Atom-dimer scattering and long-lived trimers in fermionic mixtures.
We consider a heteronuclear fermionic mixture on the molecular side of an interspecies Feshbach resonance and discuss atom-dimer scattering properties in uniform space and in the presence of an external confining potential, restricting the system to a quasi-two-dimensional geometry. We find that there is a peculiar atom-dimer p-wave resonance which can be tuned by changing the frequency of the ...
متن کاملPhase separation in atom-molecule mixtures near a Feshbach resonance
We study the phase separation of a Bose-Einstein condensate system with the conversion of one-species bosonic atoms into molecules via Feshbach resonance. Adopting the Thomas-Fermi approximation, we plot the phase diagrams of the system in two different parameter spaces for different atom-molecule interactions. In the presence of an isotropic trap, the density profiles in spatial space with fix...
متن کاملDifferences in dimer-dimer interaction
The three-dimensional X-ray structure of a recombinant human mitochondrial manganese superoxide dismutase (MnSOD) (chain length 198 residues) was determined by the method of molecular replacement using the related structure of MnSOD from Thermus thermophilus as a search model. This tetrameric human MnSOD crystallizes in space group P2,2,2 with a dimer in the asymmetric unit (Wagner, U.G., Werbe...
متن کاملControlling integrability in a quasi-one-dimensional atom-dimer mixture
We analytically study the atom-dimer scattering problem in the near-integrable limit when the oscillator length l0 of the transverse confinement is smaller than the dimer size,∼ l2 0/|a|, where a < 0 is the interatomic scattering length. The leading contributions to the atom-diatom reflection and break-up probabilities are proportional to a6 in the bosonic case and to a8 for the ↑-↑↓ scattering...
متن کاملDimer Problems
The dimer model is a statistical mechanical model on a graph, where configurations consist of perfect matchings of the vertices. For planar graphs, expressions for the partition function and local statistics can be obtained using determinants. The planar dimer model can be used to model a number of other statistical mechanical processes such as the planar Ising model and free fermions. It is al...
