Artificial flat band systems: from lattice models to experiments

D Leykam, A Andreanov, S Flach - Advances in Physics: X, 2018 - Taylor & Francis
Certain lattice wave systems in translationally invariant settings have one or more spectral
bands that are strictly flat or independent of momentum in the tight binding approximation …

Quantum transport in Rashba spin–orbit materials: a review

D Bercioux, P Lucignano - Reports on Progress in Physics, 2015 - iopscience.iop.org
In this review article we describe spin-dependent transport in materials with spin–orbit
interaction of Rashba type. We mainly focus on semiconductor heterostructures, however we …

Aharonov-Bohm caging and inverse Anderson transition in ultracold atoms

H Li, Z Dong, S Longhi, Q Liang, D Xie, B Yan - Physical Review Letters, 2022 - APS
Aharonov-Bohm (AB) caging, a special flat-band localization mechanism, has spurred great

Flat-band localization and interaction-induced delocalization of photons

JGC Martinez, CS Chiu, BM Smitham, AA Houck - Science Advances, 2023 - science.org
Lattices with dispersionless, or flat, energy bands have attracted substantial interest in part
due to the strong dependence of particle dynamics on interactions. Using superconducting …

Aharonov-Bohm cages, flat bands, and gap labeling in hyperbolic tilings

R Mosseri, R Vogeler, J Vidal - Physical Review B, 2022 - APS
Aharonov-Bohm caging is a localization mechanism stemming from the competition
between the geometry and the magnetic field. Originally described for a tight-binding model …

Interaction induced delocalization for two particles in a periodic potential

J Vidal, B Douçot, R Mosseri, P Butaud - Physical review letters, 2000 - APS
We consider two interacting particles evolving in a one-dimensional periodic structure
embedded in a magnetic field. We show that the strong localization induced by the magnetic …
