The Chair of Nano & Quantum Sensors is working on the experimental investigation of advanced nanostructures with novel or hybrid functionalities with a particular focus on sensing applications both in the classical and in the quantum regime. Our expertise lies in the cleanroom-based fabrication of nanostructures as well as in their characterization with state-of-the-art measurement techniques.

The research of the chair led by Eva Weig is focussing on nanomechanical and cavity optomechanical systems. These freely-suspended nanostructures exhibit discrete vibrational modes with high mechanical quality factor. We explore their vibrational properties with a special emphasis on aspects of dissipation, nonlinear dynamics, coupling and coherent control. Of particular interest is the integration of the mechanical resonator with optical or microwave cavities which allows for the additional exploitation of radiation-pressure induced backaction, which provides access to the quantum regime of nanomechanics.
