Generalized dispersion Kerr solitons
Published 2020We report a continuum of pulse-like soliton solutions to the generalized nonlinear Schr ̈odinger equation with both quadratic and quartic dispersion and a Kerr nonlinearity. We show that the well-known nonlinear Schr ...Open AccessArticle -
Stationary and Dynamical Properties of Pure-Quartic Solitons
Published 2019We numerically solve a generalized nonlinear Schrödinger equation and find a family of pure-quartic solitons, existing through a balance of positive Kerr nonlinearity and negative quartic dispersion. These solitons have ...Open AccessArticle -
Self-similar propagation of optical pulses in fibers with positive quartic dispersion
Published 2020We study the propagation of ultrashort pulses in optical fiber with gain and positive (or normal) quartic dispersion by self-similarity analysis of the modified nonlinear Schrödinger equation. We find an exact asymptotic ...Open AccessArticle -
Scenario modelling of biomass usage in the Australian electricity grid
Published 2022Responding to the global crises - Covid19 and climate change - governments around the world are formulating green recovery plans to stimulate economic growth, boost clean energy technologies and cut emissions. Potential ...Article -
Tourism, job vulnerability and income inequality during the COVID-19 pandemic
Published 2022The COVID-19 pandemic demonstrated the vulnerability of tourism workers, but no detailed job loss figures are available that links tourism vulnerability with income inequality. This study evaluates how reduced international ...Article
