Nonlinear compact localized modes in flux-dressed octagonal-diamond photonic lattice
M. G. Stojanovic, S. Gundogdu, D. Leykam +4
Tuning the values of artificial flux in the two-dimensional octagonal-diamond lattice drives topological phase transitions, including between singular and non-singular flatbands. W…
Nonlinear signatures of Floquet band topology
Aleksandra Maluckov, Ekaterina Smolina, Daniel Leykam +3
We study how the nonlinear propagation dynamics of bulk states may be used to distinguish topological phases of slowly-driven Floquet lattices. First, we show how instabilities of…
Gradient catastrophe of nonlinear photonic valley-Hall edge pulses
Daria A. Smirnova, Lev A. Smirnov, Ekaterina O. Smolina +2
We derive nonlinear wave equations describing the propagation of slowly-varying wavepackets formed by topological valley-Hall edge states. We show that edge pulses break up even in…
