Spin polarization induced by decoherence in a tunneling one-dimensional Rashba model
S. Varela, M. Peralta, V. Mujica +2
Basic questions on the nature of spin polarization in two terminal systems and the way in which decoherence breaks Time-Reversal Symmetry (TRS) are analyzed. We exactly solve sever…
Response to Comment on: Tunneling in DNA with Spin Orbit coupling
Solmar Varela, Iskra Zambrano, Bertrand Berche +2
The comment by O. Entin-Wohlman, A. Aharony, and Y. Utsumi, on our paper S. Varela, I. Zambrano, B. Berche, V. Mujica, and E. Medina, Phys. Rev. B 101, 241410(R) (2020) makes a few…
Magnetic and geometric effects on the electronic transport of metallic nanotubes
Felipe Serafim, Fernando A. N. Santos, Jonas R. F. Lima +3
The investigation of curved low-dimensional systems is a topic of great research interest. Such investigations include two-dimensional systems with cylindrical symmetry. In this wo…
A Chirality-Based Quantum Leap
Clarice D. Aiello, Muneer Abbas, John M. Abendroth +41
Chiral degrees of freedom occur in matter and in electromagnetic fields and constitute an area of research that is experiencing renewed interest driven by recent observations of th…
Spin-orbit interaction and spin selectivity for tunneling electron transfer in DNA
Solmar Varela, Iskra Zambrano, Bertrand Berche +2
Electron transfer (ET) in biological molecules such as peptides and proteins consists of electrons moving between well defined localized states (donors to acceptors) through a tunn…
Spin current generation and control in carbon nanotubes by combining rotation and magnetic field
Márcio M. Cunha, Jonas R. F. Lima, Fernando Moraes +2
We study the quantum dynamics of ballistic electrons in rotating carbon nanotubes in the presence of a uniform magnetic field. When the field is parallel to the nanotube axis, the…
