Thesis defense of Yukun GUO, PhD student in the Quantum gases group, on 14 March 2023 at 9am in the Auditorium of the Institut d'Optique in Palaiseau, on the topic: "3D Anderson transition of ultracold atoms in disordered potentials: observation of the mobility edge".
Abstract: "In this thesis, I present new results regarding the measurement of the mobility edge in the Anderson transition, which was conducted in the Quantum Gas group. Measuring the mobility edge of the Anderson transition is very challenging. The broad energy dispersion in the disordered potential was the major bottleneck for experimental research with ultralcold atoms in the past decade. To overcome this limitation, the team has proposed a spectroscopy scheme in state-dependent disorder to perform an energy-resolved loading of atoms in disorder by rf-transfer. Our team realized the rf-transfer in 2018. However, at that time, the limited lifetime of atoms in the disorder-sensitive state prevented the observation of transport of atoms in disorder.
