Atomic Physics in Ion Traps

March 1, 1997
Author(s)
C Monroe, John Bollinger
Ion traps allow researchers to control the position and movement of charged particles with exquisite precision, and provide a powerful way to study many atomic phenomena.

Optimal Frequency Measurements with Maximally Correlated States

December 1, 1996
Author(s)
John J. Bollinger, Wayne M. Itano, David J. Wineland, D J. Heinzen
We show how maximally correlated states of N two-level particles can be used in spectroscopy to yield a frequency uncertainty equal to (NT)-1, where T is the time of a single measurement. From the time-energy uncertainty relation we show that this is the

Nanofabrication of a Two-Dimensional Array Using Laser-Focused Atomic Deposition

September 4, 1995
Author(s)
R Gupta, Jabez J. McClelland, Zeina J. Kubarych, Robert Celotta
Fabrication of a two-dimensional array of nanometer-scale chromium features on a silicon substrate by laser-focused atomic deposition is described. Features 13plus or minus}1 nm high and having a full-width at half maximum of 80plus or minus}10 nm are
