  We investigate the spectral and transport properties of a double quantum dot
laterally attached to a topological superconducting nanowire, hosting the
Majorana zero-energy modes. Specifically, we consider a geometry, in which the
outer quantum dot is embedded between the external normal and superconducting
leads, forming a circuit. First, we derive analytical expressions for the bound
states in the case of an uncorrelated system and discuss their signatures in
the tunneling spectroscopy. Then, we explore the case of strongly correlated
quantum dots by performing the numerical renormalization group calculations,
focusing on the interplay and relationship between the leaking Majorana mode
and the Kondo states on both quantum dots. Finally, we discuss feasible means
to experimentally probe the in-gap quasiparticles by using the Andreev
spectroscopy based on the particle-to-hole scattering mechanism.
