Tensor formulations for the modelling of discrete-time nonlinear and multidimensional systems.
The modelling of nonlinear and multidimensional systems from input and/or output measurements is considered. Tensor concepts are used to reformulate old results and develop several new ones. These results are verified through non-trivial computer simulations. A generalized tensor formulation for …

Nonlinear waves in systems with PT/CP - symmetric potentials
Arguably, one of the most elementary nonlinear lattice dynamical models is the discrete nonlinear Schrödinger (DNLS) equation [1]. Particularly, the discrete system and lattice solitons are the main objects of investigation in this work. In this thesis, we consider a chain of dimers, that is …

Quantum breathers in small networks: Dynamics, tunneling, correlations, and application to Josephson cells
… the excitation of quantum breathers in small nonlinear networks of two and three degrees of freedom, in order to study their properties. The invariance under permutation of two sites of these networks substitutes the translation invariance that is present in nonlinear lattices, where …
