Reaction-diffusion systems in natural sciences and new technology transfer
Journal of the Mechanical Behavior of Materials, 2012 Diffusion mechanisms in natural sciences and innovation management involve partial differential equations (PDEs). This is due to their spatio-temporal dimensions.

Frontiers of Bright CEP‐Stable Broadband Infrared Sources
Laser &Photonics Reviews, EarlyView.Bright CEP‐stable broadband infrared sources push the limits of ultrafast science by delivering exceptional brightness alongside few‐cycle durations and multi‐octave spectral coverage. This review highlights emerging architectures and nonlinear conversion strategies that scale power while preserving phase stability.

Laser &Photonics Reviews, EarlyView.Optical limiting in a nanomaterial‐polymer saturable absorber is harnessed as a functional intracavity degree of freedom, where pump‐controlled photothermal loss continuously reshapes the gain spectrum of rare‐earth ions, enabling non‐mechanical spectral engineering in an ultrafast fiber laser.

Soliton Solutions of the Negative Order Modified Korteweg – de Vries Equation
Известия Иркутского государственного университета: Серия "Математика"In this paper, we study the negative order modified Korteweg-de Vries (nmKdV) equation in the class of rapidly decreasing functions. In particular, we show that the inverse scattering transform technique can be applied to obtain the time dependence of ...

Q-soliton solution for two-dimensional q-Toda lattice
Қарағанды университетінің хабаршысы. Физика сериясы, 2019 The Toda lattice is a non-linear evolution equation describing an infinite system of masses on a line that interacts through an exponential force. The paper analyzes the construction of soliton solution for the q-Toda lattice in the two-dimensional case.

Analogue Hawking Radiation in Nonlinear LC Transmission Lines
Universe, 2021 Analogue systems are used to test Hawking radiation, which is hard to observe in actual black holes. One such system is the electrical transmission line, but it suffers the inevitable issue of excess heat that collapses the successfully generated ...

Laser &Photonics Reviews, EarlyView.Chip‐based frequency combs are usually pumped from telecom wavelengths, far from the visible. This work instead pumps close to the visible with a Ti:sapphire laser ‐ the source behind the original optical frequency combs and now becoming chip‐integrable‐ and lets silicon‐nitride waveguides convert it into efficient, octave‐spanning visible‐to‐infrared ...

Finite-density-induced motility and turbulence of chimera solitons
New Journal of Physics, 2022 We consider a one-dimensional oscillatory medium with a coupling through a diffusive linear field. In the limit of fast diffusion this setup reduces to the classical Kuramoto–Battogtokh model.
