Heat flow enhancement in a nanoscale plasmonic junction induced by kondo resonances and electron-phonon coupling. Physica E: Low-Dimensional Systems and Nanostructures, 127 doi:10.1016/j.physe.2020.1145361386-94771873-1759https://doi.org/10.1016/j.physe.2020.114536https://hdl.handle.net/20.500.12428/3938Recently, we showed that plasmon-exciton coupling can increase entropy current through a bridge coupled to plasmonic metal nanoparticles. Here we show that electron-phonon coupling can also be used to control the entropy current in similar systems. Entropy current tends to decrease due to electron-phonon coupling and to exhibit a monotonous decrease upon temperature ramping. However, an anomaly affecting the current where it is enhanced by electron-phonon coupling is indicated at around 42 times the system’s Kondo temperature. We therefore report means to control heat flow by tuning the Kondo resonance through the electron-phonon coupling. We analyze the conditions that bring about these trends due to electron-phonon coupling by employing non-equilibrium Green’s function formulation addressing the entropy current and the derived heat flow.eninfo:eu-repo/semantics/openAccessHeat transportKondo temperatureNEGFPlasmonicElectron-phononArticle12710.1016/j.physe.2020.114536Q2WOS:0006051719000032-s2.0-85097719894
