Generation and stability of discrete gap solitons

, 2003
We analyze stability and generation of discrete gap solitons in weakly coupled optical waveguides. We demonstrate how both stable and unstable solitons can be observed experimentally in the engineered binary waveguide arrays, and also reveal a connection

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Fermionic bright soliton in a boson-fermion mixture

, 2005
We use a time-dependent dynamical mean-field-hydrodynamic model to study the formation of fermionic bright solitons in a trapped degenerate Fermi gas mixed with a Bose-Einstein condensate in a quasi-one-dimensional cigar-shaped geometry.

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

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Partially incoherent gap solitons in Bose-Einstein condensates

, 2006
We construct families of incoherent matter-wave solitons in a repulsive degenerate Bose gas trapped in an optical lattice (OL), i.e., gap solitons, and investigate their stability at zero and finite temperature, using the Hartree-Fock-Bogoliubov ...

Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

Spontaneous symmetry breaking of gap solitons in double-well traps

, 2008
We introduce a two dimensional model for the Bose-Einstein condensate with both attractive and repulsive nonlinearities. We assume a combination of a double well potential in one direction, and an optical lattice along the perpendicular coordinate.
