Spin-polarized electron transmission in DNA-like systems
Miguel A. Sierra, David Sanchez, Rafael Gutierrez +3
The helical distribution of the electronic density in chiral molecules, such as DNA and bacteriorhodopsin, has been suggested to induce a spin-orbit coupling interaction that may l…
Fluctuation-driven Coulomb drag in interacting quantum dot systems
Miguel A. Sierra, David Sánchez, Antti-Pekka Jauho +1
Coulomb drag between nanoscale conductors is of both fundamental and practical interest. Here, we theoretically study drag in a double quantum-dot (QD) system consisting of a biase…
A thermally driven out-of-equilibrium two-impurity Kondo system
Miguel A. Sierra, Rosa Lopez, Jong Soo Lim
The archetypal two-impurity Kondo problem in a serially-coupled double quantum dot is investigated in the presence of a thermal bias . The slave-boson formulation is employed to…
Interactions and thermoelectric effects in a parallel-coupled double quantum dot
Miguel A. Sierra, M. Saiz-Bretin, F. Dominguez-Adame +1
We investigate the nonequilibrium transport properties of a double quantum dot system connected in parallel to two leads, including intradot electron-electron interaction. In the a…
