Kaleidoscopes of Hofstadter butterflies and Aharonov-Bohm caging from 2^{n}-root topology in decorated square lattices
Square-root topology describes models whose topological properties can be revealed upon squaring the Hamiltonian, which produces their respective parent topological insulators. This concept has recently been generalized to 2^{n}-root topology, characterizing models where n squaring operations must b...
