Pair Correlations and Photoassociation Dynamics of Two Atoms in an Optical Tweezer. [PDF]
Physical Review Letters, 2020 We investigate the photoassociation dynamics of exactly two laser-cooled ^{85}Rb atoms in an optical tweezer and reveal fundamentally different behavior to photoassociation in many-atom ensembles.

Nonlinear photoassociation through exotic orbits
Physical Review E, 2021 We investigate the effects of a particular kind of orbits, which we call exotic orbits, on the process of classical molecular photoassociation. As a starting model system, we consider the process described by the Morse potential with a time-dependent perturbation consisting of the interaction of an external laser field with the molecular dipole.

Steering thermal photoassociation of magnesium atoms by two time-delayed femtosecond laser pulses
Frontiers in Physics, 2023 By solving the full-dimensional time-dependent Schrödinger equation with the thermal-random-phase wavepacket method, we investigate the photoassociation (PA) process of hot (1000 K) magnesium atoms induced by two time-delayed femtosecond laser pulses ...

Precision measurement of atom-dimer interaction in a uniform planar Bose gas
Physical Review Research, 2023 Cold quantum gases, when acted upon by electromagnetic fields, can give rise to samples where isolated atoms coexist with dimers or trimers, which raises the question of the interactions between these various constituents.

Microwave coherent control of ultracold ground-state molecules formed by short-range photoassociation. [PDF]
Physical Chemistry, Chemical Physics - PCCP, 2020 We report the observation of microwave coherent control of rotational states of ultracold 85Rb133Cs molecules formed in their vibronic ground state by short-range photoassociation.

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 ...
