... To explain the physics of conjugated polymers we take the simplest and most widely studied trans-PA. Although there exist many others, it is a useful example to use in order to clarify several ideas for the reader. Trans-PA is made up of unit cells each containing two carbon atoms and two hydrogen a ...

... In terms of the left-eigenvectors, the Rj (t)|V|Ri (t) inner product can be written as Lj (t)|Ri (t), with the inner product thus being the overlap of the left- and right-eigenvectors of the Hamiltonian. Because of (1.1) and (1.8), this inner product obeys Lj (t)|Ri (t) = Lj (0)|e−iHt eiHt |R ...

Quantum Transport in Finite Disordered Electron Systems
... The thesis has three parts. In the first Chapter of Part I the quantum transport methods have been used to extract the bulk resistivity of a three-dimensional conductor, modeled by an Anderson model on an nanoscale lattice (composed of several thousands of atoms), from the linear scaling of disorder- ...
