Query: Long-range spin-coherence in a strongly-coupled all electronic
  dot-cavity system   We present a theoretical analysis of spin-coherent electronic transport
across a mesoscopic dot-cavity system. Such spin-coherent transport has been
recently demonstrated in an experiment with a dot-cavity hybrid implemented in
a high-mobility two-dimensional electron gas [C. R\"ossler et al., Phys. Rev.
Lett. 115, 166603 (2015)] and its spectroscopic signatures have been
interpreted in terms of a competition between Kondo-type dot-lead and
molecular-type dot-cavity singlet-formation. Our analysis brings forward all
the transport features observed in the experiments and supports the claim that
a spin-coherent molecular singlet forms across the full extent of the
dot-cavity device. Our model analysis includes: (i) a single-particle numerical
investigation of the two-dimensional geometry, its quantum-coral-type
eigenstates and associated spectroscopic transport features, (ii) the
derivation of an effective interacting model based on the observations of the
numerical and experimental studies, and (iii) the prediction of transport
characteristics through the device using a combination of a master-equation
approach on top of exact eigenstates of the dot-cavity system, and an
equation-of-motion analysis that includes Kondo physics. The latter provides
additional temperature scaling predictions for the many-body phase transition
between molecular- and Kondo-singlet formation and its associated transport
signatures.
