Majorana States in the Coulomb Blockade Regime – Signatures and Applications

Eran Sela

In this talk I will discuss recent experimental and theoretical advances combining one dimensional topological nanowires into small mesoscopic islands, pushing Majorana physics into the Coulomb blockade regime, and creating new quantum phases governed by correlations. I will elucidate that transport through such islands gives access to a rather unstudied type of quantum impurity physics, where the electrons in the leads combine with the Majorana fermions in the island to yield effective bosonic charge carriers. This gives rise to novel non-equilibrium transport behavior. Pushing these islands using a gate volatge into charge degeneracy points presents very interesting regimes allowing to probe strongly correlated Majorana fermions at short time scales and at high energy scales. In addition, creating arrays of such islands may form a highly convenient platform for topological quantum computing schemes based on the surface code. Here, electron transport can be used for quantum measurements and manipulation of the stored information in the Majorana qubits.
