Physico-chemical processes in planet-forming disks Planets form in so-called protoplanetary disks. These are astrophysical objects where
the remaining masses of gas and dust after star formation keep on rotating around the
new-born star for a few million years. On this timescale, we believe that micron-sized
dust particles c ... more |

Resonant states and their role in nanophotonics Resonant phenomena have been extensively used in micro- and nanophotonics. These phenomena originate in a discrete set of basis functions known as resonant states or quasi-normal modes that are eigensolutions of Maxwell’s equations. I will introduce the fundamental principles a ... more |

Oscillatory Dynamics at Catalytically Active Interfaces Studied by Multi-Scale Operando Electron Microscopy Our aim is to understand processes that lead to the emergence of catalytic function though direct observation using a combination of operando scanning and transmission electron microscopy. Starting with simple model catalysts, such as polycrystalline metal foils, we observe the p ... more |

A complementary approach to quantify weak interactions in protein solutions with high throughput Weak interactions are predominantly responsible for proteins to form complex colloids and solutions [1]. However, they are not fully understood yet. When studying solutions, weak interactions are often characterized using the osmotic second viral coefficient (B22) that describes ... more |

Quantum choreography to the beat of light Lightwave electronics has pushed the control of condensed matter to unprecedented time scales. By harnessing the carrier wave of intense light as an alternating voltage, electrons can be driven faster than a cycle of light, opening a fascinating quantum world full of promise fo ... more |

Structuring light for controlled propagation and manipulation Designing non-trivial light distributions, and controlling them during propagation, is of interest for modern optical technologies and
particle/atom trapping. In this presentation I will show how light carrying orbital angular momentum (OAM) can be used to generate optical solit ... more |

Femto- phono- magnetism From the outset of research into femtomagnetism, the field in which spins are manipulated by light on femtosecond or faster time scales, several questions have arisen and remain highly debated: How does the light interact with spin moments? How is the angular momentum conserved ... more |

Molecular photoacoustic imaging of contrast agents using pump-probe excitation Biomedical photoacoustic imaging relies on the absorption and thermalisation of optical excitation pulses to generate and detect ultrasound waves in tissue from which high-resolution images (tens of microns) are reconstructed. The images show the initial pressure distribution, wh ... more |
