Polarons in quasi-one-dimensional systems
We discuss the nature of polaron excitations in two models of current interest in the study of quasi-one-dimensional materials: the coupled electron-phonon and molecularcrystal models. Using for definiteness parameters appropriate to trans-(CH)„, we show that, although qualitatively very similar, the two polarons differ quantitatively in many respects. We then consider the very weakly bound pol...
متن کاملFerromagnetic correlations in quasi-one-dimensional conducting channels
We propose a model which explains the experimental observation of spontaneous spin polarization of conducting electrons in quasi-one-dimensional AlGaAs/GaAs channels [3,4]. We show that a ferromagnetic order is a generic property of a quasi-onedimensional conducting channel embedded in a Wigner crystal. We also discuss gate voltage, magnetic field and temperature dependences of the channel’s co...
متن کاملSolitonic States in Organic Conducting Polymers
In a typical solitonic distribution, the soliton density is distributed over the entire moleculeand the present work shows how its density can be decomposed into solitonic and antisolitoniccomponents. It is found that there exists a unique electron as soliton over the anionicnanoconductor, while there are many other solitons and antisolitons. The solitonic states are furtherdecomposed to the ca...

متن کاملEffects of the Gaussian energy dispersion on the statistics of polarons and bipolarons in conducting polymers.
We discuss the interpretation of usually broad oxidation peaks observed in electronically conducting polymers, in terms of the statistical distributions functions of polarons and bipolarons. The analysis is based on examining the chemical capacitance, that relates the change of concentration to a modification of the chemical potential of a given species, for different statistical models. We fir...
