Characterization of Atomic Motions Governing Grain Boundary Migration

September 24, 2006
Author(s)
Hao Zhang, David J. Srolovitz, Jack F. Douglas, James A. Warren
Molecular dynamics simulations were employed to study atomic motion within stationary and migrating asymmetric tilt grain boundaries. We employ several measures of the complexity of the atomic trajectories, including the van Hove correlation function, the

Fiber Frequency Combs: Development and Applications

September 19, 2006
Author(s)
Nathan R. Newbury, William C. Swann, Ian R. Coddington, John J. McFerran
The output of a femtosecond fiber laser provides a comb of lines in frequency space that can be phase-locked to either a microwave or optical reference to form a stable frequency comb. We discuss the basic configuration of fiber laser-based frequency combs
