Hierarchical Structures of Quantum Geometric Spectrum in Quasicrystals: A Renormalization-Group Study
Quantum metric in the Fibonacci chain scales as an inverse power of the spectral gap, with exponents from renormalization-group recursion, and the scaling marks criticality in the Aubry-André-Harper model.
