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

It is now more than five years since the discovery of high-temperature supercon ductivity.
During this time an enormous amount of labor has gone toward inves tigating the cuprate …

We present a theoretical calculation, within a continuum electron-phonon-coupled model, of
the optical absorption due to polarons in polyacetylene [(CH) x]. Our results can be applied …

Conjugated polymers such as polyacetylene form a group of model semiconductors in which
the'one-dimensional'character of the polymer strongly modifies the behaviour of charges …

Polyacetylence,(CH) x is the simplest conjugated polymer. Prestine polyacetylence is a
good insulator, whereas its highly doped version exhibits metal-like electrical conductivity …

The ground and low-lying states of finite quantum-cell models with one state per site are
obtained exactly through a real-space basis of valence-bond (VB) diagrams that explicitly …

The time dependence of photoinduced optical absorption in the prototype one-dimensional
semiconductor, polyacetylene, is investigated with femtosecond resolution. It is found that …

Electrical charge flowing through organic semiconductors drives many of today's mobile
phone displays and television screens, suggesting an internally consistent model of charge …

Photoinduced dichroism caused by bleaching of the interband transition in trans-(CH) x was
observed in the picosecond time domain. The bleaching is induced instantaneously and …

The steady-state particle density n and the relaxation time τ of homogeneous density
fluctuations are calculated for one-dimensional systems in which particles move diffusively …
