Denis Uhland started his PhD in Physics at the University of British Columbia in Vancouver in 2018. He studied ultracold atomic ensembles and used Feshbach resonances to form atomic dimers. He was also involved in projects regarding the BEC-BCS crossover regime and cross-calibration of atomic pressure sensors. In 2022, he joined the light & matter group at the Leibniz University Hannover to continue and finish his PhD. He focuses on the fundamental quantum effects of hot atomic vapor cells and uses them for light filtration, quantum sensing, and magnetometers.
