In the present paper, we are interested in the effects of strong correlations. As electrons are confined in fewer dimensions, the

• contrast, for the short Rashba wires (with εm ≠ 0) the Kondo physics persists in both spin channels. In our present setup (Figure 7) the correlated quantum dot is between the metallic and superconducting reservoirs, therefore the Kondo effect is additionally affected by on-dot pairing. Its influence is
