Nonlocal thermoelectric effects and nonlocal Onsager relations in a three-terminal proximity-coupled superconductor-ferromagnet device.
We study thermal and charge transport in a three-terminal setup consisting of one superconducting and two ferromagnetic contacts. We predict that the simultaneous presence of spin filtering and of spin-dependent scattering phase shifts at each of the two interfaces will lead to very large nonlocal thermoelectric effects both in clean and in disordered systems. The symmetries of thermal and elec...

Solid-state energy conversion technologies such as thermoelectric refrigeration and power generation require materials with low thermal conductivity yet high electrical conductivity and Seebeck coefficiency. Although semiconductors are the best thermoelectric materials, they rarely have the such features. Nanostructures such as superlattices, quantum wires, and quantum dots provide novel method...
متن کاملThermoelectrics of Interacting Nanosystems - Exploiting Superselection Instead of Time-Reversal Symmetry
Thermoelectric transport is traditionally analyzed using relations imposed by time-reversal symmetry, ranging from Onsager’s results to fluctuation relations in counting statistics. In this paper, we show that a recently discovered duality relation for fermionic systems—deriving from the fundamental fermion-parity superselection principle of quantum many-particle systems—provides new insights i...

In recent years, semiconductor nanostructures have become the model systems of choice for investigation of electrical conduction on short length scales. Quantum transport is studied in a two dimensional electron gas because of the combination of a large Fermi wavelength and large mean free path. In the present work, a numerical method is implemented in order to contribute to the understanding ...
