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 ...

Observation of photoassociation resonances in ultracold atom-molecule collisions [PDF]
, 2023 Photoassociation of ultracold atoms is a resonant light-assisted collision process, in which two colliding atoms absorb a photon and form an excited molecule.

Feshbach resonance-induced Fano interference in photoassociation [PDF]
, 2009 We consider photoassociation from a state of two free atoms when the continuum state is close to a magnetic field-induced Feshbach resonance and analyse Fano interference in photoassociation.

Photoassociation of metastable helium
A theoretical study is performed for the photoassociation of metastable helium. Combining short-range, high-level, ab initio calculations for 5sumg/u+ and 5∏g/u symmetries and long-range behaviour, better described in Hund\u27s case (c), potential-energy

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 ...

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.

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

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 ...

On‐Command Regulation of Kinase Activity using Photonic Stimuli
ChemPhotoChem, Volume 3, Issue 6, Page 318-326, June 2019., 2019 Moving on up: To better understand the relationship between kinase activity and cellular behaviour, the use of light as an external stimulus to modulate kinase activity with high spatiotemporal resolution has gained increasing interest of late. Herein we highlight the progress made towards the development of light‐responsive kinase enzymes and small ...

Polaritonic ultracold reactions: cavity controlled molecular photoassociation [PDF]
, 2023 We introduce a prototypical model for cavity polaritonic control of ultracold photochemistry by considering the resonant vibrational strong coupling of a rubidium dimer to a terahertz cavity. We demonstrate that at avoided crossings between a vibrational
