چکیده

Recombination of identical, spin-polarized fermions in cold threebody collisions is investigated. We parametrize the mechanisms for recombination in terms of the ‘scattering volume’ Vp and another length scale r0. Model two-body interactions were used within the framework of the adiabatic hyperspherical representation. We examine the recombination rate K3 as a function of the collision energy E for various values of Vp. Not only do we consider the dominant J = 1+ case, but also the next-leading order contributions from J = 1− and 3−. We discuss the behaviour near a two-body resonance and the expected universality of fermionic recombination. Comparisons with boson recombination are considered in detail.

Recombination of three ultracold fermionic atoms.

Three-body recombination of identical, spin-polarized fermionic atoms in the ultracold limit is investigated using model interactions. The mechanisms for recombination are parametrized by the "scattering volume" V(p) and described in the framework of the adiabatic hyperspherical representation. We have calculated the recombination rate K3 as a function of V(p) and have found K3 proportional, va...

We discuss three-body recombination of ultra-cold atoms to a weakly bound s level. In this case, characterized by large and positive scattering length a for pair interaction, we find a repulsive effective potential for three-body collisions , which strongly reduces the recombination probability and makes simple Jastrow-like approaches absolutely inadequate. In the zero temperature limit we obta...

Bose-fermi mixtures in a three-dimensional optical lattice.

We have studied mixtures of fermionic (40)K and bosonic (87)Rb quantum gases in a three-dimensional optical lattice. We observe that an increasing admixture of the fermionic species diminishes the phase coherence of the bosonic atoms as measured by studying both the visibility of the matter wave interference pattern and the coherence length of the bosons. Moreover, we find that the attractive i...

Suppression of molecular decay in ultracold gases without Fermi statistics.

We study inelastic processes for ultracold three-body systems in which only one interaction is resonant. We show that at ultracold temperatures three-body recombination in such systems leads mainly to the formation of weakly bound molecules. In addition, and perhaps more importantly, we have found that the decay rates for weakly bound molecules due to collisions with other atoms can be suppress...

Spin-orbit coupling and perpendicular Zeeman field for fermionic cold atoms: Observation of the intrinsic anomalous Hall effect

We propose a scheme for generating Rashba spin-orbit coupling and a perpendicular Zeeman field simultaneously for cold fermionic atoms in a harmonic trap through the coupling between atoms and laser fields. The realization of Rashba spin-orbit coupling and a perpendicular Zeeman field provides opportunities for exploring many topological phenomena using cold fermionic atoms. We focus on the int...
