Unconventional Flatband Line States in Photonic Lieb Lattices
Shiqi Xia, Ajith Ramachandran, Shiqiang Xia +9
Flatband systems typically host "compact localized states"(CLS) due to destructive interference and macroscopic degeneracy of Bloch wave functions associated with a dispersionless…
Flat-band localization and self-collimation of light in photonic crystals
Nojoon Myoung, Hee Chul Park, Ajith Ramachandran +2
We investigate the optical properties of a photonic crystal composed of a quasi-one-dimensional flat-band lattice array through finite-difference time-domain simulations. The photo…
Fano Resonances in Flat Band Networks
Ajith Ramachandran, Carlo Danieli, Sergej Flach
Linear wave equations on Hamiltonian lattices with translational invariance are characterized by an eigenvalue band structure in reciprocal space. Flat band lattices have at least…
