Coherent Dynamics of a Single Spin Interacting with an Adjustable Spin Bath
R. Hanson, V. V. Dobrovitski, A. E. Feiguin, O. Gywat, and D. D. Awschalom
Science 18 April 2008: 352-355.
Simulations successfully show how the spin of a nitrogen vacancy in diamond is coupled to those of surrounding nitrogen impurities and how coherence between them is lost.

The ALPS project (Algorithms and Libraries for Physics Simulations) is an open source effort aiming at providing high-end simulation codes for strongly correlated quantum mechanical systems as well as C++ libraries for simplifying the development of such code. ALPS strives to increase software reuse in the physics community.

An application for scientific graphics and data analysis. It features spreadsheets and interactive plots in a user-friendly graphic interface. It has been programmed from scratch using C and the GTK and GtkExtra toolkits. The spreadsheets evaluate expressions in Python, and the plots generate publication quality PostScript output. It has a native file format in XML and it is enhanced under GNOME. The project is open-source and continuously augmented in functionality by many users throughout the world. It is becoming very popular in the scientific community, and it is included in most of the Linux/BSD distributions. Moreover, SciGraphica is being used at places like Siemens, and Nasa (see for instance, the Shuttle Radar Topography Mission at, and for ocean modeling (

A library of widgets for the design of Graphic User Interfaces (GUI). It is cross platform and can be compiled under most flavors of Unix and and Windows. The library is open-source and it is very popular because of its functionality and portability.
