Energy thresholds for the existence of breather solutions and traveling waves on lattices
(2010)
We discuss the existence of breathers and of energy thresholds for their formation in DNLS lattices with linear and nonlinear impurities. In the case of linear impurities we present some new results concerning important ...

Lower and upper estimates on the excitation threshold for breathers in DNLS lattices
(2009)
We propose analytical lower and upper estimates on the excitation threshold for breathers (in the form of spatially localized and time periodic solutions) in discrete nonlinear Schrödinger (DNLS) lattices with power ...

Supersonic Kinks in Coulomb lattices
(Springer International Publishing, 2014)
There exist in nature examples of lattices of elements for which the interaction is repulsive, the elements are kept in place because different reasons, as border conditions, geometry (e.g., circular) and, certainly, the ...
