Pseudospin-2 in photonic chiral borophene
Philip Menz, Haissam Hanafi, Daniel Leykam +2
Pseudospin is an angular momentum degree of freedom introduced in analogy to the real electron spin in the effective massless Dirac-like equation used to describe wave evolution at…
Noncontractible loop states from a partially flat band in a photonic borophene lattice
Philip Menz, Haissam Hanafi, Jörg Imbrock +1
Flat band systems are usually associated to compact localized states (CLSs) resulting from the macroscopic degeneracy of eigenstates at the flat band energy. In case of singular fl…
Localized dynamics arising from multiple flat bands in a decorated photonic Lieb lattice
Haissam Hanafi, Philip Menz, Allan McWilliam +2
Photonic lattices have emerged as a promising approach to localize light in space, for example, through topologically protected edge states and Aharonov-Bohm caging. They are of pa…
Localized states emerging from singular and nonsingular flat bands in a frustrated fractal-like photonic lattice
Haissam Hanafi, Philip Menz, Cornelia Denz
We report on singular and nonsingular flat bands in a Sierpinski fractal-like photonic lattice. We demonstrate that the the lowest two bands, being isolated and degenerate due to g…
