Comprehensive control of atomic motion.

چکیده
Recent work provides a general two-step solution to trapping and cooling of atoms. The first step is magnetic stopping of paramagnetic atoms with the use of a sequence of pulsed fields. The second step is single-photon cooling, which is based on a one-way barrier. This cooling method is related intimately to the historic problem of "Maxwell's Demon" and subsequent work by L. Szilard. Here, I discuss the connections between single-photon cooling and information entropy. I also outline future application of these methods to fundamental tests with hydrogen isotopes.

Dynamics and Motion Control of Wheeled Robotic Systems
Mobile robotic systems, which include a mobile platform with one or more manipulators, mounted at specific locations on the mobile base, are of great interest in a number of applications. In this paper, after thorough kinematic studies on the platform and manipulator motions, a systematic methodology will be presented to obtain the dynamic equations for such systems without violating the base n...

متن کاملReal-Time Control of Atomic Motion Using Feedback
We demonstrate real-time feedback control of atomic center of mass motion in a cloud of laser cooled cesium atoms. Using the velocity measurement technique of recoil-induced resonances, the average velocity of the atomic cloud is obtained. This information is used to give a correction from a moving optical lattice. We are able to bring the cloud of atoms to a stop with a controllable amount of ...

متن کاملSimulations of the Frequency Modulated - Atomic Force Microscope (FM-AFM) Nonlinear Control System
The Frequency Modulated Atomic Force Microscope (FM-AFM) is a powerful tool to perform surface investigation with true atomic resolution. The control system of the FM-AFM must keep constant both the frequency and amplitude of oscillation of the microcantilever during the scanning process of the sample. However, tip and sample interaction forces cause modulations in the microcantilever motion. A...
متن کاملNonlinear coherent dynamics of an atom in an optical lattice
We consider a simple model of lossless interaction between a two-level single atom and a standing-wave single-mode laser field which creates a one-dimensional optical lattice. Internal dynamics of the atom is governed by the laser field which is treated to be classical with a large number of photons. Center-of-mass classical atomic motion is governed by the optical potential and the internal at...
