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) …

Entanglement of edge modes in (very) strongly correlated topological insulators
Identifying topological phases for a strongly correlated theory remains a non-trivial task, as
defining order parameters, such as Berry phases, is not straightforward. Quantum …
