Query: Kondo Correlation Induced Low-Field Magnetoresistance Anomalies in InSb
  Nanowire Josephson Quantum Dot Devices   We report the observation of sharp suppression of superconductivity-induced
zero-bias conductance peaks at low magnetic fields in InSb nanowire Josephson
quantum dot devices. With multiple gates, the quantum dot devices can be tuned
to the Kondo-superconductivity interplaying regime, in which Kondo-enhanced
superconductivity manifests as a zero-bias conductance peak. In weak magnetic
fields, the zero-bias conductance peak is found to exhibit an unusual negative
magnetoresistance when the Kondo temperature is comparable to the
superconductor gap. The observation could not be explained by magnetic field
induced '0-$\pi$' phase transition, topological phase transition, or other
known mechanisms, but may arise from correlation induced interference when
Cooper pairs cotunnel through the quantum dots.
