Vuik, A. (author), Nijholt, B. (author), Akhmerov, A.R. (author), Wimmer, M.T. (author)Andreev bound states in hybrid superconductor-semiconductor devices can have near-zero energy in the topologically trivial regime as long as the confinement potential is sufficiently smooth. These quasi-Majorana states show zero-bias conductance features in a topologically trivial phase, mimicking spatially separated topological Majorana...journal article 2019

Rosdahl, T.O. (author), Vuik, A. (author), Kjaergaard, M. (author), Akhmerov, A.R. (author)The proximity effect in hybrid superconductor-semiconductor structures, crucial for realizing Majorana edge modes, is complicated to control due to its dependence on many unknown microscopic parameters. In addition, defects can spoil the induced superconductivity locally in the proximitized system, which complicates measuring global...journal article 2018

Vuik, A. (author), Eeltink, D. (author), Akhmerov, A.R. (author), Wimmer, M.T. (author)One of the promising platforms for creating Majorana bound states is a hybrid nanostructure consisting of a semiconducting nanowire covered by a superconductor.Weanalyze the previously disregarded role of electrostatic interaction in these devices. Our main result is that Coulomb interaction causes the chemical potential to respond to an applied...journal article 2016
