Classification of Non-Hermitian Flat Bands
Chang-geun Oh, Jun-Won Rhim
Exact flat bands provide a versatile setting for correlated and topological phenomena, yet their properties are controlled not only by their dispersion but also by the structure of…
Topological flatband loop states in fractal-like photonic lattices
Limin Song, Yuqing Xie, Shiqi Xia +4
Noncontractible loop states (NLSs) are recently realized topological entity in flatband lattices, arising typically from band touching at a point where a flat band intersects one o…
Fractal-like photonic lattices and localized states arising from singular and nonsingular flatbands
Yuqing Xie, Limin Song, Wenchao Yan +5
We realize fractal-like photonic lattices using cw-laser-writing technique, thereby observe distinct compact localized states (CLSs) associated with different flatbands in the same…
Singular flat bands
Jun-Won Rhim, Bohm-Jung Yang
We review recent progresses in the study of flat band systems, especially focusing on the fundamental physics related to the singularity of the flat band's Bloch wave functions. We…
Realization of robust boundary modes and non-contractible loop states in photonic Kagome lattices
Jina Ma, Jun-Won Rhim, Liqin Tang +10
Corbino-geometry has well-known applications in physics, as in the design of graphene heterostructures for detecting fractional quantum Hall states or superconducting waveguides fo…
