Phase-dependent microwave response of a graphene Josephson junction
Roy Haller, Gergő Fülöp, David Indolese +10
Gate-tunable Josephson junctions embedded in a microwave environment provide a promising platform to in-situ engineer and optimize novel superconducting quantum circuits. The key q…
Spin and valley degrees of freedom in a bilayer graphene quantum point contact: Zeeman splitting and interaction effects
Vanessa Gall, Rainer Kraft, Igor V. Gornyi +1
We present a study on the lifting of degeneracy of the size-quantized energy levels in an electrostatically defined quantum point contact in bilayer graphene by the application of…
Anomalous Cyclotron Motion in Graphene Superlattice Cavities
R. Kraft, M. -H. Liu, P. B. Selvasundaram +4
We consider graphene superlattice miniband fermions probed by electronic interferometry in magneto-transport experiments. By decoding the observed Fabry-Pérot interference patterns…
Andreev reflection in ballistic normal metal/graphene/superconductor junctions
P. Pandey, R. Kraft, R. Krupke +2
We report the study of ballistic transport in normal metal/graphene/superconductor junctions in edge-contact geometry. While in the normal state, we have observed Fabry-Pérot reson…
Electrostatic Superlattices on Scaled Graphene Lattices
Szu-Chao Chen, Rainer Kraft, Romain Danneau +2
A scalable tight-binding model is applied for large-scale quantum transport calculations in clean graphene subject to electrostatic superlattice potentials, including two types of…
Valley subband splitting in bilayer graphene quantum point contact
R. Kraft, I. V. Krainov, V. Gall +4
We report a study of one-dimensional subband splitting in a bilayer graphene quantum point contact in which quantized conductance in steps of is clearly defined down to…
Tailoring supercurrent confinement in graphene bilayer weak links
Rainer Kraft, Jens Mohrmann, Renjun Du +10
The Josephson effect is one of the most studied macroscopic quantum phenomena in condensed matter physics and has been an essential part of the quantum technologies development ove…
