1:30 PM - CNST ELECTRON PHYSICS GROUP SEMINAR: Optical Nuclear Physics Step 1: Trapping Th3+
The nucleus of the 229-Th isotope is unique in that it possesses a very low energy (7.5 eV) nuclear isomer. It may be possible to someday drive this transition coherently, opening the way for a new kind of optical clocks and more precise measurements of fundamental constants. The Th3+ ion is an ideal candidate for such work because of its simplified level structure and potentially long trap lifetime. I will present the recent progress towards the realization of an optical nuclear frequency standard, namely the trapping and observation of 232-Th3+ ions, by the Chapman and Kuzmich research groups at Georgia Tech.

10:30 AM - PROCESS MEASUREMENTS DIVISION SEMINAR: A Novel Instrumental Approach Combining Simultaneous Morphological and Spectroscopic Measurements: Applications to the Characterization of Complex Materials
A Novel Instrumental Approach Combining Simultaneous Morphological and Spectroscopic Measurements: Applications to the Characterization of Complex Materials In most cases measuring the chemical and physical properties of materials is accomplished by separate analytical methods but there is an increasing recognition that hybrid instrumentation that can measure both these properties simultaneously is extremely valuable, particularly for understanding their inter-relationship, and overall impact on the functionality of finished manufactured products or biological materials. In summary these approaches enable characterization of structure/function relationships. The pharmaceutical industry in particularly sees the benefit of these approaches as the complexity of finished products continues to increase and the mechanisms that drive product performance becomes less well understood. We will present data derived from a hybrid analytical technology that combines spectroscopic data with morphological information to derive improved measurement efficiency, and new insight into complex manufactured products and biological materials. In addition, data analysis methods that attempt to seamlessly integrate and correlate chemical, physical and morphological heterogeneity to determine their impact on product performance will be discussed.

10:30 AM - CNST ELECTRON PHYSICS GROUP SEMINAR: ELECTRON DIFFRACTION AND INTERFEROMETRY WITH NANO-GRATINGS
We used nano-manufactured gratings to diffract and interfere low energy (0.3-5keV) electron matter waves. This demonstrates that nanostructures can be used for coherent electron optics, despite the keen sensitivity of low energy electrons to weak electromagnetic interactions. We use this sensitivity to probe the self-induced 'image charge' potential between moving electrons and the surfaces of the grating, which are less than 25nm away. We have observed several interference phenomena using electron beams with very different spatial coherence properties, and we have developed a theoretical framework based on Gaussian Schell-model beams that can efficiently model all types of interferometers that use diffraction gratings and partially coherent beams. I will discuss these experiments, their simulations, and the custom microscope we built for the research. I will also present ideas for future research directions afforded by electron interferometry.

10:30 AM - ITL SEMINAR SERIES: Tagging Video for Geo-referenced Search
More and more video clips are being collected and stored using various devices for many purposes such as surveillance, monitoring, filming, reporting, and, of course, just for fun. Some types of video data naturally tie with their locations and trajectories in geographic space-time. For example, video data for air surveillance or monitoring may not have any meaning without its space-time coordinated locations or trajectories. Combining video data and its trajectories in geographic space-time shall open up a new domain of video applications, requiring an efficient way of indexing and searching a scalable amount of video data in the geo-reference frame of motion. One challenging aspect of this research is how to tag the collected geo-reference data (i.e., GPS or trajectory and compass directions) to video. Considering various types of video standards and collecting devices, a standard for the trajectory metadata and a standard way of tagging the metadata pose an important research challenge. This is even more complicated when we consider video editing. This research will investigate on the standardization of embedding geo-reference data into video standards such as MPEG at varying granularity levels of video (frame, scene, segment, and clip level).

10:30 AM - NIST COLLOQUIUM SERIES: Digital Forensics
Photography lost its innocence many years ago. Shortly after the first commercially available camera was introduced, photographs were being manipulated and altered. With the advent of digital cameras, powerful personal computers, and sophisticated photo-editing software, the manipulation of digital images is becoming much more common. We are seeing the impact of these technologies in nearly every corner of our lives. I will describe computational techniques that we have developed to detect tampering in digital media. Operating in the absence of digital watermarks or signatures, these techniques detect statistical correlations that result from specific forms of digital tampering.

10/20/08 10:30 AM - NANOFABRICATION RESEARCH GROUP SEMINAR: In-situ Studies of Nanoscale Phenomena: Are the Challenges Worth Taking?
High-resolution microscopy is more of a necessity than luxury in investigating nanoscale materials. In this talk, we elucidate this by discussing in-situ SEM/TEM (scanning/transmission electron microscopy) testing of mechanical behavior of materials. This approach provides unprecedented experimental capabilities such as simultaneously quantitative (strain-strain) and qualitative (deformation, dislocation, crack visualization) materials characterization, with the added benefit of monitoring 'cleanliness' of the experiments. Unfortunately, these environments (for example, the TEM) have serious space restrictions and pose challenges with equal proportion because of the drastic miniaturization required for the lab-on-a-chip type capabilities. We address the challenges using nanofabrication techniques and discuss several examples of micro/nanotechnology enabled experimental setups. While the focus of this talk remains on mechanical testing of nanoscale thin films or one dimensional materials, we present some new directions for the research in nanoscale materials for pressing applications such as energy conversion, sensors and actuators and micro-electronic devices. Particularly, we visit the multi-domain (thermal, electrical, mechanical etc) coupling phenomena, which can be predicted to be stronger than what we observe at the macro or even micro scales. An ongoing research on experimental multi-physics lab-on-a-chip will be presented.

10/30/08 10:30 AM - METALLURGY DIVISION SEMINAR: Magnetization Behavior in Exchange-Biased Patterned Nanostructures
Magnetization processes in patterned magnetic heterostructures are of fundamental scientific interest and have important applications in information storage such as in non-volatile magnetoresistive random access memories (MRAM). Continuous miniaturization causes materials defects to play an increasingly important role in the magnetization switching behavior of these devices. Transmission electron microscopy (TEM) is the technique of choice for high spatial resolution characterization of non-ideal magnetic behavior and its relationship with nanoscale structure. In combination with novel phase retrieval techniques, Lorentz TEM has the potential of becoming an in situ quantitative technique for mapping magnetization reversal processes. We have used a combination of Lorentz TEM, magneto-optical Kerr magnetometry and micromagnetic simulations to characterize the behavior of micron-size exchange-biased magnetic nanostructures exhibiting vortex magnetization and imprinted with circular exchange bias. Circular exchange bias promotes a reversible vortex behavior and it controls the chirality of the vortex during reversal. It also stabilizes the vortex structure as a low energy state, acting against magnetocrystalline anisotropy which favors the formation of domain walls. Exchange bias suppresses stochastic processes due to thermal activation and cause the magnetization reversal to be reproducible over time, an important feature in applications. Phase imaging based on the Transport–of-Intensity Equation (TIE) is emerging as a novel method for mapping magnetization phenomena in situ in the TEM. The phase shift of the electrons containing the magnetic information is obtained from the intensity of the wave and its derivative along the optical axis alone, and does not require a reference beam as conventional interferometry techniques do. Examples of application of TIE to patterned magnetic heterostructures will be shown and the requirements for becoming a quantitative technique as well as its limitations will be described. TIE-based phase retrieval has potential applications in novel systems such as multilayered magnetic and multiferroic heterostructures for data storage and logic applications. Furthermore, TIE is not limited to magnetic systems, as it offers opportunities in mapping electric fields and charge transport processes at the nanoscale.

10/31/08 10:30 AM - NIST COLLOQUIUM SERIES: What are the Laws of Physics?
For 300 years the orthodox view of the laws of physics is that they are immutable, universal, infinitely-precise mathematical relationships that were somehow imprinted on the universe at its birth. The hidden assumptions that underpin this view can be traced to cultural factors at the time that physics was first formulated as a discipline. In recent years, some have begun to question these assumptions. In my talk I shall focus on the infinitely-precise quality, arguing that it is an unjustified extrapolation, especially in cosmological models that place a fundamental information bound on the observable universe. The existence of such a bound forces us to confront the nature of the laws of physics in certain experimentally-realizable situations, e.g., entangled states of more than 400 particles. Paul Davies is a prolific author of popularized science books. Some of his more recent books will be available for review and purchase before and after the lecture.

10/31/08 1:30 PM - PHYSICS LABORATORY COLLOQUIUM: Quantum Weak Measurements: A Generalization of the Exponential Decay Law
Quantum mechanical measurements are normally discussed in terms of projective von Neumann-type irreversible processes, but recently a new class of measurements has been proposed and experimentally tested. These are weak measurements carried out on identically-prepared ensembles. Weak measurements offer a new opportunity to test quantum mechanics when they are augmented with post-selection, i.e., retaining the measurement results for only sub-ensembles that satisfy a specified final condition. This generalization, which has been developed by Yakir Aharonov and his co-workers, remains within the framework of conventional quantum mechanics, yet permits interesting generalizations. I will consider how the familiar exponential decay law of unstable quantum systems is merely the strong measurement limit of a broader class of "decay laws" that permit the observer to select a sub-ensemble of systems that have decayed by a specified final time. I derive the generalized decay law, which is open to experimental test.
