WebMar 7, 2024 · The successful throw-and-catch of single atom was recorded to be 94(3)% probability in experiments carried out with 35200(2700) m/s^2 acceleration. For the experiment, we used rubidium cold atoms [1]. The optical tweezers are first switched on to capture atoms in a magneto-optical trap, and then controlled to be accelerated, switched … WebMar 28, 2024 · The research team accelerated the laser of an optical tweezer to give an optical kick to an atom to send it to a target, then caught the flying atom with another optical tweezer to stop it. The atom flew at a speed of 65 cm/s, and traveled up to 4.2 μm.
WebOptical tweezers are tools for manipulating small items using light . As early as 1970, it was demonstrated that laser beams can be used to trap and move small particles, e.g. micron-sized latex spheres in water. This is possible due to various kinds of light forces . WebThe trap stiffness us the key property in using optical tweezers as a force transducer. Force reconstruction via maximum-likelihood-estimator analysis (FORMA) determines the optical trap stiffness based on estimation of the particle velocity from statistical trajectories. Using a modification of this technique, we determine the trap stiffness for a two micron particle …
