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 ...

Moving breathers in a bent DNA model
(2002)
We study the properties of moving breathers in a bent DNA model with short range interaction, due to the stacking of the base pairs, and long range interaction, due to the finite dipole moment of the bonds within each ...

Influence of moving breathers on vacancies migration
(Elsevier, 2003)
A vacancy defect is described by a Frenkel-Kontorova model with a discommensuration. This vacancy can migrate when interacts with a moving breather. We establish that the width of the interaction potential must be larger ...

Nonlinear edge modes in a honeycomb electrical lattice near the Dirac points
(Elsevier, 2020-06)
We examine - both experimentally and numerically - a two-dimensional nonlinear driven electrical lattice with honeycomb structure. Drives are considered over a range of frequencies both outside (below and above) and ...

Discrete breathers and Anderson modes: two faces of the same phenomenon?
(Elsevier, 1999)
Time-periodic localized oscillations occur in a variety of contexts, in particular in weakly coupled anharmonic lattices and in disordered harmonic networks of oscillators, where they are known respectively as discrete ...

Discrete moving breather collisions in a Klein-Gordon chain of oscillators
(2008)
We study the collisions of moving breathers with the same frequency, traveling with opposite directions within a Klein–Gordon chain of oscillators. Two types of collisions have been analyzed: symmetric and non-symmetric, ...

Impulse-induced localized nonlinear modes in an electrical lattice
(IOP Publishing, 2019)
Intrinsic localized modes, also called discrete breathers (DBs), can exist under certain conditions in one-dimensional nonlinear electrical lattices driven by external periodic excitations (PEs). In this work, we have ...

Discrete breathers for understanding reconstructive mineral processes at low temperatures
(American Chemical Society, 2006)
Reconstructive transformations in layered silicates need a high temperature in order to be observed. However, very recently, some systems have been found where transformation can be studied at temperatures 600°C below the ...

Nonlinear edge modes in a honeycomb electrical lattice near the Dirac points
(Elsevier, 2020-09)
We examine - both experimentally and numerically - a two-dimensional nonlinear driven electrical lattice with honeycomb structure. Drives are considered over a range of frequencies both outside (below and above) and ...

Demonstration of the stability or instability of multibreathers at low coupling
(2003)
Whereas there exists a mathematical proof for one-site breathers stability, and an unpublished one for two-site breathers, the methods for determining the stability properties of multibreathers rely on numerical computation ...
