Enhancing the nonlinear thermoelectric response of a correlated quantum dot in the Kondo regime by asymmetrical coupling to the leads
We study the low-temperature properties of the differential response of the current to a
temperature gradient at finite voltage in a single-level quantum dot including electron …

Width of the charge-transfer peak in the SU() impurity Anderson model and its relevance to nonequilibrium transport
We calculate the width 2 Δ CT and intensity of the charge-transfer peak (the one lying at the
on-site energy E d) in the impurity spectral density of states as a function of E d in the SU (N) …

Kondo physics of magnetic adatoms on metallic surfaces when the onset of the surface conduction density of states crosses the fermi level
J Fernández, P Roura-Bas - Physical Review B, 2019 - APS
We study the role of the onset of Shockley states D s belonging to (111) surfaces of Cu, Ag,
and Au in the Kondo effect when a magnetic impurity is deposited on them. When D s …
