The repulsive 1D Bose gas is an emblematic model of many-body quantum physics whose solutions are known since the 60 s. However it is only recently that experiments with ultracold atoms in tight waveguides allowed to test the theory also raising new puzzles. This manus... Lees meer.

Experiments have similarly not been able to observe coherent vortex dynamics. This thesis resolves this challenge bringing microphotonic techniques to bear on two-dimensional superfluid helium observing coherent vortex dynamics for the first time and achieving this o... Lees meer.

This thesis focuses on the study of the optical response of new atomically thin two-dimensional crystals principally the family of transition metal dichalcogenides like MoS2. One central theme of the thesis is the precise treatment of the linear and second-order nonlin... Lees meer.

This thesis explores the physics of non-equilibrium quantum dynamics in homogeneous two-dimensional 2D quantum gases. Ultracold quantum gases driven out of equilibrium have been prominent platforms for studying quantum many-body physics. However probing non-equilibri... Lees meer.

Superfluid helium is a quantum liquid that exhibits a range of counter-intuitive phenomena such as frictionless flow. Quantized vortices are a particularly important feature of superfluid helium and all superfluids characterized by a circulation that can only take pre... Lees meer.
