Elliptic string solutions on $$\mathbb {R}\times \hbox {S}^2$$ R×S2 and their pohlmeyer reduction
We study classical string solutions on $$\mathbb {R}\times \hbox {S}^2$$ R×S2 that correspond to elliptic solutions of the sine-Gordon equation. In this work, these solutions are systematically derived by inverting the Pohlmeyer reduction.

Acoustic emission from a dislocation kink accelerated by an external force
The emission of elastic waves from a dislocation kink accelerated by a constant external force is presented. The dynamics of the dislocation kink interacting with longitudinal acoustic waves is described by a sine-Gordon--d'Alembert system,

Quantum simulation of expanding space–time with tunnel-coupled condensates
We consider two weakly interacting quasi-1D condensates of cold bosonic atoms. It turns out that a time-dependent variation of the tunnel-coupling between those condensates is equivalent to the spatial expansion of a one-dimensional toy-Universe, with ...

On Transformations of the Rabelo Equations
We study four distinct second-order nonlinear equations of Rabelo which describe pseudospherical surfaces. By transforming these equations to the constant-characteristic form we relate them to some well-studied integrable equations.
