Dynamic Effects on Colloidal Electric Interactions
"... Dynamic behaviors are abundant in field-responsive colloidal suspensions. Being beyond the usual point-dipole approximation, we develop a multiple image method of dipoles for two dynamic unequal colloidal dielectric spherical particles, which can be perfectly reduced to those for two static conducti ..."

Electron localization in an external electric field
, 2003
"... PACS 72.15.Rn [Localization effects] The impact of a weak electric field on the weak-localization corrections is studied within the framework of a nonlinear σ-model. Two scaling regimes are obtained. In one, the scaling is dominated by temperature; in the other, by the electric field. An explicit ex ..."

Non-linear effects and dephasing in disordered electron systems
, 2008
"... The calculation of the dephasing time in electron systems is presented. By means of the Keldysh formalism we discuss in a unifying way both weak localization and interaction effects in disordered systems. This allows us to show how dephasing arises both in the particle-particle channel (weak localiz ..."

Nonlinear Electroelastic Deformations
- Journal of Elasticity
"... Electro-sensitive (ES) elastomers form a class of smart materials whose mechanical properties can be changed rapidly by the appli-cation of an electric field. These materials have attracted consider-able interest recently because of their potential for providing rela-tively cheap and light replaceme ..."

, 2006
"... Abstract. We investigate the onset and maintenance of nonlinear soliton-like excitations in chains of atoms with Morse interactions at rather high densities, where the exponential repulsion dominates. First we discuss the atomic interactions and approximate the Morse potential by an effective Toda p ..."

that the nonlinear soliton-like excitations running on the chain interact with the electrons. They influence their motion in the presence of an external field creating dynamic bound states (“solectrons”, etc.). We show that these bound states can move very fast and create extra current. The soliton
Nonlinear Ionic Excitations, Dynamic Bound States, and Nonlin- ear Currents in a One-dimensional Plasma
, 2005
"... Key words One-dimensional plasmas, solitonic excitations, electron- soliton bound states, solectrons, soliton-driven currents. PACS 05.70.Ln, 05.70.Fh, 05.40Jc, 51.30+i, 52.25.Jm, 52.25.Kn, 52.35.Tc We study the role of nonlinear effects in a classical one-dimensional model of a conducting electron– ..."

NONLINEAR ELECTROMAGNETIC FORCES IN ASTROPHYSICS∗
, 2012
"... Electromagnetism becomes a nonlinear theory having (effective) photon– photon interactions due at least to electron–positron fluctuations in the vacuum. We discuss the consequences of the nonlinearity for the force felt by a charge probe particle, and compare the impact of Euler–Kockel QED effective ..."

Nonlinear Impurity in a lattice: Dispersion effects, Phys
- Rev. B
"... We examine the bound state͑s͒ associated with a single cubic nonlinear impurity, in a one-dimensional tight-binding lattice, where hopping to first-and second-nearest neighbors is allowed. The model is solved in a closed form vìa the use of the appropriate lattice Green function, and a phase diagra ..."
