A zero-dimensional topologically nontrivial state in a superconducting quantum dot
Beilstein Journal of Nanotechnology, 2018 The classification of topological states of matter in terms of unitary symmetries and dimensionality predicts the existence of nontrivial topological states even in zero-dimensional systems, i.e., systems with a discrete energy spectrum.
