Flat band fine-tuning and its photonic applications
Carlo Danieli, Alexei Andreanov, Daniel Leykam +1
Flat bands - single-particle energy bands - in tight-binding networks have attracted attention due to the presence of macroscopic degeneracies and their extreme sensitivity to pert…
Higher-order exceptional point and Landau-Zener Bloch oscillations in driven non-Hermitian photonic Lieb lattices
Shiqiang Xia, Carlo Danieli, Yingying Zhang +6
We propose a scheme to realize parity-time (PT) symmetric photonic Lieb lattices of ribbon shape and complex couplings, thereby demonstrating the higher-order exceptional point (EP…
Observation of quincunx-shaped and dipole-like flatband states in photonic rhombic lattices without band-touching
Shiqiang Xia, Carlo Danieli, Wenchao Yan +9
We demonstrate experimentally the existence of compact localized states (CLSs) in a quasi-one-dimensional photonic rhombic lattice in presence of two distinct refractive-index grad…
