Theoretical Physics
Theoretical research in Argonne's Physics Division addresses a broad range of
problems involving the stucture and dynamics of hadrons and nuclei.
There is a strong emphasis on comparison to data provided by experimental
groups at Argonne and at other facilities around the world.
The principal areas of research include:
Several of these projects require major numerical simulations using massively
parallel state-of-the-art computers, including the Argonne LCRC Linux cluster (Jazz), the Argonne MCS Linux cluster (Chiba City) and the NERSC IBM SP (Seaborg). Many projects also
involve collaborators at US and foreign universities, and other national
laboratories.

RIA Related Theory Programs
The Rare Isotope Accelerator
(RIA) project will provide a world-class facility dedicated to the
production and subsequent acceleration of beams of short-lived nuclei.
Argonne's Theory Group is actively involved in numerous projects
relevant to existing exotic-beam research and the future RIA facility,
including:
RIA and Astrophysics

There are many areas of uncertainty in our understanding of crucial
astrophysical phenomena, such as the reliability of type-I supernovae as
standard candles to measure the scale of the universe; the sites of
r-process element production, both type-II supernovae and colliding neutron
stars; and nuclear processes such as breakout from the CNO cycle. Many of
the nuclei that participated in the evolution of our galaxy have never been
made on earth and theories to describe them are not yet quantitatively
reliable. Experimental and theoretical efforts in this direction represent
great challenges and opportunities for nuclear science in coming years.
This programme will focus on these issues.
Forthcoming Activity:
September 12-13, 2003 [Fri. -- Sat. morning]
Surface Compositions of Accreting Neutron Stars
Explosive H-He (rp-process) burning on accreting neutron stars yields
"breakout" from the CNO cycles and subsequent production of proton-rich
nuclei through masses A ~ 100. Detailed multizone models for such events
will be canvassed, along with their implications for X-ray burst light
curves, the composition of the ash, and the evolution of neutron star surfaces.
Organisers:
Ed Brown (UC),
Ken Nollett (ANL),
Craig Roberts (ANL) and
James Truran (UC).
Recent Activity:
August 2003
Nuclear Quantum Monte Carlo Get Together
Practitioners of nuclear quantum Monte Carlo methods (Variational and
Greens Function Monte Carlo) will gather for about two weeks to
discuss recent progress and coordinate new lines of research. Among
the projects to be discussed are
- A benchmark calculation of 12C;
- Calculations of electro-weak transitions in light nuclei; and
- Calculations of scattering processes.
Format: A series of informal seminars and working group meetings focusing on
technical aspects of existing projects, such as those listed, and on
identifying the best means for their improvement and extension.
Recent Activity:
April 28 - May 2, 2003
