Latest news

March 21, 2011 Moved the 3FCS server from Liège to Luleå.

October 1, 2009 Fredrik starts a post-doc in bio-inspired computing. 3FCS is now developed by the group of Prof. David Blaschke.

September 14, 2009 Uploaded the python source code for the client-server model used by the on-line GUI.

January 14, 2009 Added a parametrization tool that can be used to fit the (P)NJL parameters to meson properties.

Overview

3FCS is a set of numerical tools that calculates the properties of 3-Flavour Colour Superconducting quark matter. These tools can be used, e.g., to calculate equations of state, phase diagrams, neutrino trapping effects, and effects of colour superconductivity in models of compact stars and heavy-ion collisions. The models implemented in 3FCS have been published in scientific journals and the implementations are numerically effective.

This on-line application is the graphical user interface (GUI) of 3FCS. News and various information about the project are available here also. The GUI presently provides public access to the low-level drivers of 3FCS, which are the C++ programs that perform the calculations. The drivers can be operated from within the GUI (with some limitations on the functionality) or from the command line. The latter requires that you download and compile the source code. The drivers are useful for prototyping and cross checking. Complicated tasks, e.g., calculations of equations of state and phase diagrams are performed by the 3FCS Python interface or an MPI-based code. You are welcome to contact me if you need quark matter tables for a research project.

The GUI uses javascript and follows W3C standards. AJAX is used to load data asynchronously. A javascript menu should appear at the top of the page. If this is not the case, check the javascript setting(s) in your browser. I recommend the Firefox and Opera web browsers. Cookies are used to maintain computing sessions.
