Quantum NanoElectronics and NanoMechanics

Prof. Dr. Adrian Bachtold

Activities:

Our group focuses on the mesoscopic investigation of both quantum electron transport and mechanical resonators. We explore phenomena based on electron correlation, quantum effects, and topology in novel condensed matter systems such as twisted bilayer graphene stacks and one- and two-dimensional single crystals. We also use such systems to produce mechanical resonators endowed with enhanced quantum fluctuations and ultra-long life times, which are at the heart of the renaissance in mechanics.
