Prof Kristian Helmerson (Monash) has performed ground-breaking experiments in the fields of ultracold collisions of atoms, matter-wave optics, nonlinear dynamics with atoms, superfluidity of atomic gases and atomtronics; he was instrumental in establishing the field of nonlinear atom optics. Kris led FLEET’s Research Theme 3, where the team utilises ultracold atoms in an optical lattice as a model system to investigate (i) dissipation and equilibration in driven Floquet systems and (ii) the creation of topological states in multi-dimensional extensions of the kicked quantum rotor.
