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 ...

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 ...

Microscopic electronic structure tomography of Rydberg macrodimers
Physical Review Research, 2021 Precise control and study of molecules is challenging due to the variety of internal degrees of freedom and local coordinates that are typically not controlled in an experiment.

Photoassociation spectroscopy of ultracold metastable 3He dimers [PDF]
Physical Chemistry Chemical Physics, 2011 The bound states of the fermionic ^3He(2 ^3S_1)+ ^3He(2 ^3P_j)system, where j=0,1,2, are investigated using the recently available ab initio short-range ${}^{1,3,5} ^{+}_{g,u}$ and ${}^{1,3,5} _{g,u}$ potentials computed by Deguilhem et al. (J. Phys. B: At. Mol. Opt. Phys., 2009, 42, 015102).

Observation of spin-orbit-dependent electron scattering using long-range Rydberg molecules
Physical Review Research, 2020 We present experimental evidence for spin-orbit interaction of an electron as it scatters from a neutral atom. The scattering process takes place within a Rb_{2} ultralong-range Rydberg molecule, consisting of a Rydberg atomic core, a Rydberg electron ...

Optical Feshbach resonances of Alkaline-Earth atoms in a 1D or 2D optical lattice [PDF]
, 2006 Motivated by a recent experiment by Zelevinsky et al. [Phys. Rev. Lett. 96, 203201], we present the theory for photoassociation and optical Feshbach resonances of atoms confined in a tight one-dimensional (1D) or two-dimensional (2D) optical lattice.

Cavity-controlled formation of ultracold molecules
New Journal of Physics, 2018 Ultracold ground-state molecules can be formed from ultracold atoms via photoassociation followed by a spontaneous emission process. Typically, the molecular products are distributed over a range of final states. Here, we propose to use an optical cavity

Enhancement of ultracold molecule formation by local control in the nanosecond regime
New Journal of Physics, 2015 We describe quantum simulations of ultracold ^87 Rb _2 molecule formation using photoassociation (PA) with nanosecond-time-scale pulses of frequency chirped light.

Sub-Natural-Linewidth Quantum Interference Features Observed in Photoassociation of a Thermal Gas [PDF]
, 2005 By driving photoassociation transitions we form electronically excited molecules (Na$_2^*$) from ultra-cold (50-300 $\mu$K) Na atoms. Using a second laser to drive transitions from the excited state to a level in the molecular ground state, we are able ...
