WebNov 13, 2024 · We experimentally and numerically study the localization transition in the ground state of noninteracting and weakly interacting bosons in an eightfold symmetric quasicrystalline optical lattice. In contrast to typically used real space in situ techniques, we probe the system in momentum space by recording matter wave diffraction patterns.

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.
