Frontiers in Physics, 2023 It is crucial to control the collision between ultracold atoms by applying external fields. We developed a theoretical model for investigating the s-wave scattering of ultracold atoms controlled by the magnetic field and laser field.

Ultracold 88Sr2 molecules in the absolute ground state
New Journal of Physics, 2021 We report efficient all-optical creation of an ultracold gas of alkaline-earth-metal dimers, ^88 Sr _2 , in their absolute ground state. Starting with weakly bound singlet molecules formed by narrow-line photoassociation in an optical lattice, followed ...

Photoassociation of spin-polarized chromium [PDF]
Physical Review A, 2016 We report the homonuclear photoassociation (PA) of ultracold ${}^{52}\mathrm{Cr}$ atoms in an optical dipole trap. This constitutes the first measurement of PA in an element with total electron spin $\tilde{S}>1$. Although Cr, with its ${}^{7}\mathrm{S}_{3}$ ground and ${}^{7}\mathrm{P}_{4,3,2}$ excited states, is expected to have a complicated PA ...

Photoassociation of ultracold long-range polyatomic molecules
Physical Review Research, 2021 We explore the feasibility of optically forming long-range tetratomic and larger polyatomic molecules in their ground electronic state from ultracold pairs of polar molecules aligned by external fields.

Long-range Rydberg-atom–ion molecules of Rb and Cs
Physical Review Research, 2021 We propose a novel type of Rydberg dimer, consisting of a Rydberg-state atom bound to a distant positive ion. The molecule is formed through long-range electric-multipole interaction between the Rydberg atom and the pointlike ion.

New Journal of Physics, 2020 We propose a scheme to realize a heavy Rydberg system (HRS), a bound pair of oppositely charged ions, from a gas of ultracold atoms. The intermediate step to achieve large internuclear separations is the creation of a unique class of ultra-long-range ...

Effects of a static electric field on two-color photoassociation between different atoms
AIP Advances, 2014 We study non-perturbative effects of a static electric field on two-color photoassociation of different atoms. A static electric field induces anisotropy in scattering between two different atoms and hybridizes field-free rotational states of ...

Physical Review Research, 2023 We report on photoassociation spectroscopy probing the c^{3}Σ_{1}^{+} potential of the bialkali NaCs molecule, identifying 11 vibrational lines between v^{′}=0 and v^{′}=25 of the excited c^{3}Σ_{1}^{+} potential and fitting their rotational and ...

Continuous formation of vibronic ground state RbCs molecules via photoassociation
New Journal of Physics, 2014 We demonstrate the direct formation of vibronic ground state RbCs molecules by photoassociation of ultracold atoms followed by radiative stabilization. The photoassociation proceeds through deeply bound levels of the (2) ^3 Π _0 ^+_+ state. From analysis
