Today's Colloquium
3:30 p.m. Meinel 307
Our own Poul Jessen will present
Quantum Control of Atomic Spins. Stanley Pau is
the host. Abstract: Laboratory techniques to manipulate and
observe ultracold atoms make these a superb platform on
which to develop and test new ideas in quantum control and
measurement. I will discuss a series of recent experiments
in which we use laser light and magnetic fields to drive
non-trivial quantum dynamics of a large spin-angular
momentum associated with an atomic hyperfine ground state.
The resulting nonlinear spin Hamiltonian is sufficiently
general to achieve universal quantum control over the 2F+1
dimensional state space, and allows us to generate arbitrary
spin states and perform a full quantum state reconstruction
of the result. We have implemented and verified time optimal
controls to generate a broad variety of spin states, as well
as an adiabatic scheme to generate spin-squeezed states for
metrology. Most recently we have used our control and
measurement tools to realize a popular paradigm for quantum
chaos known as the kicked top. Direct observation of the
phase space dynamics of this system has given us an
unprecedented look at quantum/classical correspondence. In
the future we hope to extend our toolbox for control and
measurement of individual atoms and to apply it also to
collective spins. Applications include quantum metrology,
quantum information processing and simulations of quantum
manybody physics.
Friday's OSC Community
Speakers
Noon. Meinel 410
Elka Ertur Koehler, OSC PhD 2000
and MS 1993, will present A Scientist's Perspective of
Congress. Elka Koehler, who served as an AAAS
Congressional Fellow in Washington DC, will present her
experiences and perspectives of the legislative process from
a scientist's point of view. This prestigious
fellowship is designed to demonstrate the value of
science-government interaction, and to bring technical
backgrounds and external perspectives to the decision-making
process in Congress. Working as a special legislative
assistant in policy areas requiring scientific and technical
input gave her the unique opportunity to learn firsthand how
the federal government operates and to help make decisions
that result in national public policy. While serving
as a science advisor to Senator Joseph I. Lieberman (D-CT)
during her leave of absence from Raytheon, she performed
background research for legislation, drafted bills and
amendments, prepared questions for witnesses at Senate
hearings, and wrote Senate floor statements, oversight
letters to the administration, speeches, and position papers
on science and technology related issues. She will
briefly discuss some of the science related issues the
Congress continues to deal with, including the state of the
U.S. innovation infrastructure in the face of globalization.
Boris Glebov, OSC PhD student,
will present Real-Time Observation of Gamma-Ray-Induced
Photodarkening in Laser Crystals. The application
of optical components and devices in space-based systems,
and in other harsh radiation environments, has driven the
need for research to understand the impace of ionizing
radiation on the performance of optical materials.
Yttrium Aluminum Garnet (YAG) is a laser host material with
stable mechanical, optical, and environmental properties.
Common dopants for YAG include both Nd and Cr, appearing as
Nd3+, and Cr4+. In this paper we will discuss the
impact of Y irradiation on the optical properties of doped-YAG
laser materials. Samples with varying composition have
been examined using optical spectroscopy before, during and
after Y irradiation. In contrast with the Cr:YAG,
significant transient radiation-induced photodarkening was
observed in Nd:YAG samples. In essence, we take laser
crystals and blast them with a giant gamma-ray cannon.
We are just down the hall from The Hulk.
Next Week's Colloquium
3:30 p.m. Meinel 307
Martin Wegener, University
Karlsruhe. will present Photonic Metamaterials: Optics
Starts Walking on Two Feet. Galina Khitrova is the
host. Abstract: Metamaterials are man-made
tailored materials composed of sub-wavelength metallic
building blocks ("photonic atoms") that are densely packed
into an effective material. This allows for achieving
optical material properties that simply do not occur in
natural substances. Examples are magnetism at elevated
frequencies, negative refractive indices, giant circular
dichroism, and enhanced optical nonlinearities. Photonic
metamaterials operate at optical frequencies and require
nanofabrication. In this talk, we give an introduction into
this emerging field and review recent progress.

Highlights from Our
Twenty-Ninth Industrial Affiliates Workshop
Brian Miller is Selected to Receive UA's 2008 Student
Technology Innovation Award
The
Student Innovation Award recognizes innovation and
entrepreneurship among University of Arizona students.
The award, given once each year, honors a student who has excelled in a
technology-related internship, independent study, or
research position. His or her work may contribute to the
development, enhancement or commercialization of a new
technology.
Participants at our Industrial Affiliates Workshop
earlier this week may
remember Brian Miller's presentation: CCD-Based Gamma-Ray
Detectors. The award recognizes two separate
invention disclosures called BazookaSPECT and BazookaPet.
BazookaSPECT is a small-animal imaging system which Brian, a
PhD student in Harry Barrett's group, will soon have
licensed for commercialization. Congratulations,
Brian.
Aimee Allen Receives an Award
for her Thesis
Aimee Allen, Research/Laboratory
Assistant to Charlie Falco, has been selected to receive an
Outstanding Thesis Award for her MA thesis titled The
Hockney-Falco Thesis: An Arts-Based Case-Study of
Interdisciplinary Inquiry. The award, presented by
the Arts Based Educational Research Special Interest Group
of the American Educational Research Association, is given
to the scholar whose work is of importance to Arts and
Learning SIG members and
bears the hallmarks of integrity, quality, depth of
knowledge, style and significance to the field.
Amy
was selected as this year's recipient for two reasons:
first, because her thesis reflects the tenets of arts-based
educational research and second, because reviewers were
particularly impressed with her writing and the quality of
her research. Congratulations, Aimee.
