“Scale invariance, a hidden symmetry explored with quantum gases”

Scale invariance, a concept initially introduced in high-energy physics, has gained numerous applications in the physics of quantum fluids. It is applicable to strongly interacting Fermi gases, two-dimensional Bose gases, as well as few-body systems that exhibit the “Efimov effect.” In this Memorial Lecture, I will illustrate how scale and conformal invariance emerge in cold atomic gases. I will use various examples ranging from thermodynamics to soliton physics to specific structures with periodic time evolution called “breathers”.
