Caesium Quantum Gas Microscope

Caesium Quantum Gas Microscope

A quantum gas microscope for strongly interacting topological phases.

This is a collaboration with the group of Monika Aidelsburger. We have built a new Quantum Gas Microscope experiment with bosonic Caesium atoms at LMU to study topological many-body phases of matter. We will make use of the unique possibilities offered by high-resolution imaging techniques to investigate topological many-body phenomena in these lattices.


2023/06 Our new preprint titled ‘Emergence of fluctuating hydrodynamics in chaotic quantum systems’ is now on the arXiv.

2022/12 Just in time for christmas, we finished a publication about our deep-learning based single-site reconstruction scheme.

We propose a novel technique based on a convolutional autoencoder which enables us to reconstruct the lattice occupation with high fidelity even though our lattice spacing is more than two times smaller than our imaging resolution (383.5nm lattice spacing vs. 850nm Rayleigh resolution).
