We consider a ${ \mathcal P }{ \mathcal T }$ -symmetric ladder-shaped optical array consisting of a chain of waveguides with gain coupled to a parallel chain of waveguides with loss. All waveguides have the focusing Kerr nonlinearity. The array suppo

We study the nonlinear dynamics of torsional meta-molecules—sub-wavelength resonators with strong coupling between electromagnetic excitation and rotational deformation—and show that such structures may undergo self-oscillations. We develop a sem

Interference of linear plane waves produces non-trivial phenomena in both classical and quantum wave systems. Here, the authors describe and observe anomalously large time delays and frequency shifts in the resonant inelastic scattering of a 1D wave

Optical bistability occurs when the effects of nonlinear behaviour of materials cause hysteresis in the transmission and reflection of a device. A possible mechanism for this is a strong dependence of the optical intensity on the index of refraction,

Recently, solitary waves characterized by a mutual locking of the fundamental and second harmonics in quadratically nonlinear media attracted a lot of attention [1]. The excitation of solitary waves, the evolution of unstable ones or numerical collis

We briefly review recent numerical and analytical results related to the study of the coexistence of nonlinear dynamics and effects of disorder, mostly for soliton bearing systems. In particular, we point out that disorder may give rise to a more int

Dynamics of a sine-Gordon kink and small-amplitude breather bound on an attractive localised inhomogeneity are studied. The rates of energy emission from the kink oscillating near the inhomogeneity and from a quiescent breather performing internal os
