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 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…
Quantum Chernoff Bound metric for the XY model at finite temperature
Damian F. Abasto, N. Tobias Jacobson, Paolo Zanardi
We explore the finite temperature phase diagram of the anisotropic XY spin chain using the Quantum Chernoff Bound metric on thermal states. The analysis of the metric elements allo…
