Band touching from real space topology in frustrated hopping models(Topological Aspects of Solid State Physics)
Leon Balents,Doron L. Bergman,Congjun Wu +2 more
- 20 Mar 2009
TL;DR: In this paper, the authors consider the case where at least one energy band, at the maximum or minimum of the spectrum, is dispersionless, and show that this band touching is related to states which exhibit non-trivial topology in real space.

Observation of a Localized Flat-Band State in a Photonic Lieb Lattice
Sebabrata Mukherjee,Alexander Spracklen,Debaditya Choudhury,Nathan Goldman,Nathan Goldman,Patrik Öhberg,Erika Andersson,Robert R. Thomson +7 more
TL;DR: The first experimental realization of a dispersionless state is demonstrated, in a photonic Lieb lattice formed by an array of optical waveguides, which opens an exciting door towards quantum simulation of flat-band models in a highly controllable environment.
Discrete optics in femtosecond-laser-written photonic structures
Alexander Szameit,Stefan Nolte +1 more
TL;DR: In this article, a novel technique was developed with which waveguides can be directly written into various optical bulk materials using femtosecond laser pulses, which allows for the realization of a variety of innovative concepts which are not feasible using other fabrication methods.

TL;DR: The first experimental demonstration of a new type of localized state in the continuum, namely, compacton-like linear states in flat-band lattices in photonic Lieb lattices, which exhibit three tight-binding bands.

TL;DR: A new type of edge state is found: one residing on the bearded edge that has never been predicted or observed in graphene, and can be classified as a Tamm-like state lacking any surface defect.
