Today's Colloquium

3:30 p.m.  Meinel 307

 

Photo:  Professor Poul JessenOur 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

 

Photo:  Martin WegenerMartin 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.  CV.

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.
