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…
Tilted Dirac cones and asymmetric conical diffraction in photonic Lieb-kagome lattices
Jean-Philippe Lang, Haissam Hanafi, Jörg Imbrock +1
The Lieb lattice and the kagome lattice, which are both well known for their Dirac cones and flat bands, can be continuously converted into each other by a shearing transformation.…
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…
