Recombination of three ultracold fermionic atoms

H. Suno, B. D. Esry, Chris H. Greene

Three-body recombination of identical, spin-polarized fermionic atoms in the ultracold limit is investigated. The mechanisms for recombination are described in terms of the ``scatt…

Linking Ultracold Polar Molecules

A. V. Avdeenkov, J. L. Bohn

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…

Feshbach Resonance Cooling of Trapped Atom Pairs

J. W. Dunn, D. Blume, Bogdan Borca +2

Spectroscopic studies of few-body systems at ultracold temperatures provide valuable information that often cannot be extracted in a hot environment. Considering a pair of atoms, w…

Competition among molecular fragmentation channels described with Siegert channel pseudostates

Edward L. Hamilton, Chris H. Greene

To describe multiple interacting fragmentation continua, we develop a method in which the vibrational channel functions obey outgoing wave Siegert boundary conditions. This paper d…

Formation of atomic tritium clusters and condensates

D. Blume, B. D. Esry, C. H. Greene +2

We present an extensive study of the static and dynamic properties of systems of spin-polarized tritium atoms. In particular, we calculate the two-body |F,m_F>=|0,0> s-wave scatter…

Rotational Feshbach Resonances in Ultracold Molecular Collisions

J. L. Bohn, A. V. Avdeenkov, M. P. Deskevich

In collisions at ultralow temperatures, molecules will possess Feshbach resonances, foreign to ultracold atoms, whose virtual excited states consist of rotations of the molecules.…

Collisional dynamics of ultracold OH molecules in an electrostatic field

Alexandr V. Avdeenkov, John L. Bohn

Ultracold collisions of polar OH molecules are considered in the presence of an electrostatic field. The field exerts a strong influence on both elastic and state-changing inelasti…

Three particles in an external trap: Nature of the complete J=0 spectrum

D. Blume, Chris H. Greene

Three bosonic, spin-polarized atoms in a spherical oscillator potential constitutes the simplest nontrivial Bose-Einstein condensate (BEC). The present paper develops the tools nee…
