The DFT-UNEDF meeting will be held at the Joint Institute for Heavy Ion Research, Bldg. 6025, at Oak Ridge National Laboratory on Tuesday, January 22, 2008. The meeting will be followed by the JUSTIPEN/LACM meeting on January 23-25, 2008.

The Universal Nuclear Energy Density Functional (UNEDF) is a nuclear theory SciDAC project. Its goal is to develop theory of nuclei and their low-energy reactions to a qualitatively new level of accuracy and reliability. It was recognized that the Density Functional Theory (DFT) would be the only possibility to meeting these goals. The mission of the project is:
The aim of the January meeting organized by the UT/ORNL theory group is to prepare the development of the next generation of functionals by discussing various aspects pertaining to the optimization of the EDF. In particular we would like to address the following questions:
The meeting is meant to be very informal with 2-3 introductory talks followed by a round-table discussion.

Practical Information

There is no charge to attend the meeting. If you wish to participate, please do send an email to the JIHIR secretary Sherry Lamb with a copy to Nicolas Schunck and indicate the expected dates of your stay and whether you have any special requirements.

We have a limited budget to support the meals as well as lodging/travel of some participants. Let us know if you need financial support.

Note that on Monday, January 28, R. Furnstahl from Ohio State University will give a physics colloquium at the University of Tennessee at 3:30pm.

A block of 25 rooms has been reserved for the UNEDF and Justipen meetings at the Comfort Inn, Oak Ridge. Rates are $79 per night, continental breakfast included. Guests should make their own reservation by calling 1-865-481-8200 or emailing orcomfortinn@yahoo.com and requesting a room within the block titled JUSTIPEN/DFT-UNEDF. Unused rooms will be released on January 14th to the general public.

Travel information
Knoxville McGhee-Tyson Airport has rather good connections with many major international US airports such as Atlanta, Chicago O'Hare, Detroit, Washington Dulles, etc.

To get from the airport to ORNL: Please note that Tennessee in general, and the Knoxville area in particular, lacks of any kind of public transportation. We strongly advise you to rent a car. The following car rental companies have a desk at Knoxville airport: Avis, Enterprise, Alamo, and Budget.

Important security information
All visitors to Oak Ridge National Laboratory will be required to go to the Visitor Center to obtain their badge for site access. The whole process can take some time, we advise you to arrive early the first day of the meeting so that you have time to complete the procedure.
