Webcreation of an optical lattice formed by two parallel beams brought together at the focal plane of a lens. We use a novel method to change the distance between the two beams … WebThe actual technical implementation of conventional interferometers is quite complex and requires manual manufacturing. In combination with the required construction space defined by the optical setup, their applications are limited to selected measuring tasks. In contrast, Standing Wave Interferometers (SWIs) offer an enormous potential for …

Among their many uses, laser beams can trap matter such as atoms and molecules. Two or more intersecting laser beams can combine and “interfere” to form a standing wave, an array of peaks and valleys of light intensity. Depending on the number and arrangement of the laser beams, the standing wave can extend in … See more Soviet physicist Vladilen Letokhov introduced the idea(link is external)of optical lattices more than a half century ago, in the 1960s. Researchers began to create such light traps … See more Clocks using atoms trapped in an optical lattice, rather than the historical approach of using a “cloud” of unconfined neutral atoms, dramatically reduce the influence of atomic motion on the clock’s ticking. Hidetoshi Katori of … See more Parallel with the development of lattice clocks, NIST researchers since the 2000s have explored the use of atoms in optical lattices to perform … See more Ana Maria Rey, a NIST physicist at JILA, has contributed important theoretical work, including models that have helped to improve clock performance by identifying and explaining quantum interactions between multiple … See more WebThe paper focuses on the optical lattices that are formed by evanescent standing waves, instead of running waves of the medium.
