Title: Ultralong-range and ultracold Rydberg molecules: a new molecular bonding

Abstract: How Rydberg atoms are perturbed in the presence of ground state atoms is an old subject. In this talk, I describe several exotic classes of ultralong and ultracold Rydberg molecules, bound by a "Rydberg" bond, and with fascinating properties. A subset of these molecules have recently been realized in the lab and are by far the largest molecules ever created. I will discuss a new set of ulralong Rydberg molecules formed due to the interaction of Rydberg atoms and polar molecules and how the orientation of the ultracold polar molecule can be controlled in a Raman scheme.
