2008
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:
- To find an optimal functional using all our knowledge of
the nucleonic Hamiltonian and basic nuclear properties.
- To apply the DFT and its extensions to validate the
functional using the relevant nuclear structure data.
- To
apply the validated theory to properties of interest that cannot be
measured, in particular the transition properties needed for reaction
theory.
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:
- What essential experimental
data should be taken into account for the EDF
optimization ?
- What optimization
techniques should be used ?
The meeting is
meant to be very informal with 2-3 introductory talks followed by a
round-table discussion.
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.
Accomodation
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 14
th 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.
