We provide an overview of recent experimental and theoretical developments in the area of
optical discrete solitons. By nature, discrete solitons represent self-trapped wavepackets in …

The increasing level of experimental control over atomic and optical systems gained in
recent years has paved the way for the exploration of new physical regimes in quantum …

We show that topologically protected defect states can exist in open (leaky or lossy) systems
even when these systems are topologically trivial in the closed limit. The states appear from …
