Relativistic MHD and black hole excision: Formulation and initial tests
David Neilsen, Eric W Hirschmann, R Steven Millward
A new algorithm for solving the general relativistic MHD equations is described in this paper. We design our scheme to incorporate black hole excision with smooth boundaries, and t…
Electronic transport and localization in short and long DNA
H. Wang, R. Marsh, J. P. Lewis +1
The question of whether DNA conducts electric charges is intriguing to physicists and biologists alike. The suggestion that electron transfer/transport in DNA might be biologically…
Long-Term Stability of an Area-Reversible Atom-Interferometer Sagnac Gyroscope
D. S. Durfee, Y. K. Shaham, M. A. Kasevich
We report on a study of the long-term stability and absolute accuracy of an atom interferometer gyroscope. This study included the implementation of an electro-optical technique to…
The Differential Form Method for Finding Symmetries
B. Kent Harrison
This article reviews the use of differential forms and Lie derivatives to find symmetries of differential equations, as originally presented by Harrison and Estabrook, J. Math. Phy…
Self-referenced prism deflection measurement schemes with microradian precision
Rebecca Olson, Justin Paul, Scott Bergeson +1
We have demonstrated several inexpensive methods which can be used to measure the deflection angles of prisms with microradian precision. The methods are self-referenced, using var…
Increasing the output of a Littman-type laser by use of an intracavity Faraday rotator
Rebecca Merrill, Rebecca Olson, Scott Bergeson +1
We present a new method of external-cavity diode laser grating stabilization which combines the high output power of the Littrow design with the fixed output pointing of the Littma…
