      abstract     = {Magnetotransport experiments on epitaxial GaAs/InAs
                      core/shell nanowires are performed in which the InAs shell
                      forms a tube-like conductive channel around the highly
                      resistive GaAs core. The core/shell nanowires are grown by
                      molecular beam epitaxy. It is found that the nanowire
                      conductance oscillates with the magnetic field oriented
                      parallel to its axis, with a period of the magnetic flux
                      quantum ϕ0=h/e. Related to that, it is shown that the
                      electronic transport is mediated by closed loop quantum
                      states encircling the wire axis rather than by electron
                      interference of partial waves. By means of a gate voltage
                      the conductance at zero magnetic field can be changed
                      between an oscillation minimum and maximum. The experimental
                      findings are supported by numerical calculations.},
