We show that attractive two-dimensional (2D) spinor Bose–Einstein condensates with helicoidal spatially periodic spin–orbit coupling (SOC) support a rich variety of stable fundamental solitons and bound soliton complexes. Such states exist with c

Cherenkov radiation is generated from fast electrons and its optical analogue plays an important role in many nonlinear optical effects. Here, Skryabin et al. demonstrate backward-propagating photonic Cherenkov radiation generated from solitons in a

We observe linear and nonlinear light localization at the edges and in the corners of truncated moir\'e lattices created by the superposition of periodic mutually-twisted at Pythagorean angles square sublattices. Experimentally exciting corner linear

We show that attractive spinor Bose-Einstein condensates under the action of spin-orbit coupling (SOC) and Zeeman splitting form self-sustained stable two- and three-dimensional (2D and 3D) states in free space, even when SOC acts in a lower-dimensio

We report the experimental observation of nonlinear light localization and edge soliton formation at the edges of fs-laser written trimer waveguide arrays, where transition from non-topological to topological phases is controlled by the spacing betwe

Topological insulators (TI) have been the focal point of a remarkable level of experimental effort in the past two decades [1] . Their hallmark protected and scatter-free chiral edge states underpin the enormous applicative potential of topological s

In comparison with conventional lasers, whose stability may be affected by perturbations, such as defects and disorder, topological lasers may be remarkably stable when they lase in topologically protected edge states. In this work, we predict that c

We experimentally investigate nonlinear Kerr dynamics in higher-order photonic topological insulators. We excite nonlinear topological corner-modes that are robust against structural perturbations. Their localization demonstrates nontrivial nonmonoto

We introduce an exactly integrable nonlinear model describing the dynamics of spinor solitons in space-dependent matrix gauge potentials of rather general types. The model is shown to be gauge equivalent to the integrable system of vector nonlinear S
