“…The subject of long-range interactions of Yb atoms and Yb-alkali atoms has recently became of much interest owing to study of quantum gas mixtures [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], development of optical lattice clocks [20,21], study of fundamental symmetries [22], quantum computing [23] and practical realization of quantum simulation proposals [24][25][26]. Yb is a particularly suitable candidate for all of these applications owing to its five bosonic and two fermionic stable isotopes in natural abundance, the 1 S 0 ground state, the long-lived metastable 6s6p Presently, there is much interest in forming cold molecules with both electric and magnetic dipole moments because of the greater possibilities for trapping and manipulation [2,6,17,18,27].…”

Relativistic many-body calculations of van der Waals coefficients for Yb-Li and Yb-Rb dimers

We derive the relativistic formulas for the van der Waals coefficients of Yb-alkali dimers that correlate to ground and excited separated-atom limits. We calculate C6 and C8 coefficients of particular experimental interest. We also derive a semi-empirical formula that expresses the C8 coefficient of heteronuclear A + B dimers in terms of the C6 and C8 coefficients of homonuclear dimers and the static dipole and quadrupole polarizabilities of the atomic states A and B. We report results of calculation of the C6 coefficients for the Yb-Rb

“…This photoassociative tuning becomes possible due to the existence of long-lived excited molecular states near the narrow intercombination lines of the alkaline-earth-like atoms.

We theoretically evaluate the feasibility to form magnetically-tunable Feshbach molecules in collisions between fermionic 6 Li atoms and bosonic metastable 174 Yb( 3 P 2 ) atoms. In contrast to the well-studied alkali-metal atom collisions, collisions with meta-stable atoms are highly anisotropic. Our firstprinciple coupled-channel calculation of these collisions reveals the existence of broad Feshbach resonances due to the combined effect of anisotropic-molecular and atomic-hyperfine interactions. In order to fit our predictions to the specific positions of experimentally-observed broad resonance structures (Dowd et al 2014) we optimized the shape of the short-range potentials by direct leastsquare fitting. This allowed us to identify the dominant resonance by its leading angular momentum quantum numbers and describe the role of collisional anisotropy in the creation and broadening of this and other resonances.The formation of ultracold molecules with a single unpaired electron allowing for coupling of the electron spin with the rotational angular momentum of the molecule has received increasing interest [2][3][4]. For example, the authors in [2] proposed that such spin-rotational splitting of Σ + 2 molecular rotational states can make the longrange electric dipole-dipole interaction between molecules spin-dependent. Then, these molecules confined in two-dimensional optical lattices create a class of ultracold molecules that can realize spin-lattice models with unique topological properties.Ultracold Σ + 2 molecules can be formed from an alkali-metal and an alkaline-earth-like atom in the ground or even long-lived metastable states. Experimental efforts toward production of these ground-state molecules are in their initial stages [1,[5][6][7][8][9]. The success of these experiments significantly depends on the realization of a two-step process, when a mixed quantum gas of alkali-metal and alkaline-earth-like atoms is first optically associated into weakly-bound molecules, which are then transferred into the rovibrational ground state.Photoassociation for homonuclear alkaline-earth-like molecules via so-called optical Feshbach tuning was pioneered by [10][11][12]. This photoassociative tuning becomes possible due to the existence of long-lived excited molecular states near the narrow intercombination lines of the alkaline-earth-like atoms. Recent successful experiments [13][14][15][16] showed that a two-photon optical Feshbach resonance can be used to couple two colliding atoms to a vibrational level of the molecular ground state. The suppressed excited-state spontaneous decay makes efficient coherent molecular formation possible.An alternative method to form ultracold molecules from ultracold atoms is by magneto-association. Magnetic Feshbach resonances have had an enormous impact on the field of laser-cooled ultra-cold atoms and molecules [17][18][19][20][21]. These resonances have allowed a tunable, variable interaction strength by simply varying the strength of an external magnetic field (typically on the ord...

“…We take laser intensity 10 mW/cm 2 . Figure3 shows that V 0 varies with δĒ reaching a maximum of about 440 Hz at δĒ = 0.5γ, where we have set γ = 364 kHz which is taken to be double the atomic linewidth of 182 kHz [68]. When δĒ is negative V 0 is positive implying the existence of trapping potential, but when δĒ is positive V 0 becomes negative showing no trapping is possible.…”

Photoassociative cooling and trapping of a pair of interacting atoms

We show that it is possible to cool interacting pairs of atoms by a lin ⊥ lin Sisyphus-like laser cooling scheme using counter-propagating photoassociation (PA) lasers. It is shown that the center-of-mass motion (c.m.) of atom pairs can be trapped in molecular spin-dependent periodic potentials generated by the lasers.The proposed scheme is most effective for narrow-line PA transitions. We illustrate this with numerical calculations using fermionic 171 Yb atoms as an example.
