Collective Many-Body Interaction in Rydberg Dressed Atoms
Collective Many-Body Interaction in Rydberg Dressed Atoms
We present a method to control the shape and character of the interaction potential between cold atomic gases by weakly dressing the atomic ground state with a Rydberg level. For increasing particle densities, a crossover takes place from a two-particle interaction into a collective many-body interaction, where the dipole-dipole/van der …
