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…
Nonlinear chiral refrigerators
David Sanchez, Rafael Sanchez, Rosa Lopez +1
We investigate a mesoscopic refrigerator based on chiral quantum Hall edge channels. We discuss a three-terminal cooling device in which charge transport occurs between a pair of v…
Nanowires: A route to efficient thermoelectric devices
F. Dominguez-Adame, M . Martin-Gonzalez, D. Sanchez +1
Miniaturization of electronic devices aims at manufacturing ever smaller products, from mesoscopic to nanoscopic sizes. This trend is challenging because the increased levels of di…
Nonlinear heat transport in ferromagnetic-quantum dot-superconducting systems
Sun-Yong Hwang, David Sanchez
We analyze the heat current traversing a quantum dot sandwiched between a ferromagnetic and a superconducting electrode. The heat flow generated in response to a voltage bias prese…
How to distinguish between interacting and noninteracting molecules in tunnel junctions
Miguel A. Sierra, David Sánchez, Alvar R. Garrigues +3
Recent experiments demonstrate a temperature control of the electric conduction through a ferrocene-based molecular junction. Here we examine the results in view of determining mea…
Heat current through an artificial Kondo impurity beyond linear response
Miguel A. Sierra, David Sanchez
We investigate the heat current of a strongly interacting quantum dot in the presence of a voltage bias in the Kondo regime. Using the slave- boson mean-field theory, we discuss th…
