Phys. Rev. B 78, 073105 (2008) [4 pages]Interplay between particle-hole splitting and the Kondo effect in quantum dotsReceived 14 March 2008; revised 16 July 2008; published 18 August 2008 We discuss the influence of proximity effect on the quantum dot located between metallic and superconducting electrodes and consider its interplay with the Kondo state arising from the on-dot correlations. We show that upon increasing the hybridization to superconducting lead the Kondo resonance is gradually washed out. This behavior indirectly affects the subgap charge transport suppressing the zero-bias enhancement of the Andreev conductance. © 2008 The American Physical Society URL:
