, we apply this meth…
