      abstract     = {Magnetic adatoms on superconductors induce Yu-Shiba-Rusinov
                      (YSR) states, which are key to the design of low-dimensional
                      correlated systems and topological superconductivity.
                      Competing magnetic interactions and superconducting pairing
                      lead to a rich phase diagram. Using a scanning tunneling
                      microscope (STM), we position Fe atoms on
                      2⁢𝐻−NbSe$_2$to build a dimer with an odd-parity
                      ground state, i.e., a partially screened YSR channel with
                      the hybridized states spanning the Fermi level. This ground
                      state makes the dimer a promising precursor for a
                      topological YSR chain. By adding one atom at a time, we
                      track the formation of YSR bands. The lowest-energy band
                      crosses the Fermi level, and we find strong site-dependent
                      spectral variations especially at the chain's terminations.
                      We attribute these features to quantum spin effects and
                      ferromagnetic coupling influenced by the local chemical
                      environment.},
