Self-localized nonlinear excitations (solitons, polarons, and bipolarons) are fundamental
and inherent features of quasi-one-dimensional conducting polymers. Their signatures are …

This article reviews the static and dynamic properties of spontaneous superstructures
formed by electrons. Representations of such electronic crystals are charge density waves …

We trace the origin of θ-terms in nonlinear σ-models as a nonperturbative anomaly of current
algebras. The nonlinear σ-models emerge as a low energy limit of fermionic σ-models. The …

In this tutorial review, we cover the solid state physics approach to electronic and optical
properties of conducting polymers. We attempt to bring together languages and advantages …

The two-dimensional Gross-Neveu model is anticipated to undergo a crystalline phase
transition at high baryon charge densities. This conclusion is drawn from the mean-field …

We review recent advances in the theoretical modelling of π-conjugated polymers. Our
emphasis is on quasi-one-dimensional π-electron models that include both electron-phonon …

The magneto resistance (MR) of polyacetylene nanofibers is reviewed in this tutorial review.
Earlier MR results on film types of polyacetylene and other conducting polymers are …

We present a device model to describe polymer light‐emitting diodes (PLEDs) under bias
conditions for which strong electrical injection does not occur (ie, reverse, zero, and weak …

Most high-T c superconductors are spatially inhomogeneous. Usually, this heterogeneity
originates from the interplay of various types of electronic ordering. It affects various …

We study the coexistence of superconductivity (SC) and density-wave state and reconcile
various puzzling experimental data in organic superconductors (TMTSF) 2 PF 6 and …
