Steve K. Lamoreaux
Steve K. Lamoreaux received his Ph.D. in atomic physics from the University of Washington in 1986, where he worked until 1996 at which time he moved to Los Alamos National Laboratory. In 2006, he assumed a faculty position in the Department of Physics at Yale. While at the University of Washington, he performed a high precision Casimir force experiment, the result of a series of undergraduate research projects, using a torsion pendulum.
How Casimir forces are shaping up
Modification of electromagnetic zero-point fluctuations by closely spaced conductors causes an interaction between them called the Casimir force. New experiments with nanostructured silicon substrates show that the geometry of the conducting surfaces has a large effect on this force. Read More »
