A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

Vector spatial and spatiotemporal laser solitons

Nanophotonics
Dissipative optical solitons, i.e. packets of radiation localized not due to the presence of optical inhomogeneities of the scheme or medium, but due to the balance of energy inflow and outflow in a nonlinear medium, deserve special attention for a ...

Quiescent Optical Solitons for the Perturbed Radhakrishnan–Kundu–Lakshmanan Equation with Nonlinear Chromatic Dispersion

Journal of Applied Science and Engineering
This paper recovers stationary optical solitons for the perturbed Radhakrishnan–Kundu–Lakshmanan equation with nonlinear chromatic dispersion. There are eight approaches that have been implemented to recover these solitons. A full spectrum of solitons is

Skyrmions in Scalar Fields of Non‐Hermitian Optical Microcavities: Spontaneous Formation, Nonlinear Control, and Optical Forces

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Skyrmion topology is shown to emerge spontaneously in scalar fields of driven‐dissipative optical microcavities, without externally imposed phase structure. In exciton‐polariton condensates, non‐Hermitian flow generates isolated Skyrmions and self‐organized Skyrmion lattices, while optical nonlinearities enable switching and reconfiguration of their ...

Fractional solitons with cubic dispersion [PDF]

APL Photonics
We report solitons in the presence of a cubic nonlinearity and piecewise cubic dispersion. This dispersion ensures that the associated group velocity of the light increases monotonically with frequency as required for the formation of optical solitons ...

Optical Soliton Neural Networks

, 2023
The chapter describes the realization of photonic integrated circuits based on photorefractive solitonic waveguides. In particular, it has been shown that X-junctions formed by soliton waveguides can learn information by switching their state. X junctions can perform both supervised and unsupervised learning.

Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

Advanced Functional Materials, Volume 36, Issue 79, 1 October 2026.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Quantum‐Mechanical Wave Functions in Singular Potentials: Linear and Nonlinear States

Advanced Physics Research, Volume 5, Issue 10, October 2026.
The attractive singular potential −1/r2$-1/r^2$ gives rise to the quantum collapse in the 3D linear Schroedinger equation. The article summarizes theoretical results demonstrating suppression of the collapse and creation of the missing ground state (GS) in a gas of bosonic particles, carrying an electric dipole moment, which are pulled to the central ...

Polarization‐Dependence of Nonlinear Optical Effects in Silicon: The Case of Ultrafast Processing

Advanced Physics Research, Volume 5, Issue 10, October 2026.
The dependence of the input polarization for the nonlinear optical propagation in silicon is investigated theoretically and experimentally. The perturbative regime is examined using pump‐probe shadowgraphy and nonlinear transmission, whereas the case of permanent laser‐induced modifications is addressed using a combination of Raman micro‐spectroscopy ...
