Sine-Gordon Equation: From Discrete to Continuum
(Springer International Publishing, 2014)
In the present Chapter, we consider two prototypical Klein-Gordon models: the integrable sine- Gordon equation and the non-integrable φ4 model. We focus, in particular, on two of their prototypical solutions, namely the ...

Symmetry-breaking Effects for Polariton Condensates in Double-Well Potentials
(Springer Verlag, 2012)
We study the existence, stability, and dynamics of symmetric and anti-symmetric states of quasi-one-dimensional polariton condensates in double-well potentials, in the presence of nonresonant pumping and nonlinear damping. ...

Solitary Waves in the Nonlinear Dirac Equation at the Continuum Limit: Stability and Dynamics
(Nova, 2015)
In the present work, we give a comparative summary of different recent contributions to the theme of the linear stability and nonlinear dynamics of solitary waves in the nonlinear Dirac equation in the form of the Gross-Neveu ...

Nonlinearity and Topology
(Springer Nature, 2020)
The interplay of nonlinearity and topology results in many novel and emergent properties across a number of physical systems such as chiral magnets, nematic liquid crystals, Bose-Einstein condensates, photonics, high ...

Discrete breathers in Φ4 and related models
(Springer Nature, 2019)
In this Chapter, we touch upon the wide topic of discrete breather (DB) formation with a special emphasis on the prototypical system of interest, namely the 4 model. We start by introducing the model and discussing some ...

A Supersonic Crowdion in Mica Ultradiscrete Kinks with Energy between 40K Recoil and Transmission Sputtering
(Springer, 2015)
In this work we analyze in detail the behaviour and properties of the kinks found in an one dimensional model for the close packed rows of potassium ions in mica muscovite. The model includes realistic potentials obtained ...

Pileta Integral. Miradas desde el siglo XXI. Nuevas Tecnologías para una cueva excepcional
(Universitat d´Alacant / Universidad de Alicante, Instituto Universitario de Investigación en Arqueología y Patrimonio Histórico (INAPH), 2019)
La primera presentación, la más exhaustiva y completa del arte prehistórico de La Pileta se debe a Henri Breuil (Breuil et al., 1915). Este autor propone dos grandes fases, una paleolítica, distribuidas en tres ciclos ...

The origin of defects induced in ultra-pure germanium by Electron Beam Deposition
(Springer, 2015)
The creation of point defects in the crystal lattices of various semiconductors by subthreshold events has been reported on by a number of groups. These observations have been made in great detail using sensitive electrical ...

Nonlinear Beam Propagation in a Class of Complex Non-PT -Symmetric Potentials
(Springer Nature Singapure, 2018)
The subject of PT -symmetry and its areas of application have been blossoming over the past decade. Here, we consider a nonlinear Schrödinger model with a complex potential that can be tuned controllably away from being ...

Experimental observation of moving intrinsic localized modes in germanium
(Springer, 2015)
Deep level transient spectroscopy shows that defects created by alpha irradiation of germanium are annealed by low energy plasma ions up to a depth of several thousand lattice units. The plasma ions have energies of 2-8 ...
