Professor of Physics
Gleb Finkelstein is an experimentalist interested in physics of quantum nanostructures, such as Josephson junctions and quantum dots made of carbon nanotubes, graphene, and topological materials. These objects reveal a variety of interesting electronic properties that may form a basis for future quantum devices.

Five years ago, my laboratory observed superconducting current induced in the regime of the quantum Hall effect [F. Amet et al., Science 352, p. 966], which was the first observation of this kind in any material system. Last year, we reported on the 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]. We are continuing to work on this direction and have prepared two preprints (not yet posted).
In parallel with this main direction, we have been exploring other aspects of graphene-based Josephson junctions. Last year, we published and extensive study of quantized "Shapiro steps" in the same material system [T. Larson et al., Nano Letters 16, 862, (2020)]. (Incidentally, the impact factor of Nano Letters is more than 10, higher than e.g. PRL.)
Two years ago, we reported on the first realization of multi-terminal Josephson junctions in a ballistic material [A. Draelos et al., Nano Letters 19, 1039 (2019)]. We have then reported on fractional Shapiro steps in this system [E. Arnault et al., Nano Lett. 21, 9668 (2021)]. A preprint on “Classical Realizations of Multiplet Supercurrents” is about to be submitted.
On the technical side, we finished setting up and have been actively using our new dilution refrigerator. This new cryostat reaches an ultra-low temperature of 10 mK and high magnetic fields of 12 Tesla.
