Ultracold atomic gases offer a versatile platform for exploring rich phenomena in quantum matter. In particular, topological states akin to those found in the quantum Hall effect can be engineered by simulating orbital magnetic fields—an approach greatly facilitated by the use of synthetic dimensions.
In this talk, I will present our experimental realization of a quantum Hall system using...
Single-Shot Coherent Diffractive Imaging (CDI) has become a mature tool to capture the structure and dynamics of nanoscale systems such as viruses [1], nanoparticles [2] and helium droplets in free flight [3]. The conventional application of the underlying single-shot imaging implies that the imaging pulse interacts instantly and perturbatively with the target such that the diffraction image...
Helium nanodroplets are quantum fluid clusters that feature extraordinary properties such as ultralow temperature and superfluidity. They have mostly been used as inert nanometer-sized cryo-matrices for isolating molecules and for aggregating molecular complexes and nanostructures that are hard or impossible to form by other means. However, when helium nanodroplets are resonantly excited or...
In this communication we present how ionizing radiation influences the formation of peptide bonds in clusters of amino acids in the gas phase. In the past, simulations and experiments were carried out in parallel to understand the possible mechanisms involved[1,2]. Due to these promising previous results, we have expanded the study, including clusters of other amino acids. The main objective...
Nanoparticle (NP) mass spectrometry in the gas phase is a unique way
to characterize individual isolated particles and thus assess their
intrinsic properties, NP-to-NP variability and structural evolution,
e.g. in studies on charging mechanisms [1], photophysics [2] or high
temperature reaction kinetics [3]. Our group focuses on cryogenic
experiments to employ absorption spectroscopy,...
