Existence, stability and spatio-temporal dynamics of time-quasiperiodic solutions on a finite background in discrete nonlinear Schrödinger models
E. G. Charalampidis, G. James, J. Cuevas-Maraver +3
In the present work we explore the potential of models of the discrete nonlinear Schrödinger (DNLS) type to support spatially localized and temporally quasiperiodic solutions on to…
Scattering-induced splitting of solitons in the discrete NLS equation with saturable nonlinearity
J. F. Tsoplefack, F. Palmero, J. Cuevas-Maraver +2
We study systematically the scattering of solitons on localized impurities in the discrete nonlinear Schrödinger (DNLS) equation with a saturable nonlinearity. We show that, apart…
Backcasting COVID-19: A Physics-Informed Estimate for Early Case Incidence
G. A. Kevrekidis, Z. Rapti, Y. Drossinos +4
It is widely accepted that the number of reported cases during the first stages of the COVID-19 pandemic severely underestimates the number of actual cases. We leverage delay embed…
Breather stripes and radial breathers of the two-dimensional sine-Gordon equation
P. G. Kevrekidis, R. Carretero-González, J. Cuevas-Maraver +3
We revisit the problem of transverse instability of a 2D breather stripe of the sine-Gordon (sG) equation. A numerically computed Floquet spectrum of the stripe is compared to anal…
Kuznetsov-Ma breather-like solutions in the Salerno model
J. Sullivan, E. G. Charalampidis, J. Cuevas-Maraver +2
The Salerno model is a discrete variant of the celebrated nonlinear Schrödinger (NLS) equation interpolating between the discrete NLS (DNLS) equation and completely integrable Ablo…
A quantitative framework for exploring exit strategies from the COVID-19 lockdown
A. S. Fokas, J. Cuevas-Maraver, P. G. Kevrekidis
Following the highly restrictive measures adopted by many countries for combating the current pandemic, the number of individuals infected by SARS-CoV-2 and the associated number o…
