My Research Interests

I am broadly interested in open quantum systems, especially in the context of cold-atom physics. One aspect of my research aims to understand the ultimate capabilities of thermal machines whose working medium comprises a small quantum system, like a single trapped atom or ion [3,5]. Studying such systems gives insight into the quantum foundations of thermodynamics, and may eventually lead to improved methods for cooling atomic motion, which is an indispensable precursor for any quantum technology based on cold atoms. I also work on problems relating to atomic impurities in ultracold gases. Here, the properties of the ultracold gas leave detectable imprints on the evolution of the impurities immersed within it. The impurities can therefore behave as highly tunable, non-destructive measurement devices, which may facilitate precise thermometry at extremely low temperatures, for example [2,4].
