Query: Quantum Renormalization Group for Ground-State Fidelity   Ground-state fidelity (GSF) and quantum renormalization group theory (QRG)
have proven useful tools in the study of quantum critical systems. Here we lay
out a general, unified formalism of GSF and QRG; specifically, we propose a
method to calculate GSF through QRG, obviating the need for calculating or
approximating ground states. This method thus enhances characterization of
quantum criticality as well as scaling analysis of relevant properties with
system size. We illustrate the formalism in the one-dimensional Ising model in
a transverse field and the anisotropic spin-1/2 Heisenberg model.
