Magneto-optical trap mot
WebDec 14, 2024 · Direct laser cooling of molecules has reached a phase space density exceeding 10$^{-6}$ in optical traps, but with rather small molecular numbers. To progress towards quantum degeneracy, a mechanism is needed that combines sub-Doppler cooling and magneto-optical trapping (MOT) to facilitate near unity transfer of ultracold … WebThrough a clever combination of red-detuned, circularly polarized light and magnetic fields, the magneto-optical trap (MOT) slows atoms from their speed at room temperature (around 1000 m/s) to just a few cm/s, all in about a milli-second!

WebJul 15, 2007 · A mirror magneto-optical trap (MOT) that exploits a hexapole-compensated magnetic field was developed and used in the experimental surface trapping of neutral atoms. A pair of subsidiary wires, which was placed near the main current-carrying wire, was designed to improve the uniformity of the quadrupole magnetic field and thus increased … WebApr 3, 2024 · These beams are directed above the chip to intersect at a central location with diameters > 1 mm. Our design also includes two co-propagating beams at lattice and clock wavelengths. These beams emit colinearly and vertically to probe the center of the magneto-optical trap, where they will have diameters of ≈ 100 µm.

Two coils in an anti-Helmholtz configuration are used to generate a weak quadrupolar magnetic field; here, we will consider the coils as being separated along the -axis. In the proximity of the field zero, located halfway between the two coils along the -direction, the field gradient is uniform and the field itself varies linearly with position. For this discussion, consider an atom with ground and excited states with and , respectively, where is the magnitude of the total angular momentum vect… huawei health to stravaWebThe first proposal for a molecular magneto-optical trap (MOT) identified five classes of diatomic molecules as being amenable to laser cooling and trapping [14], includ-ing halides, hydrides, oxides, carbides, and sulfides.
