Topological pumping as a method of creating a strongly correlated ideal Bose gas

In the past few decades, there has been a consistent stream of new experiments focusing onultracold atomic gases. These experiments often revolve around systems containing just a fewatoms confined in nearly one-dimensional traps and shed light on their counterintuitive quantum nature.One notable example is the experiment [Kao et al., Science 371, 2021], where researchersutilized the so-called topological pumping to generate excited states of a gas consisting ofdysprosium atoms. The states they obtained exhibited a range of unexpected properties,challenging conventional assumptions about non-interacting bosonic systems.In my talk, I intend to explore these fascinating characteristics in detail.
