Fidelity Susceptibility Made Simple: A Unified Quantum Monte Carlo Approach
The fidelity susceptibility is a general purpose probe of phase transitions. With its origin in quantum information and in the differential geometry perspective of quantum states, the fidelity susceptibility can indicate the presence of a phase transition without prior knowledge of the local order p...
