Robert’s expertise includes fundamental tests of quantum mechanics in ultracold atomic gases, in particular how one can generate, characterize and exploit entanglement and non-classical correlations in these systems. Robert is also studying non-equilibrium quench dynamics and many-body physics in quantum spin models. In particular, he is interested in how correlations and entanglement develop in lattice models, and how novel physical phenomena can arise due to disorder and dissipation. He uses advanced and emerging numerical techniques, such as discrete phase-space methods, to study these systems in experimentally realistic scenarios.
