Activities

We investigate quantum electrical, mechanical, and optical properties of nanofabricated devices based on condensed matter systems, such as twisted bilayer graphene and carbon nanotube.

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 electromechanical resonators endowed with enhanced quantum fluctuations and ultra-long life times, which are at the heart of modern advances in nanomechanics.

Positions at Master-thesis, PhD and Postdoctoral level available. Please contact Prof. Dr.Adrian Bachtold for further information.
