Higher-Order Flatband-Touching Points Mediate Unconventional Bulk-Boundary Correspondence
Limin Song, Jianqi Xiong, Liqin Tang +2
The bulk-boundary correspondence establishes a fundamental connection between bulk band topology and the emergence of boundary states, underpinning topological phenomena across ele…
Fractal hierarchy enables exponential scaling of topological boundary states
Limin Song, Zhichan Hu, Ziteng Wang +7
Exponential growth describes an extremely rapid process ubiquitous across mathematics and diverse physical, biological, and technological systems. Here, we introduce a class of fra…
Unveiling prethermalization and thermal processes through the simplest one-dimensional topological model
Guowen Yang, Jiale Wang, Yichuan Chen +5
Drawing on classical thermodynamic principles-such as the equipartition of energy and entropy maximization-extensive research has shown that the evolution of optical power in multi…
Bulk-hole correspondence and inner robust boundary modes in singular flatband lattices
Limin Song, Shenyi Gao, Shiqi Xia +5
Topological entities based on bulk-boundary correspondence are ubiquitous, from conventional to higher-order topological insulators, where the protected states are typically locali…
Multiple flat bands and localized states in photonic super-Kagome lattices
Limin Song, Shenyi Gao, Jina Ma +4
We demonstrate multiple flat bands and compact localized states (CLSs) in a photonic super-Kagome lattice (SKL) that exhibits coexistence of singular and nonsingular flat bands wit…
Observation of topologically distinct corner states in "bearded" photonic Kagome lattices
Limin Song, Domenico Bongiovanni, Zhichan Hu +6
Kagome lattices represent an archetype of intriguing physics, attracting a great deal of interest in different branches of natural sciences, recently in the context of topological…
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…
