متن کاملProbing an Electron Scattering Resonance using Rydberg Molecules within a Dense and Ultracold Gas.
We present spectroscopy of a single Rydberg atom excited within a Bose-Einstein condensate. We not only observe the density shift as discovered by Amaldi and Segrè in 1934, but a line shape that changes with the principal quantum number n. The line broadening depends precisely on the interaction potential energy curves of the Rydberg electron with the neutral atom perturbers. In particular, we ...
متن کاملLinking ultracold polar molecules.
We predict that pairs of polar molecules can be weakly bound together in an ultracold environment, provided that a dc electric field is present. The field that links the molecules together also strongly influences the basic properties of the resulting dimer, such as its binding energy and predissociation lifetime. Because of their long-range character, these dimers will be useful in disentangli...
متن کاملUltracold Fermionic Feshbach Molecules
Date J The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. This thesis presents experiments creating heteronuclear diatomic molecules from ultracold mixtures of atomic bosons and fermions. The work presented takes advantage of a type of scatt...
متن کاملUltracold collisions of oxygen molecules
Collision cross sections and rate constants between two ground-state oxygen molecules are investigated theoretically at translational energies below ;1 K and in zero magnetic field. We present calculations for elastic and spin-changing inelastic collision rates for different isotopic combinations of oxygen atoms as a prelude to understanding their collisional stability in ultracold magnetic tra...
