“…The production of ultracold, heteronuclear, diatomic molecules in their ground state by coherently combining two di↵erent laser-cooled atomic species is currently an active research area [1][2][3][4] because of the potential for quantum information processing, [5][6][7][8][9][10][11] for cold chemistry, [12][13][14][15][16] the exploration of strongly interacting quantum systems [17][18][19][20] and precision measurement. [21][22][23][24] Heteronuclear molecules manifest an electric dipole moment when a direction is imposed by an electric field, 25 allowing study of long-range anisotropic interactions.…”

We describe the design, construction and operation of a versatile dual-species Zeeman slower for both Cs and Yb, which is easily adaptable for use with other alkali metals and alkaline earths. With the aid of analytic models and numerical simulation of decelerator action, we highlight several real-world problems affecting the performance of a slower and discuss effective solutions. To capture Yb into a magneto-optical trap (MOT), we use the broad $^1S_0$ to $^1P_1$ transition at 399 nm for the slower and the narrow $^1S_0$ to $^3P_1$ intercombination line at 556 nm for the MOT. The Cs MOT and slower both use the D2 line ($6^2S_{1/2}$ to $6^2P_{3/2}$) at 852 nm. We demonstrate that within a few seconds the Zeeman slower loads more than $10^9$ Yb atoms and $10^8$ Cs atoms into their respective MOTs. These are ideal starting numbers for further experiments on ultracold mixtures and molecules.Comment: 15 pages, 15 figures, 4 tables, revtex4-

“…The polar molecules produced so far include 40 K 87 Rb [1], 87 Rb 133 Cs [2,3], 23 Na 40 K [4], and 23 Na 87 Rb [5]. Such molecules have many potential applications, ranging from quantum-statecontrolled chemistry [6][7][8][9] to quantum simulation [10,11] and quantum information [12,13].…”

We present calculations of the hyperfine coupling constants for all the heteronuclear alkali-metal diatomic molecules at the equilibrium geometry of the electronic ground state. These constants are important in developing methods to control ultracold polar molecules. The results are based on electronic structure calculations using density functional theory, and are in good agreement with experiment for the limited set of molecules for which experiments are so far available

“…At the interface between atomic, molecular, optical, and condensed-matter physics, systems of ultracold polar molecules [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] have caused a great deal of excitement and opened a path for the quantum simulation [21][22][23][24][25][26][27][28][29] of quantum magnetism [30][31][32][33][34][35][36][37][38] and superconductivity [39,40] on optical lattices [41,42]. Intrinsic to these systems are the long-range dipolar-type interactions, which, in contrast to the long-range Coulomb interaction in condensed-matter systems, are not affected by screening.…”

Correlations and enlarged superconducting phase of t−J⊥ chains of ultracold molecules on optical lattices

We compute physical properties across the phase diagram of the t-J ⊥ chain with long-range dipolar interactions, which describe ultracold polar molecules on optical lattices. Our results obtained by the density-matrix renormalization group indicate that superconductivity is enhanced when the Ising component J z of the spin-spin interaction and the charge component V are tuned to zero and even further by the long-range dipolar interactions. At low densities, a substantially larger spin gap is obtained. We provide evidence that long-range interactions lead to algebraically decaying correlation functions despite the presence of a gap. Although this has recently been observed in other long-range interacting spin and fermion models, the correlations in our case have the peculiar property of having a small and continuously varying exponent. We construct simple analytic models and arguments to understand the most salient features.
