Detection of graphene’s divergent orbital diamagnetism at the Dirac point
We have measured for the first time the singular orbital magnetism of undoped graphene.
Microwave photoassisted dissipation and supercurrent of a phase-biased graphene-superconductor ring
We have probed a phase-biased graphene-superconductor ring via an rf resonator with a microwave pump.
Collapse of the Josephson Emission in a Carbon Nanotube Junction
We have measured a surprising collapse of the high frequency emission of a superconducting junction made with a carbon nanotube.
