Generalization of a localized-state formation mechanism in finite lattices with interaction nonlinearity
Huajie Song, Haitao Xu
We study how time-periodic, spatially localized states are born from the linear spectrum of a \emph{finite} lattice as the nonlinearity is switched on. In earlier work we treated t…

Analytical estimations of edge states and extended states in large finite-size lattices
Huajie Song, Haitao Xu
The bulk boundary correspondence, one of the most significant features of topological matter, theoretically connects the existence of edge modes at the boundary with topological in…
