Infinite charge mobility in muscovite at 300K
(IOP, 2017)
Evidence is presented for infinite charge mobility in natural crystals of muscovite mica at room temperature. Muscovite has a basic layered structure containing a flat monatomic sheet of potassium sandwiched between ...

Pterobreathers in a model for a layered crystal with realistic potentials: Exact moving breathers in a moving frame
(American Physical Society, 2019-08-12)
In this article we perform a thorough analysis of breathers in a one-dimensional model for a layered silicate for which there exists fossil and experimental evidence of moving excitations along the close-packed lines of ...

Nonlinear waves in a chain of magnetically coupled pendula
(Acoustical Society of America, 2018)
A motivation for the study of reduced models like one-dimensional systems in Solid State Physics is the complexity of the full problem. In recent years our group has studied theoretically, numerically and experimentally ...

New classes of stable exact solutions for a nonlinear rotational DNA model
(Jagellonian University, 2010)
We consider a system of two coupled nonlinear partial differential equations for describing the rotational motions of bases in both polynucleotide chains of the DNA molecule. The model was proposed by L.V. Yakushevich and ...

Nonsymmetric moving breather collisions in the Peyrard-Bishop DNA model
(American Institute of Mathematical Sciences (AIMS), 2011)
We study nonsymmetric collisions of moving breathers (MBs) in the Peyrard-Bishop DNA model. In this paper we have considered the following types of nonsymmetric collisions: head-on collisions of two breathers traveling ...

Kinks supersónicos en redes repulsivas
(Real Sociedad Española de Física, 2013-07-07)
We have founds supersonics kinks in a model for the cation layer of mica muscovite. They are proposed as a posible explanation for the dark tracks in the mineral

Long range annealing of defects in germanium by low energy plasma ions
(Elsevier, 2015)
Ions arriving at a semiconductor surface with very low energy (2 - 8 eV) are interacting with defects deep inside the semiconductor. Several different defects were removed or modified in Sb-doped germanium, of which the ...

On the charge of quodons
(Institute for Metals Superplasticity Problems of Russian Academy of Sciences, 2016-03)
Muscovite mica is a mineral in which the tracks of charged swift particles, from radioactivity or cosmic rays, can be recorded and made visible by decoration with the mineral magnetite. Also, the tracks of quasi-one-dimensional ...

Kinks in Coulomb’s chains
(Universidad de Sevilla, 2012)
Chains of identical ions, for which the dominant interaction is the electrostatic repulsion, appear in layered silicates. The ions can move almost from site to site. The chains do not explode because the surrounding media ...

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 ...
