Large thermoelectric power and figure of merit in a ferromagnetic-quantum dot-superconducting device
Sun-Yong Hwang, Rosa Lopez, David Sanchez
We investigate the thermoelectric properties of a quantum dot coupled to ferromagnetic and superconducting electrodes. The combination of spin polarized tunneling at the ferromagne…
Time dependent heat flow in interacting quantum conductors
Guillem Rosello, Rosa Lopez, Jong Soo Lim
We derive the frequency-resolved heat current expression in the linear response regime for a setup comprised of reservoir, interacting central site, and tunneling barrier under the…
Quantum point contacts as heat engines
Sebastian Pilgram, David Sanchez, Rosa Lopez
The efficiency of macroscopic heat engines is restricted by the second law of thermodynamics. They can reach at most the efficiency of a Carnot engine. In contrast, heat currents i…
Thermoelectric effects in quantum Hall systems beyond linear response
Rosa Lopez, Sun-Yong Hwang, David Sanchez
We consider a quantum Hall system with an antidot acting as an energy dependent scatterer. In the purely charge case, we find deviations from the Wiedemann-Franz law that take plac…
Cross thermoelectric coupling in normal-superconductor quantum dots
Sun-Yong Hwang, Rosa Lopez, David Sanchez
We discuss the nonlinear current of an interacting quantum dot coupled to normal and superconducting reservoirs with applied voltage and temperature differences. Due to the particl…
Heat asymmetries in nanoscale conductors: The role of decoherence and inelasticity
Javier Arguello-Luengo, David Sanchez, Rosa Lopez
We investigate the heat flow between different terminals in an interacting coherent conductor when inelastic scattering is present. We illustrate our theory with a two-terminal qua…
