Vortex Light Bullets Guided by Disclination Defects

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
A new class of stable and thresholdless light bullets carrying vorticity, guided by the disclination defects introduced into Su–Schrieffer–Heeger‐like lattices with a focusing cubic nonlinearity, is reported. Different discrete rotational symmetry of the aperiodic lattice determines the allowed values of the topological charge of the vortex bullets ...

Third Harmonic Generation in Transparent Longitudinal Epsilon‐Near‐Zero Multilayers

open access: yesNanophotonics, Volume 15, Issue 14, 27 July 2026.
Transparent longitudinal epsilon‐near‐zero stacks enable field‐enhanced nonlinear light generation while preserving high near‐infrared pump transmission. Broadband third‐harmonic generation is experimentally observed demonstrating that TLENZ architectures can mitigate pump‐loss limitations and offer a promising platform for transparent nonlinear ...

Bilinearization and new multi-soliton solutions of mKdV hierarchy with time-dependent coefficients

open access: yesOpen Physics, 2016
In this paper, Hirota’s bilinear method is extended to a new modified Kortweg–de Vries (mKdV) hierarchy with time-dependent coefficients. To begin with, we give a bilinear form of the mKdV hierarchy. Based on the bilinear form, we then obtain one-soliton,

Bifurcation, Chaotic, Sensitivity Analysis, and Optical Soliton Profiles for the Spin Hirota–Maxwell–Bloch Equation in an Erbium-Doped Fiber

open access: yesAdvances in Mathematical Physics
In this work, the reduced spin Hirota–Maxwell–Bloch (rsHMB) equation is examined analytically. This model is useful for characterizing the propagation of femtosecond pulses in an erbium-doped fiber.

Fractional and Integrable Perspectives on a Variable-Coefficient Semi-Discrete NLS Equation: Analytical Method and Engineering Applications

open access: yesFractal and Fractional
The method of deriving fractional-order differential equations using Riesz fractional-order calculus is a new breakthrough, and it is possible to use the inverse scattering transform (IST) to solve the analytical solutions of the derived equations ...

Quantum backreaction effect in optical solitons

open access: yesNew Journal of Physics
Optical solitons classically are stationary solutions of the nonlinear Schrödinger equation. We perform a quantum field theoretic treatment by quantising a linearised fluctuation field around the classical soliton solution which can be seen as providing ...

Exact Soliton Solutions to the Variable-Coefficient Korteweg–de Vries System with Cubic–Quintic Nonlinearity

open access: yesMathematics
In this manuscript, we investigate the (2+1)-dimensional variable-coefficient Korteweg–de Vries (KdV) system with cubic–quintic nonlinearity. Based on different methods, we also obtain different solutions.
