Flat band fine-tuning and its photonic applications
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 …

Tunable Aharonov-Bohm cages through imaginary couplings
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) …

Observation of inverse Anderson transitions in Aharonov-Bohm topolectrical circuits
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 …

Interplay and competition between disorder and flat band in an interacting Creutz ladder
We clarify the interplay and competition between disorder and flat band in the Creutz ladder
with interparticle interactions focusing on the system's dynamics. Without disorder, the …

Interaction-induced topological properties of two bosons in flat-band systems
In flat-band systems, destructive interference leads to the localization of noninteracting
particles and forbids their motion through the lattice. However, in the presence of …
