    "abstract": "Motivated by the growing importance of fidelity in quantum critical\nphenomena, we establish a general relation between fidelity and structure\nfactor of the driving term in a Hamiltonian through a newly introduced concept:\nfidelity susceptibility. Our discovery, as shown by some examples, facilitates\nthe evaluation of fidelity in terms of susceptibility using well developed\ntechniques such as density matrix renormalization group for the ground state,\nor Monte Carlo simulations for the states in thermal equilibrium.",
