Nonextensive E ects in Tight - Binding Systems with Long - Range Hopping
Consequences of long-range hopping in one-dimensional tight-binding models are studied. A hopping term proportional to 1=r ij is used, where rij denotes the distance between atoms i and j and determines the range of the interactions within the system. Calculations of the di usion of an electron along the lattice yield interesting e ects of nonextensivity. In particular, we nd that the mean squa...
متن کاملCritical Hamiltonians with long range hopping
Abstract. Critical states are studied by a real space RG in the problem with strong diagonal disorder and long range power law hopping. The RG flow of the distribution of coupling parameters is characterized by a family of non-trivial fix points. We consider the RG flow of the distribution of participation ratios of eigenstates. Scaling of participation ratios is sensitive to the nature of the ...
متن کاملCritical properties in long-range hopping Hamiltonians
Some properties of d-dimensional disordered models with long-range random hopping amplitudes are investigated numerically at criticality. We concentrate on the correlation dimension d2 (for d = 2) and the nearest level spacing distribution Pc(s) (for d = 3) in both the weak (b ≫ 1) and the strong (b ≪ 1) coupling regime, where the parameter b plays the role of the coupling constant of the model...
متن کاملLong-range charge hopping in DNA.
The fundamental mechanisms of charge migration in DNA are pertinent for current developments in molecular electronics and electrochemistry-based chip technology. The energetic control of hole (positive ion) multistep hopping transport in DNA proceeds via the guanine, the nucleobase with the lowest oxidation potential. Chemical yield data for the relative reactivity of the guanine cations and of...
