Speaker: Guido Pupillo (University of Innsbruck) Title: Quantum phases of atoms and molecules with strong long-range interactions Time: Today, 15.15 Place: Fysisk Auditorium Abstract: Heteronuclear polar molecules prepared in the electronic and vibrational ground state and cold gases of Rydberg-excited alkali atoms provide examples of systems where long-range dipole-dipole interactions can dominate the system dynamics. In this talk we present recent theoretical results on the possibility of realizing quantum phases of matter with strong long-range interactions in the cold atom/molecule context, with a focus on dipole-dipole interactions. These phases include supersolid phases in the mesoscopic and thermodynamic regimes, as well as crystalline phases of cold Rydberg atoms and polar molecules. Peter Staanum og Nicolai Nygaard
