Many body physics using alkaline-earth atoms — •Rick Mukherjee1, James Millen2, Rejish Nath3, Matthew Jones2, and Thomas Pohl11Max Planck Institute for the Physics of Complex Systems, Dreden, Germany — 2Durham University, United Kingdom — 3Institute for theoretical physics, University of Innsbruck

We show that alkali earth metals offer a promising possibility of trapping ions as well as atoms in ground and highly excited Rydberg states in a common lattice potential [1]. Considering optical core-dressing, we identify experimentally accessible magic wavelengths to achieve this simultaneous trapping for the case of Strontium. We discuss various loss mechanisms and show that the additional lattice potential does not induce additional lifetime limitations even for rather large trapping frequencies. By exploiting the Rydberg interactions, applications for studying many-body dynamics such as generating many-body entanglement are also discussed.
