Open quantum systems: Most systems are not fully isolated form their environments. For quantum systems, the presence of an environment can drastically change their behaviour. As the full system-plus-environment generally constitutes a complex many-body system, it is usual to work with heavy approximations such as vanishing coupling. In my work, I aim to go beyond those approaches and incorporate effects as the build-up of system-environment correlations by using both exact and perturbative methods.
Quantum thermodynamics: Traditionally thermodynamics treats macroscopic phenomena, where fluctuations are negligible. As systems gets smaller, fluctuations and eventually quantum effects become relevant. I am interested in the implications of strong coupling on the energy exchange between nanoscale systems and their reservoirs, i.e. heat and work. These in turn determine performance characteristics of quantum heat machines and refrigerators.
Quantum sensing: Quantum phenomena are highly fragile to the presence of an environment. In quantum sensing this is turned into an advantage by using it to design quantum sensors that are more sensitive to effects in their environment. My research focuses on temperature sensors and how they can be improved by the build-up of probe-sample correlations.
