Production of ultracold Cs*Yb molecules by photoassociation [PDF]
Physical Review A, 2018 We report the production of ultracold heteronuclear Cs∗ Yb molecules through one-photon photoassociation applied to an ultracold atomic mixture of Cs and Yb confined in an optical dipole trap.

Two-photon photoassociation spectroscopy of CsYb: Ground-state interaction potential and interspecies scattering lengths [PDF]
Physical Review A, 2018 We perform two-photon photoassociation spectroscopy of the heteronuclear CsYb molecule to measure the binding energies of near-threshold vibrational levels of the $X{\phantom{\rule{3.33333pt}{0ex}}}^{2}{\mathrm{\ensuremath{\Sigma}}}_{1/2}^{+}$ molecular ...

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.

Tuning the scattering length with an optically induced Feshbach resonance [PDF]
, 2004 We demonstrate optical tuning of the scattering length in a Bose-Einstein condensate as predicted by Fedichev {\em et al.} [Phys. Rev. Lett. {\bf 77}, 2913 (1996)].

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 ...

Pulsed adiabatic photoassociation via scattering resonances [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2011 We develop the theory for the Adiabatic Raman Photoassociation (ARPA) of ultracold atoms to form ultracold molecules in the presence of scattering resonances. Based on a computational method in which we replace the continuum with a discrete set of "effective modes", we show that the existence of resonances greatly aids in the formation of deeply bound ...

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 ...

Photoassociation spectroscopy of cold calcium atoms [PDF]
, 2002 Photoassociation spectroscopy experiments on 40Ca atoms close to the dissociation limit 4s4s 1S0 - 4s4p 1P1 are presented. The vibronic spectrum was measured for detunings of the photoassociation laser ranging from 0.6 GHz to 68 GHz with respect to the ...

Photoassociation of Trilobite Rydberg Molecules via Resonant Spin-Orbit Coupling. [PDF]
Physical Review Letters, 2017 We report on a novel method for the photoassociation of strongly polar trilobite Rydberg molecules. This exotic ultralong-range dimer, consisting of a ground-state atom bound to the Rydberg electron via electron-neutral scattering, inherits its polar ...
