Nanowire reconstruction under external magnetic fields
Eva M. Fernández, Silvia N. Santalla, José Enrique Alvarellos +1
We consider the different structures that a magnetic nanowire adsorbed on a surface may adopt under the influence of external magnetic or electric fields. First, we propose a theor…
Entanglement detachment in fermionic systems
Hernán Santos, José Enrique Alvarellos, Javier Rodríguez-Laguna
This article introduces and discusses the concept of entanglement detachment. Under some circumstances, enlarging a few couplings of a Hamiltonian can effectively detach a (possibl…
Engineering large end-to-end correlations in finite fermionic chains
Hernán Santos, José E. Alvarellos, Javier Rodríguez-Laguna
We explore deformations of finite chains of independent fermions which give rise to large correlations between their extremes. After a detailed study of the Su-Schrieffer-Heeger (S…
Resonant behavior and unpredictability in forced chaotic scattering
Alexandre R. Nieto, Jesús M. Seoane, J. E. Alvarellos +1
Chaotic scattering in open Hamiltonian systems is a topic of fundamental interest in physics, which has been mainly studied in the purely conservative case. However, the effect of…
Defect-enhanced Rashba spin-polarized currents in carbon nanotubes
Hernán Santos, Leonor Chico, J. E. Alvarellos +1
The production of spin-polarized currents in pristine carbon nanotubes with Rashba spin-orbit interaction has been shown to be very sensitive to the symmetry of the tubes and the g…
All-electrical production of spin-polarized currents in carbon nanotubes: Rashba spin-orbit interaction
Hernán Santos, A. Latgé, J. E. Alvarellos +1
We study the effect of the Rashba spin-orbit interaction in the quantum transport of carbon nanotubes with arbitrary chiralities. For certain spin directions, we find a strong spin…
