Straintronics and Twistronics in 2D Materials: Structural Control and Predictive Design

Small, EarlyView.
Strain and twist engineering in 2D materials is established as a programmable design parameter responsible for reconstructing lattices, tuning interlayer coupling, and developing new quantum functionalities. Through the integration of advanced fabrication techniques, multiscale characterization, computational modeling, and machine learning, this review

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.

Embedded Soliton Solutions: A Variational Study

Acta Physica Polonica A, 2008
We use a variational method to construct soliton solutions for systems characterized by opposing dispersion and competing nonlinearities at fundamental and second harmonics. We show that both ordinary and embedded solitons tend to gain energy when the second harmonic field becomes weaker than the first harmonic field.

A Minimalist Model for the Capture and Investigation of Solitary Waves in Gravity–Driven Liquid Films

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT A potential–based, first–integral formulation of the Navier–Stokes equations is used as a platform for modelling solitary waves in gravity‐driven film flow, giving rise to a nonlinear partial differential equation in complex form. Its subsequent modal decomposition—leading to an infinite set of ordinary differential equations (ODEs), followed ...

Soliton on Thin Vortex Filament

, 1990
"Showing that one of the equations found by Wadati Konno and Ichikawa is equivalent to the equation of motion of a thin vortex filament, we investigate solitons on the vortex filament. N vortex soliton solution is given in terms of the inverse scattering

Soliton-Propagation for Off-phase Pumping of Resoant frequency

, 2023
Soliton Fission of a second order soliton is slowed down by pumping the system with a single pulse, which is off-phase to the initial soliton. (Time-Domain and Frequency-Domain representation)

Dampened Diurnal Cycles of Hot‐Wet Extremes in Urban Areas Contrast With Thermally Driven Daytime Stress in Rural Landscapes of Beijing‐Tianjin‐Hebei Region

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Hot‐wet extremes (HWEs) are intensifying in the Beijing–Tianjin–Hebei region, but their fine‐scale diurnal urban–rural contrasts remain unclear. Using summer observations from 1,962 automatic weather stations during 2016–2024, we identify threshold‐exceeding HWE days and show that urban areas experience more compound day–night and independent ...

Complex and Real Optical Soliton Properties of the Paraxial Non-linear Schrödinger Equation in Kerr Media With M-Fractional

Frontiers in Physics, 2019
In this paper, we use the modified exponential function method in terms of Kf(x) instead of ef(x)and the extended sinh-Gordon method to find some new family solution of the M-fractional paraxial non-linear Schrödinger equation. The novel complex and real
