Composite Polarons in Ferromagnetic Narrow-Band Metallic Manganese Oxides
Moving electrons accompanied by Jahn-Teller phonon and spin-wave clouds may form composite polarons in ferromagnetic narrow-band manganites. The ground-state and the finite-temperature properties of such composite polarons are studied in the present paper. By using the variational method, it is shown that the energy of the system at zero temperature decreases with the formation of the composite...
متن کاملPolarons in DNA.
Many experiments have been done to determine how far and how freely holes can move along the stack of base pairs in DNA. The results of these experiments are usually described in terms of a parameter beta under the assumption that it describes an exponential decay with distance. The reported values range from beta < 0.2/A to beta > 1. 4/A. For the larger values of beta, the transport can be acc...
متن کاملSuperconducting Polarons and Bipolarons
The seminal work by Bardeen, Cooper and Schrieffer (BCS) extended further by Eliashberg to the intermediate coupling regime solved one of the major scientific problems of Condensed Matter Physics in the last century. The BCS theory provides qualitative and in many cases quantitative descriptions of low-temperature superconducting metals and their alloys, and some novel high-temperature supercon...
متن کاملPolarons in carbon nanotubes.
We use ab initio total-energy calculations to predict the existence of polarons in semiconducting carbon nanotubes (CNTs). We find that the CNTs' band edge energies vary linearly and the elastic energy increases quadratically with both radial and with axial distortions, leading to the spontaneous formation of polarons. Using a continuum model parametrized by the ab initio calculations, we estim...
متن کاملPolarons with a twist
We consider a polaron model where molecular rotations are important. Here the usual hopping between neighboring sites is affected directly by the electron-phonon interaction via a twist-dependent hopping amplitude. This model may be of relevance for electronic transport in complex molecules and polymers with torsional degrees of freedom, such as DNA, as well as in molecular electronics experime...
