Emerging Device Applications From Strong Light–Matter Interactions in 2D Materials

Advanced Science, Volume 13, Issue 17, 23 March 2026.
Two‐dimensional semiconductors enable extremely compact optoelectronic devices such as solar cells, sensors, LEDs, and lasers. Their strong light–matter interactions allow efficient light emission, detection, and energy conversion. This review article discusses the recent progress in integrating these materials with optical cavities and nanostructures ...

Spin-wave growth via Shapiro resonances in a spinor Bose-Einstein condensate

Physical Review Research, 2021
We theoretically study the resonant phenomenon in a spin-1 Bose-Einstein condensate periodically driven by a quadratic Zeeman coupling. This phenomenon is closely related to the Shapiro steps in superconducting Josephson junctions, and the previous ...

Vortex Line Density in a Superfluid Turbulent Wake in the Zero Temperature Limit

Annalen der Physik, Volume 538, Issue 1, January 2026.
The quasiclassical conjecture for quantum turbulence in a pure superfluid straightforwardly leads to the definition of the superfluid Reynolds number, Res=ud/κ$Re_s=ud/\kappa$, and suggests that the effective quantum viscosity should be of the order of the circulation quantum κ$\kappa$.

Broadening of Spectral Lines for Decaying Trapped States of Photonic Meta‐Atoms

Electronics Letters, Volume 62, Issue 1, January/December 2026.
We discuss the phase‐matched capture‐and‐decay of dispersive waves by a photonic meta‐atom, enabled by higher‐order dispersive effects in a nonlinear waveguide. The emitted resonant modes exhibit a Lorentzian lineshape, with width determined by the lifetime of the decay process.

Self-Similarity Analysis of the Nonlinear Schrödinger Equation in the Madelung Form

Advances in Mathematical Physics, 2018
In the present study a particular case of Gross-Pitaevskii or nonlinear Schrödinger equation is rewritten to a form similar to a hydrodynamic Euler equation using the Madelung transformation.

Numerical Simulations of Coupled Solitary Waves With Spatially Modulated Non‐Linearity

Advances in Mathematical Physics, Volume 2026, Issue 1, 2026.
This study investigates the dynamics of two coupled solitary waves propagating in media characterised by spatially modulated non‐linearity and variable dispersion. By employing numerical simulations of a system of coupled non‐linear Schrödinger equations (NLSEs) with varying coefficients, we analyse how inhomogeneous physical properties influence ...

The stochastic Gross-Pitaevskii equation: II

, 2003
We provide a derivation of a more accurate version of the stochastic Gross-Pitaevskii equation, as introduced by Gardiner et al (2002 J. Phys. B: At. Mol. Opt. Phys. 35 1555).

Supercurrents and Tunneling in Massive Many‐Vortex Necklaces and Star‐Lattices

Annalen der Physik, Volume 537, Issue 12, December 2025.
It is numerically shown how massive many‐vortex systems, in a mixture of Bose–Einstein condensates, can host the bosonic tunneling of the infilling component in an almost‐periodic way when the vortices are organized in necklaces or star‐lattices. The purpose is to explore the conditions for the onset of Josephson supercurrents in rotating many‐vortex ...

Dynamical behaviour and solutions in the fractional Gross–Pitaevskii model

Mathematical and Computer Modelling of Dynamical Systems
The Gross–Pitaevskii equation is widely known for its applications in fields such as Bose–Einstein condensates and optical fibres. This study investigates the dynamical behaviour of various wave solutions to the M-fractional nonlinear Gross–Pitaevskii ...
