Polychromatic Localized Waves with Complex Frequencies in Nonlinear Maxwell Equations with Material Dispersion

Tomas Dohnal, Maximilian Hanisch, Runan He

We study the existence of polychromatic solutions of cubically nonlinear Maxwell equations in the whole space and with dispersive media, i.e., with a time delayed polarization. Due…

Traveling modulating pulse solutions with small tails for a nonlinear wave equation in periodic media

Tomas Dohnal, Dmitry E. Pelinovsky, Guido Schneider

Traveling modulating pulse solutions consist of a small amplitude pulse-like envelope moving with a constant speed and modulating a harmonic carrier wave. Such solutions can be app…

Well-Posedness and Exponential Stability of Nonlinear Maxwell Equations for Dispersive Materials with Interface

Tomáš Dohnal, Mathias Ionescu-Tira, Marcus Waurick

In this paper we consider an abstract Cauchy problem for a Maxwell system modelling electromagnetic fields in the presence of an interface between optical media. The electric polar…

Justification of the Asymptotic Coupled Mode Approximation of Out-of-Plane Gap Solitons in Maxwell Equations

Tomáš Dohnal, Giulio Romani

In periodic media gap solitons with frequencies inside a spectral gap but close to a spectral band can be formally approximated by a slowly varying envelope ansatz. The ansatz is b…

Eigenvalue Bifurcation in Doubly Nonlinear Problems with an Application to Surface Plasmon Polaritons

Tomáš Dohnal, Giulio Romani

We consider a class of generally non-self-adjoint eigenvalue problems which are nonlinear in the solution as well as in the eigenvalue parameter ("doubly" nonlinear). We prove a bi…

Bifurcation of Gap Solitons in Coupled Mode Equations in Dimensions

Tomas Dohnal, Lisa Wahlers

We consider a system of first order coupled mode equations in describing the envelopes of wavepackets in nonlinear periodic media. Under the assumptions of a spectra…
