A homonuclear polar molecule — •Hossein Sadeghpour — ITAMP- harvard-smithsonian center for astrophysics, cambridge, ma 02138

Manipulating Rydberg interactions in ultracold ensemble is currently in vogue due to the long-range nature of forces and large dipole moments. Interactions between ultracold Rydberg and ground state atoms lead for formation of exotic classes of Rydberg molecules with peculiar properties. A particular class of such molecules was recently observed in Stuttgart and was found to sport significant permanent electric dipole moment, even though that the molecules themselves were homonuclear. In this presentation, I will describe the physics of the formation of permanent dipole moments in homonuclear species, arising from symmetry breaking. The work has appeared in Science Vol. 334 no. pp. 1110-1114, 2011, in collaboration with MPIPKS and Univ. of Stuttgart.
