The authors demonstrate experimentally the creation of dual-species Bose-Einstein condensates ${}^{23}$Na atoms and ${}^{133}$Cs atoms. mixture is shown to be miscible have a long lifetime tens seconds, which could potentially allow ground-state NaCs molecules in future.

We consider a mixture of one-dimensional strongly interacting Fermi gases with up to six components, subjected to a longitudinal harmonic confinement. In the limit of infinitely strong repulsions we provide an exact solution which generalizes the one for the two-component mixture. We show that an imbalanced mixture under harmonic confinement displays partial spatial separation among the compone...

Abstract. We consider a system of Gross–Pitaevskii equations in R modelling a mixture of two Bose–Einstein condensates with repulsive interaction. We aim to study the qualitative behaviour of ground and excited state solutions. We allow two different harmonic and off-centered trapping potentials and study the spatial patterns of the solutions within the Thomas– Fermi approximation as well as ph...

Trans [1] is a Lisp system at the Space Telescope Science Institute (STScI) which is a key part of the proposal preparation ground system for the Hubble Space Telescope (HST). It was originally developed in the late ‘80s using a mixture of procedural, and blackboard architectures. While the original application met its requirements and performed well for a number of years, the increasing comple...

We analyze the ground-state phase diagram of an ultracold Bose-Fermi mixture placed in an optical lattice. The quantum phases involve pairing of fermions and one or several bosons. Depending on the physical parameters these composites can form a Fermi liquid, a density wave, a superfluid or a domain insulator. We determine by means of a mean-field formalism the phase boundaries for finite tunne...

We discuss ground state properties of a mixture of two fermion species which can bind to form a molecular boson. When the densities of the fermions are unbalanced, one or more Fermi surfaces can appear: we describe the constraints placed by Luttinger’s theorem on the volumes enclosed by these surfaces in such Bose-Fermi mixtures. We also discuss the nature of the quantum phase transitions invol...

We report on the observation of Feshbach resonances in an ultracold mixture of two fermionic species, (6)Li and (40)K. The experimental data are interpreted using a simple asymptotic bound state model and full coupled channels calculations. This unambiguously assigns the observed resonances in terms of various s- and p-wave molecular states and fully characterizes the ground-state scattering pr...

general toxicity, antiproliferative, antibacterial and antioxidant activities of caulerpa peltata j.v.lamouroux (caulerpaceae) collected from oman sea were investigated. dried, ground alga was soxhlet-extracted with hexane, dichloromethane and methanol successively. the methanol extract was subjected to vacuum liquid chromatography (vlc) fractionation on silica gel using a step gradient of diff...
