10:30 AM - ELECTRON AND OPTICAL PHYSICS DIVISION SEMINAR: Atomic Structure Calculations and Their Applications: From Parity Nonconservation to Quantum Computing
First-principles atomic structure calculation is a vast subject involving the determination of many different atomic properties: energy levels, transition probabilities, radiative lifetimes, hyperfine constants, static and dynamic polarizabilities, and isotope shifts, among others. I will describe the relativistic all-order method of calculating the "building blocks" needed to determine all of these properties: atomic wave functions. I will show how these wave functions are used to calculate matrix elements to great accuracy and, consequently, determine various atomic properties. Next, I will describe the applications of atomic structure calculations and measurements to topics from different fields of physics such as parity non-conservation: looking for deviation from the Standard Model of the electroweak interactions and nuclear anapole moment; search for electron electric-dipole moment, the question of the variation of the fine-structure constant with time, and quantum computation.

11:00 AM - BIOTECHNOLOGY DIVISION SEMINAR: Electrically Conductive Organic Electrodes for Cardiac Applications: Results with SAM-Au monolayer and organic semiconductor polymer thin film electrodes in vivo
Electrically conductive electrodes with an organic surface have been introduced by our group motivated by the rationale (1) that organic (and organometallic) surface functionalities could modulate tissue response to the implanted electrode and (2) that a platform suitable for surface nanoengineering could change aspects of the electrode tissue interface. In this talk we will review -the characteristics of the in vivo perfused electrode-tissue interface, including the tristable stochastic filtering element that resides there and representations of its equivalent circuit -our results with SAM-Au electrodes, which import a remarkably versatile platform for modification of tissue and electrode electrical response, and allowing for the first time a soluble transfer transfer function for recovery of source signal (due to the reactive equivalent circuit impedance not involving fractional differentiation) -our results with a p-type semiconductor material, allowing an even more tractable transfer function for recovery of source signal.

10:30 AM - OPTICAL TECHNOLOGY DIVISION SEMINAR: Infrared, Raman, and Fluorescence Spectra, Ab Initio Calculations, and Structures of Selected Cyclic Molecules
The vibrational potential energy surfaces of several different cyclic molecules were investigated using far-infrared, Raman, and fluorescence spectroscopies, as well as abinitio calculations. In particular, the far-infrared spectrum resulting from the ring-puckering vibration of 2,3-dihydrofuran (23DHF) was measured. The ring-twisting vibrations of 1,3-cyclohexadiene were interpreted from the vapor-phase Raman and infrared spectra. Laser-induced fluorescence spectra (FES) and dispersed fluorescence (SVLF) spectra of jet-cooled 1,2-dihydronaphthalene were analyzed to investigate ring inversion processes. Ultraviolet absorption, infrared, and Raman spectra were also measured to complement the analyses.

5/21/03 10:30 AM - OPTICAL TECHNOLOGY DIVISION SEMINAR: NEAR-FIELD AND NONLINEAR OPTICAL MICROSCOPY STUDIES OF PHOTOREFRACTIVE POLYMER/LIQUID-CRYSTAL COMPOSITES
Composite thin film materials comprised of polymers and liquid crystals have a number of possible technological applications, including in novel photorefractive devices. Such composites are inherently mesostructured, exhibiting spatial variations in their physical properties on sub-micrometer distance scales. We employ near-field scanning optical microscopy (NSOM) and multiphoton-excited fluorescence microscopy (MPM) to study these materials. NSOM provides high-resolution (sub-100 nm) optical and topographic imaging capabilities for characterization of static sample properties and may also be used to study local dynamical phenomena. MPM provides slightly reduced spatial resolution but is also potentially less “invasive” and allows for depth-resolved imaging in optically thick samples. In a substantial portion of our work, we have been exploring the local optical and electro-optical properties of polymer-dispersed liquid crystals (PDLC). These materials are comprised of micron-sized nematic liquid crystal droplets dispersed in optically transparent polymers. Results of our investigations into liquid crystal droplet shape and overall film morphology will be described. Most notable has been our discovery of "toroidal" liquid crystal droplets. We have also been studying the local dynamics of electric-field-induced liquid crystal reorientation in PDLCs. Dramatic dynamics images depicting spatial variations in the rate and extent of reorientation have been obtained using both NSOM and MPM. These images have provided new information on sub-micron length-scale variations in PDLC properties. Most recently, we have been using NSOM methods to observe changes in the liquid crystal dynamics caused by photogeneration of ions in individual droplets. These studies represent the first time NSOM has been applied to investigations of the photorefractive effect in PDLC materials.

8:30 PM - PHILOSOPHICAL SOCIETY OF WASHINGTON LECTURE: BIOLOGY AND HUMANS IN SPACE
The picture of the whole Earth taken from Apollo 17 spacecraft in December 1972, and the "Pale Blue Dot" image of Earth captured by Voyager I during February 1990 from beyond the orbit of Pluto and Neptune, irreversibly altered our awareness of ourselves and our place in the cosmos. Earth is a beautiful, multi-textured sphere, rich with life, without visible political boundaries, in balance with its surroundings, yet vulnerable in the vastness of space. An increasing number of orbiting platforms have become available in the past two decades that allow us to see and measure aspects of nature that have never been feasible before. Space science generates a constant flow of new ideas and previously unimaginable questions. This presentation will address two intersecting areas of biology and space. Astrobiology is the study of the origin, evolution, distribution, and future of life on Earth and in the Universe. Life in Space is a study of how biology and life react with the space environment and, ultimately, the possibility of humans surviving beyond their planet of origin. How did life begin? Are we alone in the Universe and, if so, what are the philosophical and emotional consequences of this uniqueness? What is the future of humans? What is life and how will it be recognized if encountered away from our home planet? What is the future of humans as spacefarers?

5/29/03 6:30 PM - THE INTIMATE INTEGRATION OF VCSELS WITH VLSI CIRCUITS
Individual and Parallel optical interconnects based on vertical-cavity surface-emitting lasers (VCSELs) are being widely deployed today in switching and routing systems, local area networks, and central offices,and are being designed into future campus and metro applications. One advantage of the VCSEL device that has yet to be fully capitalized upon is its ability, with certain modifications, to be directly connected to electrical circuits at the chip and wafer levels. If properly exercised, this can enable a new dimension of integration of photonics-to-electronics, ushering in a fundamentally lower-cost optoelectronics manufacturing platform and enabling new and perhaps even more pervasive applications of photonics. There now exist manufacturable technologies that can provide chips with 2-D arrays of VCSELS on VLSI circuits. One such photonics-on-VLSI (or Opto-Electronic-VLSI) technology is based on the hybrid flip-chip area-bonding of VCSELs and p-i-n photodetectors and directly to the surface of active silicon VLSI circuits. Other key components that have also attracted a good deal of attention are 2-D array electrical and optical packaging techniques and connectors to support these optoelectronic chips and provide the physical means of transporting and distributing the data "fire-hoses" to and from the OE-VLSI chips. In this presentation, discussions will be given to the status, process, packaging, and performance of OE-VLSI circuits and progress made towards commercializing this technology for high-density optical transceivers and switching products.//Light refreshments, 6:00 p.m., Lecture: 6:30 p.m.//DINNER with speaker OPTIONAL AT COST.
