Non-Hermitian excitations in nonlinear topological lattice
Vlad Simonian, Daria A. Smirnova, Maxim A. Gorlach
Non-linear effects and non-Hermitian phenomena unveil additional intricate facets in topological matter physics. They can naturally intertwine to enable advanced functionalities in…
Identifying topology of leaky photonic lattices with machine learning
Ekaterina O. Smolina, Lev A. Smirnov, Daniel Leykam +2
We show how machine learning techniques can be applied for the classification of topological phases in leaky photonic lattices using limited measurement data. We propose an approac…
Water-Wave Vortices and Skyrmions
Daria A. Smirnova, Franco Nori, Konstantin Y. Bliokh
Topological wave structures -- phase vortices, skyrmions, merons, etc. -- are attracting enormous attention in a variety of quantum and classical wave fields. Surprisingly, these s…
Boosted second-harmonic generation in the LiNbO metasurface governed by high-Q guided resonances and bound states in the continuum
Ze Zheng, Lei Xu, Lujun Huang +4
To date, second-harmonic generation (SHG) at nanoscale has been concentrated on employing high-refractive-index nanostructures, owing to the strong field confinement at deep subwav…
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…
Probing band topology using modulational instability
Daniel Leykam, Ekaterina Smolina, Aleksandra Maluckov +2
We analyze the modulational instability of nonlinear Bloch waves in topological photonic lattices. In the initial phase of the instability development captured by the linear stabil…
