On arXiv: A direct dispersive signature of Pauli spin blockade

One of the key signatures of quantum mechanics is the Pauli principle, ensuring proper symmetry of the wavefunction under exchange of the particles. For fermions such as electrons or holes in semiconductor nanostructures, this is embodied…
