Group Seminar via Zoom: Single-Site Resolved Imaging and Addressing of 87Rb Atoms in a Quantum Gas Microscope

February 15, 2022

Clemens Ulm, University of Strathclyde, Glasgow
Group meeting via video conference (Zoom)
Tuesday, February 15, 9:00 am (MEZ)

Due to the Covid-19 pandemic, the group seminar will be a hybrid event, allowing participants to attend the seminar virtually and in-person. This procedure enables us to continue our research, enhance discussions and exchange important information.


Quantum gas microscopes (QGMs) allow for the direct observation of quantum effects in many-body systems by site-resolved imaging of single atoms in optical lattices. I will present the results of two projects in the group of Stefan Kuhr at the University of Strathclyde. We numerically compared the performance of three popular deconvolution techniques by simulating the imaging process. The atom detection fidelities were measured as a function of various imaging parameters such as signal-to-noise ratio, occupation fraction, fluorescence inhomogeneity, and microscope magnification. Secondly, I will report on the implementation of a digital micro-mirror device (DMD) into a Rb QGM.Utilizing three distinct wavelengths of light, the DMD can both address single atoms and project arbitrary light potentials to realise more complex multi-body systems.
