Aharonov-Bohm effect for an exciton in a finite width nano-ring
F. Palmero, J. Dorignac, J. C. Eilbeck +1
We study the Aharonov-Bohm effect for an exciton on a nano-ring using a 2D attractive fermionic Hubbard model. We extend previous results obtained for a 1D ring in which only azimu…
Classical and quantum nonlinear localized excitations in discrete systems
F. R. Romero, J. F. R. Archilla, F. Palmero +4
Discrete breathers, or intrinsic localized modes, are spatially localized, time--periodic, nonlinear excitations that can exist and propagate in systems of coupled dynamical units.…
Quantum breathers in an attractive fermionic Hubbard model
J. C. Eilbeck, F. Palmero
In one-dimensional translationally invariant anharmonic lattices, an extended Bloch state with two or more strongly correlated particles is usually called a quantum breather. Here…
Charge transport in poly(dG)-poly(dC) and poly(dA)-poly(dT) DNA polymers
D. Hennig, E. B. Starikov, J. F. R. Archilla +1
We investigate the charge transport in synthetic DNA polymers built up from single types of base pairs. In the context of a polaron-like model, for which an electronic tight-bindin…
Effect of base-pair inhomogeneities on charge transport along DNA mediated by twist and radial polarons
F. Palmero, J. F. R. Archilla, D. Hennig +1
Some recent results for a three--dimensional, semi--classical, tight--binding model for DNA show that there are two types of polarons, named radial and twist polarons, that can tra…
Nonlinear charge transport in DNA mediated by twist modes
F. Palmero, J. F. R. Archilla, D. Hennig +1
Recent works on localized charge transport along DNA, based on a three--dimensional, tight--binding model (Eur. Phys. J. B 30:211, 2002; Phys. D 180:256, 2003), suggest that charge…
