Mechanisms of localization in a finite harmonically confined optical superlattice
A. Katsaris, I. A. Englezos, C. Weitenberg +2
We investigate the impact of harmonic confinement in a finite optical superlattice and reveal the different mechanisms that can lead to the emergence of localized states. The optic…
Continuum Model of Isospectrally Patterned Lattices
Fotis K. Diakonos, P. Schmelcher
Isospectrally patterned lattices (IPL) have recently been shown to exhibit a rich band structure comprising both regimes of localized as well as extended states. The localized stat…
-Continuum limit of bipartite lattices -- The SSH model
Fotios K. Diakonos, P. Schmelcher
We present a continuous non-local model that faithfully replicates the rich topological and spectral features of the Su-Schrieffer-Heeger (SSH) model. Remarkably, our model shares…
Computational Study of the Spectral Behaviour of Different Isospectrally Patterned Lattices
Peter Schmelcher
We perform a computational spectral analysis of different isospectrally patterned lattices (IPL). Having been introduced very recently, the lattice Hamiltonian of IPL consist of co…
