Data-driven model reconstruction for nonlinear wave dynamics
Ekaterina Smolina, Lev Smirnov, Daniel Leykam +2
The use of machine learning to predict wave dynamics is a topic of growing interest, but commonly-used deep learning approaches suffer from a lack of interpretability of the traine…

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…

Parity anomaly laser
Daria A. Smirnova, Pramod Padmanabhan, Daniel Leykam
We propose a novel supersymmetry-inspired scheme for achieving robust single mode lasing in arrays of coupled microcavities, based on factorizing a given array Hamiltonian into its…
