Query: Erasing odd-parity states in semiconductor quantum dots coupled to
  superconductors   Quantum dots are gate-defined within InSb nanowires, in proximity to NbTiN
superconducting contacts. As the coupling between the dot and the
superconductor is increased, the odd-parity occupations become non-discernible
(erased) both above and below the induced superconducting gap. Above the gap,
conductance in the odd Coulomb valleys increases until the valleys are lifted.
Below the gap, Andreev bound states undergo quantum phase transitions to
singlet ground states at odd occupancy. We observe that the apparent erasure of
odd-parity regimes coincides at low-bias and at high-bias. This observation is
reproduced in numerical renormalization group simulations, and is explained
qualitatively by a competition between Kondo temperature and the induced
superconducting gap. In the erased odd-parity regime, the quantum dot exhibits
transport features similar to a finite-size Majorana nanowire, drawing
parallels between even-odd dot occupations and even-odd one-dimensional subband
occupations.
