The intimate connection between topology and quantum physics has been widely explored in solid-state physics, revealing a plethora of remarkable physical phenomena over the years. Building on their universal nature, topological properties are currently studied in an even broader context, ranging from ultracold atomic gases to photonics, where distinct observables and probes offer a novel view on topological quantum matter.
In this seminar, I will start by presenting a brief overview of our recent research activities, setting the focus on the realization and detection of topological properties in ultracold atoms.
I will then dedicate the main part of the seminar to a very recent work , where we demonstrate that an intriguing topological phenomenon can be unveiled upon « heating » lattice systems.
