Photoassociation inside an optical dipole trap: absolute rate coefficients and Franck-Condon factors

, 2004
We present quantitative measurements of the photoassociation of cesium molecules inside a far-detuned optical dipole trap. A model of the trap depletion dynamics is derived which allows to extract absolute photoassociation rate coefficients for the ...

Quantum theory of a magneto-optical trap

Physical Review A
We present a quantum theory of a magneto-optical trap (MOT) from first principles based on the quantum kinetic equation for the atomic density matrix with taking into account the recoil effects caused by the interaction of atoms with the laser field. An efficient method for solving the quantum kinetic equation is proposed.

The scale matters: A review on stimuli‐responsive microrobots categorized by scale for biomedical applications

Responsive Materials, EarlyView.
We systematically summarize how each scale dictates fundamental choices in design feature, manufacturing technology, driving mechanism, and control strategy, which are inherently governed by scale‐dominated physical principles. Furthermore, the application of scale‐determined operation modes of microrobots across different stages of medical ...

Historical foreword: Jean Dalibard, the magneto-optical trap, and the ascent of physics with cold atomic gases

Comptes Rendus. Physique
I present my personal perspective on the importance of the invention by Jean Dalibard of the magneto-optical trap (MOT), which has for many years been the “workhorse” of the field of laser cooling and cold atomic gases.

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

Small, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Trapping of ultracold polar molecules with a Thin Wire Electrostatic Trap

, 2007
We describe the realization of a dc electric-field trap for ultracold polar molecules, the thin-wire electrostatic trap (TWIST). The thin wires that form the electrodes of the TWIST allow us to superimpose the trap onto a magneto-optical trap (MOT).

Optical‐controlled magnon transport based on spin crossover switched molecular magnets

Smart Molecules, EarlyView.
A cyanide‐bridged W(V)–Fe(II) spin‐crossover single crystal was integrated into a magnon transport device, enabling reversible optical control of magnon transport through photo‐switched spin states. Abstract Molecule‐based devices that combine the advantages of fast time response and extremely low manipulation/transmission energy consumption of light ...
