Nonlinear dynamics of Aharonov-Bohm cages
Nonlinear dynamics of Aharonov-Bohm cages
The interplay of $\pi$-flux and lattice geometry can yield full localization of quantum dynamics in lattice systems, a striking interference phenomenon known as Aharonov-Bohm caging. At the level of the single-particle energy spectrum, this full-localization effect is attributed to the collapse of Bloch bands into a set of perfectly flat …
