About the group

Cavity-Optomechanics provides a unique approach to Stochastic and Quantum Thermodynamics at the single- and few particle level. The thermodynamic perspective on overdamped mechanical systems has been successfully and much more extensively studied than on well-isolated mechanics. We experimentally investigate such underdamped mechanical systems. Amongst others, this provides a natural first step towards the quantum regime. Our focus lies on the application of levitated optomechanics, where all-optical control of the potential landscape seen by a single or few nanoparticles and reservoir engineering of their optical environment are possible. This will provide a general testbed for proof-of-principle implementations to experimentally adress questions at the interface of thermodynamics, information theory and quantum physics.

The experimental group on Stochastic and Quantum Thermodynamics is led by Assist.-Prof. Dr. Nikolai Kiesel. The research is mainly funded by the FWF START Programme and hosted by the group of Prof. Aspelmeyer at the Faculty of Physics, key research area Quantum Optics, Quantum Nanophysics and Quantum Information.
