  • Title: The effect of Coulomb interactions on nonlinear thermovoltage and thermocurrent in quantum dots.
    Author: Zimbovskaya NA.
    Journal: J Chem Phys; 2015 Jun 28; 142(24):244310. PubMed ID: 26133431.
    Abstract:
    In the present work, we theoretically study the nonlinear regime of charge transport through a quantum dot coupled to the source and drain reservoirs. The investigation is carried out using a nonequilibrium Green's function formalism beyond the Hartree-Fock approximation. Employed approximations for the relevant Green's functions allow to trace a transition from Coulomb blockade regime to Kondo regime in the thermoelectric transport. Effects arising when electrons move in response to thermal gradient applied across the system are discussed, including experimentally observed thermovoltage zeros.
