Travelling Wave Solution of the Fisher-Kolmogorov Equation with Non-Linear Diffusion ()

In this paper we study one-dimensional Fisher-Kolmogorov equation with density dependent non-linear diffusion. We choose the diffusion as a function of cell density such that it is high in highly cell ...

Making quantum vibrations nonlinear to enable phonon-phonon interactions

Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest ...

A Discrete-Time Formulation of Nonlinear Distributed-Parameter Port-Hamiltonian Systems

Abstract: This letter introduces a new framework of nonlinear, discrete-time, boundary control systems (BCSs) in the port-Hamiltonian form. The contribution is twofold. We start with a discrete-time ...
