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 ...

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 ...

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 ...

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 ...
