Flat bands–single-particle energy bands–in tight-binding lattices, aka networks, have
attracted attention due to the presence of macroscopic degeneracies and their sensitivity to …

Aharonov-Bohm (AB) caging, a special flat-band localization mechanism, has spurred great
interest in different areas of physics. AB caging can be harnessed to explore the rich and …

Square-root topology is a recently emerged subfield describing a class of insulators and
superconductors whose topological nature is only revealed upon squaring their …

The Aharonov-Bohm (AB) cage enables localized confinement with nondiffractive
propagation for arbitrary excitation. In this study, we introduce an anti-parity-time (anti-PT) …

Transport inhibition via Anderson localization is ubiquitous in disordered periodic lattices.
However, in crystals displaying only flatbands, disorder can lift macroscopic band flattening …

It is well known that Anderson transition is a disorder-induced metal-insulator transition.
Contrary to this conventional wisdom, some investigations have shown that disorders could …

A different type of topological phase dubbed topological inverse Anderson insulators is
proposed, which is characterized by the disorder-induced extended bulk states from the flat …

We propose a quasi-one-dimensional non-Hermitian Creutz ladder with an entirely flat
spectrum by introducing alternating gain and loss components while maintaining inversion …

One-dimensional all-bands-flat lattices are networks with all bands being flat and highly
degenerate. They can always be diagonalized by a finite sequence of local unitary …

We show that four narrow zigzag dice lattice ribbons, which have the minimal widths among
their separate categories, constitute a unique collection of systems to study physics related …
