Interaction of moving discrete breathers with vacancies
J. Cuevas, J. F. R. Archilla, B. Sánchez-Rey +1
In this paper a Frenkel--Kontorova model with a nonlinear interaction potential is used to describe a vacancy defect in a crystal. According to recent numerical results [Cuevas et…
Closed model for granular compaction under weak tapping
J. J. Brey, A. Prados
A one dimensional lattice model is formulated to study tapping dynamics and the long time steady distribution in granular media. The dynamics conserves the number of particles in t…
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…
Energy funneling in a bent chain of Morse oscillators with long-range coupling
P. V. Larsen, P. L. Christiansen, O. Bang +2
A bent chain of coupled Morse oscillators with long-range dispersive interaction is considered. Moving localized excitations may be trapped in the bending region. Thus chain geomet…
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…
Universal restrictions to the conversion of heat into work derived from the analysis of the Nernst theorem as a uniform limit
Jose-Maria Martin-Olalla, Alfredo Rey de Luna
We revisit the relationship between the Nernst theorem and the Kelvin-Planck statement of the second law. We propose that the exchange of entropy uniformly vanishes as the temperat…
