Five "Focused Sessions on Cuprates and
Electronic Structure Methods" got the 48th
Sanibel Symposium off to an intense start.
Fourteen invited speakers presented
Aspects of strongly correlated systems and
methods for treating them. There was strong
inter-specialty discussion with participants
expert in quantum chemistry methods and
applications. These sessions were organized
by Professors Hai-Ping Cheng and Peter
Hirschfeld.

Peta-scale computers present great challenges as well
as opportunities to treat more realistically sized
systems, so there was a Workshop on Parallelization of
Coupled-Cluster Methods. These are the most
sophisticated many-body methods in quantum
chemistry. This was organized by Professor Rod
Bartlett. This thematic emphasis within the Symposium
continues a pattern begun last year. Materials and
chemical physics problems are the major theme in
even-numbered years, biomolecular and
pharmaceutical problems in odd-numbered years.
Other threads this year included two thematic sessions
on Optical Properties at Surfaces, and sessions on
Theoretical and Computational Methods, Complex
Spectra, and Metals in Biology.


This was the fourth meeting at the King and Prince
Hotel on St. Simons Island, Georgia, February 21-26.
The similarity of the St. Simons beach-front location to
the original site continues to be popular with
participants. (The meeting left Sanibel Island after the
hotel was sold and razed in 1977.) Attendance remains
strong, though representation from Latin America was
off, apparently because of the cost and hassle of
obtaining visas.

The Cuprates Theme was supported by the U.S.
Department of Energy, Oak Ridge National Laboratory,
the National High Magnetic Field Laboratory, UF's
Center for Condensed Matter Sciences, and the
Department of Physics. The Coupled-Cluster Work-
shop was supported by the U.S. National Science
Foundation and the Department of Energy. General
support was received from the Office of Naval
Research, Taylor and Francis Publishers, John Wiley
and Son, and UF's Office for Research and Graduate
Programs.

The 49th Symposium will take place beginning on
Thursday, February 19, and end at noon on Tuesday,
February 24, 2009. Detailed information on the
program and arrangements will be at
http://www.qtp.ufl.edu/sanibel.

20'8 Summtner Le'cture series
The Preparation and Characterization of (Real) Materials for
Research a University of Florida Perspective These lectures will
introduce students to both various methods of how to prepare samples
(including examples from each lab in the Physics department plus an
overview of the work on campus) and how to characterize their samples
and some of the tricks/pitfalls/opportunities of these methods. The
lectures will also provide the faculty attending with an overview of what
their colleagues are doing and a review of a broad range of
characterization methods, with a focus on those done in-house and at
the Major Analysis Instrumentation Center in the materials science
department. The 75 minute lectures will begin July 21, 2008 and will be
given by Professor Greg Stewart. For more information on the
lectures please visit http://www.phys.ufl.edu/ccms/lecture.

JOINT MATHEMATICS IFT
COLLOQUIUM Professor Bert Kostant (MIT)
will be speaking on "Some of the mathematics in
Garrett Lisi's E(8) Theory of Everything" Monday,
March 17, at 4:00pm in LIT 339. Refreshments will
be served at 3:30pm. A physicist, Garrett Lisi, has published a highly
controversial, but fascinating, paper purporting to go beyond the
standard model in that it unifies all four forces of nature by using as
gauge group the exceptional Lie group E(8). My talk, strictly
mathematical, will be about an elabloration of the mathematics of E(8)
which Lisi relies on to construct his theory.


PHYSICS STUDENTS... First year graduate students,
Rashid Hamdan (Prof Hai-Ping Cheng) and Mohammed Zakaria
(Prof Stephen Hagen) have been selected as recipients of the
CCMS Graduate Fellowship for summer 2008. The fellowship will
provide full financial support including the stipend, tuition, and
insurance.

Ranjani Narayanan has won a graduate student travel award
(from the APS Division of Biological Physics) to attend the March
Meeting in New Orleans.



STAFF NEWS

Congratulations to Darlene Latimer and Bill Malphurs who both
received Division Three 2007-2008 Superior Accomplishment Awards.
They were recognized at the official awards ceremony in February at
Emerson Alumni Hall. According to the award announcement,
"Superior Accomplishment Awards recognize efforts that go the extra
mile beyond your normal assigned duties." Congratulations, Darlene
and Bill!

Unfortunately, Bill Malphurs was unable to attend the award
ceremony due to surgery the same week. Everything went well and Bill
is now recovering. Get well soon!

MICROKELVIN cont'd from page 1 In 1990 with the NSF award to establish a new National Magnet Laboratory in Florida,
it was decided to equip bay three as a specialized high magnetic field --ultra-low temperature facility which today is unique
worldwide and attracts many scientists, including two Nobel prize winners, who wish to conduct experiments at high
magnetic fields and low temperatures simultaneously. The success of the facility has lead the local scientists to extend
operations to include bay 2. In 2007 a state award of 41.3M allowed the facility to place an order for a 20 T magnet to
extend field capabilities, and to place a rapid turn around cooling station (10 Tesla and 10 millikelvin) in the Williamson Hall
Annex that consists of part of the original laboratories of the founding faculty members (Adams, Ihas, Meisel, Sullivan and
Takano) when Physics was housed in Williamson.

John Graham, UF-Physics
Cryogenics Engineer, delivers a 250
liter liquid helium dewar to provide
operating cryostats in the Microkelvin
Laboratory with liquid helium.
Cooling down for the first time can
consume more than 500 liters and
each cryostat boils helium at a rate
of about 20 liters per day --
24/7/360. Annual consumption can
exceed 20,000 liquid liters, depend-
ing on the rate at which experiments are changed.
Fortunately, the department's cryogenic staff, thanks to
helium gas installations designed by Greg Labbe, are able to
recover 95% of the helium and send it to a central liquefier in
the New Physics Building. This service is critical for the
operation of the Microkelvin laboratory and the High B/T
facility, and indeed provides a campus-wide service to
Chemistry, Materials Science, the Physics Williamson Hall
Annex and the McKnight Brain Institute. It is the envy of other
low temperature laboratories around the world.
