Caption: Picture of the prospective experimental setup in which Majorana particles could be made in a hybrid superconductor-nanowire material. In (a) the topological semiconductor bridges a gap between two parts of a superconductor. The letter phi represents an external magnetic field which can tailor conditions in the semiconductor. In (b) the immediate nanowire (gray rod) environment is shown. L is the size of the gap between the superconductor halves while L1 is the distance over which the underlying superconductivity will persist within the overlying semiconductor. (c) shows how the superconductor (SC)-semiconductor (SM) sandwich can be further tuned by a nearby electrical circuit.
