STICK-SLIP MOTION OF A STRESSED COULOMB CRYSTAL OBSERVED BY NIST SCIENTISTS.(Brief Article)

Journal of Research of the National Institute of Standards and Technology | March 1, 2001 | Copyright

NIST scientists in collaboration with the University of California at San Diego, have recently identified earthquake-like disturbances in what had previously been considered to be stable nonneutral-plasma crystals. Such a crystal, confined in a Penning trap with its rotation locked to a rotating electric field, has potential applications in atomic frequency standards and quantum logic. The value of these crystals lies in their high degree of order and stability, so it is important to learn how to control these unexpected motions.
