Research Interests

My main research topic is the study of the coexistence of superconductivity and the quantum Hall effect. The highlights of this work include: the first observation of a superconducting current induced in the regime of the quantum Hall effect [F. Amet et al., Science 352, 966, 2016] and the first observation of the chiral Andreev edge states – neutral fermionic excitations formed at the interface of a superconductor and a quantum Hall system – predicted 20 years ago [L. Zhao et al., Nature Physics 16, 862, 2020]. The unique combination of the two of the most robust quantum states – quantum Hall effect and superconductivity – is interesting in its own right; it also promises future applications in quantum information science, e.g. for creation of topologically protected states and excitations. In parallel with this direction, we have been exploring multi-terminal Josephson junctions which we developed in ballistic graphene.  [A. Draelos et al., Nano Letters 19, 1039 (2019)].
