Scaling of the fidelity susceptibility in a disordered quantum spin chain
N. Tobias Jacobson, Silvano Garnerone, Stephan Haas +1
The phase diagram of a quantum XY spin chain with Gaussian-distributed random anisotropies and transverse fields is investigated, with focus on the fidelity susceptibility, a recen…
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…
Fidelity approach to the disordered quantum XY model
Silvano Garnerone, N. Tobias Jacobson, Stephan Haas +1
We study the random XY spin chain in a transverse field by analyzing the susceptibility of the ground state fidelity, numerically evaluated through a standard mapping of the model…
