Prof. Dr. Adrian Bachtold

Activities:

Mechanical resonators based on carbon nanotubes, graphene, and semiconductor monolayers are truly exceptional sensors of mass and force. We are taking advantage of these sensing capabilities to study physical phenomena in extreme regimes that have not been explored thus far, because conventional measurement methods lack sensitivity. We are addressing different directions with major scientific interests, including nuclear magnetic resonance (NMR) measurements on single nuclear spins, electron spin resonance (ESR) measurements on single molecules, the study of nano-superfluidity in helium-4 films adsorbed onto suspended nanotubes, and the study of the basic properties of semiconductor monolayers, such as MoS2 and WSe2. Our work is highly interdisciplinary with possible implications in quantum science, optomechanics, nanoscience, condensed matter, and low-temperature physics.

Position(s):
We are always interested in excellent candidates who want to pursue a PhD or a postdoc in our group. For details please contact Prof. Adrian Bachtold.
