Effect of breather existence on reconstructive transformations in mica muscovite
(2008)
Reconstructive transformations of layered silicates as mica muscovite take place at much lower temperatures than expected. A possible explanation is the existence of breathers within the potassium layer. Numerical analysis ...

Intersection of crisis loci in a driven nonlinearly damped oscillator
(Elsevier, 1995)
We report on a phenomenon observed in a driven nonlinearly damped oscillator when two control parameters, the frequency of the external excitation and the nonlinear damping coefficient, are varied simultaneously. An interior ...

Diffusion in a class of exactly solvable non-harmonic potentials. Intrinsic effects induced by non-linearities
(Elsevier, 1990)
This paper deals with the problem of a particle that diffuses in a potential with a reflecting barrier and has a point of stable equilibrium and a point of unstable equilibrium. Based on the exact solutions obtained earlier ...

Impulse-induced localized control of chaos in starlike networks
(American Physical Society, 2016)
Locally decreasing the impulse transmitted by periodic pulses is shown to be a reliable method of taming chaos in starlike networks of dissipative nonlinear oscillators, leading to both synchronous periodic states ...

Stability of non-time-reversible phonobreathers
(2011)
Non-time reversible phonobreathers are non-linear waves that can transport energy in coupled oscillator chains by means of a phase-torsion mechanism. In this paper, the stability properties of these structures have been ...

Localized oscillations in nonlinear hamiltonian Klein-Gordon lattices. Breathers and Anderson modes
(2002)
There are two different sources of localization in discrete lattices: • Anderson modes in disordered harmonic lattices [1] • Discrete breathers in homogeneous nonlinear lattices [2]

Discrete breathers collisions in nonlinear Schrödinger and Klein-Gordon lattices
(2008)
Collisions between moving localized modes (moving breathers) in non- integrable lattices present a rich outcome. In this paper, some features of the interaction of moving breathers in Discrete Nonlinear Schrödinger and ...

Moving breather collisions in Klein-Gordon chains of oscillators
(2009)
We investigate the collisions of moving breathers, with the same frequency, in three different Klein-Gordon chains of oscillators. The on-site potentials are: the asymmetric and soft Morse potential, the symmetric and soft ...

Moving discrete breathers in a Klein–Gordon chain with an impurity
(2002)
We analyse the influence of an impurity in the evolution of moving discrete breathers in a Klein–Gordon chain with non-weak nonlinearity. Three different types of behaviour can be observed when moving breathers interact ...

Breather trapping and breather transmission in a DNA model with an interface
(2006)
We study the dynamics of moving discrete breathers in an interfaced piecewise DNA molecule. This is a chain in which all the base pairs are identical and there exists a discontinuity in the orientation of the dipole moments ...
