Studies in Applied Mathematics, Volume 156, Issue 4, April 2026.ABSTRACT We study the nonlinear Schrödinger equation with a competing cubic–quintic power‐law nonlinearity on the waveguide domain Rx×TLy$\mathbb {R}_x \times \mathbb {T}_{L_y}$. This model is globally well‐posed and admits line solitary wave solutions, whose transverse (in‐)stability is numerically investigated.

Tạp chí Khoa học Đại học Đà LạtIn this study, we determine the interface position of a binary Bose-Einstein condensate mixture in the prewetting phase, confined by a hard wall, at absolute zero temperature. An approximate analytical result is obtained by employing the double-parabola

Two-dimensional Bose–Einstein condensate under pressure
New Journal of Physics, 2015 Evading the Mermin–Wagner–Hohenberg no-go theorem and revisiting with rigor the ideal Bose gas confined in a square box, we explore a discrete phase transition in two spatial dimensions.

Multiple front and pulse solutions in spatially periodic systems
Journal of the London Mathematical Society, Volume 113, Issue 4, April 2026.Abstract In this paper, we develop a comprehensive mathematical toolbox for the construction and spectral stability analysis of stationary multiple front and pulse solutions to general semilinear evolution problems on the real line with spatially periodic coefficients.

Merging van der Waals Materials and Optical Metasurfaces for Cavity Quantum Electrodynamics
Nanophotonics, Volume 15, Issue 5, 16 March 2026.Flat optical metasurfaces supporting quasi‐bound states in the continuum (qBIC) enable cavity‐like, high‐Q resonances in ultrathin nanostructures. This perspective explores the emergence of cavity quantum electrodynamics in qBIC metasurfaces, specifically those made from ultrathin van der Waals nanostructures, where cavities and emitters are seamlessly

European Physical Journal C: Particles and FieldsDuring the cosmic evolution process, as the temperature of a cosmological boson gas falls below a certain threshold, a Bose–Einstein condensation process can occur at various points throughout the cosmic history of the Universe.

Critical slowdown of non-equilibrium polaron dynamics
New Journal of Physics, 2019 We study the quantum dynamics of a single impurity following its sudden immersion into a Bose–Einstein condensate. The ensuing formation of the Bose polaron in this general setting can be seen as impurity decoherence driven by the condensate, which we ...

Soliton diffusion in a Bose-Einstein condensate: A signature of the analogue Hawking radiation
Physics Letters B, 2019 The analog Hawking radiation (HR) emanating from a sonic black hole horizon formed in a cigar-shaped Bose-Einstein condensate (BEC) at finite temperature is investigated. In particular, we study the effect of HR on a dark (topological) soliton.

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 ...

Coupling Enhancement and Symmetrization in Dissipative Optomechanical Systems
Annalen der Physik, Volume 538, Issue 3, March 2026.A practical circuit‐QED scheme with dual coherent laser driving and enhanced cross‐Kerr nonlinearity is presented to achieve ultrastrong optomechanical coupling in the few‐photon regime. A symmetric optomechanical dynamical framework is further established to enable a systematic classification of different coupling regimes.
