Physics Colloquium, Fri., Oct. 4, PSB 161


 Prof. Inna Ponomareva

    Department of Physics, University of South Florida

          Complex ferroics such as ferroelectrics, ferroelastics, magnetoelectrics, antiferroelectrics, and others are associated with rich physics and a variety of technological   applications.  In the recent years such materials attracted even more attention, thanks to the discoveries of ferroelectricity at the nanoscale, magnetoelectric coupling in multiferroics and  giant caloric effects in some ferroics.  Interestingly, theoretical and computational research played an important,  and sometimes even leading, role in the recent progress in fundamental understanding of such novel phenomena associated with complex ferroics. I will highlight some of our most recent advances in the area of predictive modeling of such materials. In particular, I will briefly review some of our recent methodological developments and then focus on the computational discoveries of giant electrocaloric, piezocaloric and multicaloric effects in ferroelectrics.  I will also present some of our recent findings on the unusual dynamics associated with ferroelectric nanostructures and its potential applications for THz sensing.

Inna Ponomareva received M.S. Degree from Volgograd State University, Russia in 2001, and the Ph.D. degree in physics from Institute of Biochemical Physics of Russian Academy of Sciences in 2004. In 2004 she joined University of Arkansas as a postdoctoral fellow. She joined the department of Physics at the University of South Florida in 2009 as an assistant professor. She is a NSF CAREER awardee. Her research is funded by the U.S. Department of Energy,  National Science Foundation and the Army Research Office of the Department of Defense.  She has co-authored over 50 journal publications.

Cosmochemical Evidence for Astrophysical Processes in the Early Solar System

            Isotopic and other studies of primitive material left over from the birth of the Solar system, such as chondrite meteorites and captured comet dust, provide evidence for the conditions, processes, and even timing of processes that occurred during the first ~ 1 m.y. of the solar system’s existence. The Sun likely was born in a giant molecular cloud similar to Orion and Carina, and its birth may have been immediately preceded by a nearby supernova. There also is good evidence that our Sun experienced bi-polar outflow during its infancy, a process that resulted in innermost-solar-system solid materials being ejected out to at least the asteroid belt and possibly as far as the comet accretion regions.

Florida Space Institute Seminar September 18

Florida Space Institute Seminar Announcement

Speaker:  John Wise
Affiliation: Air Force Research Lab, Space Weather Center of Excellence Branch of the Battlespace Environment Lab of the Space Vehicles Directorate
Day and Date: Wednesday, September 18, 2013

Title:          Empirical Modeling Of The Thermosphere
The thermosphere is the part of our atmosphere extending from 80 km to around 600 km.  It is the region in which low earth orbit (LEO) satellites operate.  Neutral density variations from the thermosphere create drag on these satellites and affect their orbits.  In order to understand how the thermosphere affects satellite orbits we need  to model its neutral density and composition.  We discuss some measurements from  the Atmospheric Density Mass Spectrometer (ADMS), which flew onboard the TacSat-2 satellite during the last solar minimum in 2007, which collected  in-situ ratios of total oxygen/N2  in the thermosphere between 415-425 km, at various local times and latitudes equatorward of +/- 40 degrees.   The number densities for oxygen and nitrogen were compared to the NRLMSISE-00 model and to the mass spectrometer measurements of the OSS and NATE from Atmospheric Explorer (AE) during the solar minimum of 1976.  The ADMS atomic oxygen was determined to be more than 50% lower than the atomic oxygen measured by AE at 400 km.  During 2007 the atomic oxygen was about 50% lower than MSIS, but the ADMS N2 densities were in reasonable agreement with the model.  ADMS did not collect data for helium so we are only able to infer its mixing ratio based on corrected model results.  We adjusted  the MSIS total density and O/N2 profiles for several local times when ADMS, CHAMP and GRACE were co-located.  The MSIS exospheric temperature  and atomic oxygen were adjusted to reduce data/model errors between the three experiments in a least squares sense.  Reasonable fits were obtained for late afternoon in the northern hemisphere as well as midnight local times, but the dawn and noontime cases were more difficult to model.

In this talk, we shall consider generalizations of the work of Bender and co-workers to derive new partially-integrable hierarchies of various PT -symmetric, nonlinear partial differential equations. The possible integrable members are identified employing the Painleve Test, a necessary but not sufficient integrability condition, and are indexed by the integer n, corresponding to the negative of the order of the dominant pole in the singular part of the Painleve expansion for the solution. For the PT -symmetric Korteweg-de Vries (KdV) family, as with some other hierarchies, the first or n = 1 equation fails the test, the n = 2 member corresponds to the regular KdV equation, while the remainder form an entirely new, possibly integrable, hierarchy. Typical integrability properties of the n = 3 and n = 4 members, including Backlund Transformations, a 'near-Lax Pair', and analytic solutions are derived. The solutions prove to be algebraic in form, and the extended homogeneous balance technique appears to be the most efficient in exposing the near-Lax Pair. If time permits, analogous results will be discussed for the PT symmetric (2+1) Burgers' and Kadomtsev-Petviashvili equations.

Research Finds Florida SBDCs Continue to Have Substantial Impact on State's Economy

Media Release

Release Date: September 10, 2013

Research Finds Florida SBDCs Continue to Have
Substantial Impact on State's Economy
47,845 jobs created, retained & saved at a cost of $112 per job
FSBDCN State Office: Fostering entrepreneurship and growing small businesses are the foundation for job creation and our state's economic vitality. As one of Florida's most important economic contributors, small businesses employ over 42 percent of the Florida's workforce and represent 98 percent of the state's firms. New research on small businesses in Florida validates this claim.

According to an independent study conducted by the Haas Center, Economic Impact of the Florida SBDC Business Development Activities on the Florida Economy 2013, the Florida SBDC Network program helped entrepreneurs create, retain and save a total of 47,845 direct and indirect jobs across the state at a significantly low cost of $112 per job to the Florida taxpayer.

"The SBDC's minimal per-job cost to the Florida taxpayer represents a significant departure from norm in an era when states and regions typically compete through their economic development organizations for jobs that cost the taxpayers several thousand dollars each," said Dr. Rod Lewis, Director of the Haas Center. "The Florida SBDC Network provides invaluable services to small businesses across the state of Florida."

These growing businesses increased sales by $6.3 billion, generated $215 million in state tax revenue, and contributed $3.9 billion to the state's economy as a result of the work of the Florida SBDC Network.

"The return on investment in the FSBDC program is substantial. For every $1 invested in the program, $40 is returned to the state in tax revenue," said Michael Myhre, State Director (Interim) of the Florida SBDC Network. "These results point to the importance of small businesses having access to the management and technical assistance they need to make sound business decisions."

The research also found that small businesses assisted by the FSBDCs are growing at a much faster rate than the average Florida firm, and that the FSBDC helps create high-skill, high-wage jobs in the state. Established manufacturing firms, for example, that received business consulting from the FSBDC saw a job growth of 9.2% compared to 1.7% growth for the average Florida manufacturing firm.

As the state-designated principal provider of small business assistance, the Florida SBDC Network serves the complex and diverse needs of entrepreneurs and businesses through no-cost professional consulting, value-added business training, and access to business data and information. Since its inception, the FSBDCs have served over 1.1 million entrepreneurs and small business owners and is the only statewide organization capable of providing business assistance through all stages of their business growth.
About the FSBDC Network

For over 35 years, the FSBDC Network has nourished a statewide partnership between higher education and economic development organizations, dedicated to providing emerging and established business owners with management and technical assistance, enabling overall growth and increased profitability for the businesses and economic prosperity for the state. A statewide service network of 41 centers with 60 outreach locations, the FSBDC Network is funded in part through a cooperative agreement with the U.S. Small Business Administration, hosted by the University of West Florida and accredited through the national Association of SBDCs. To learn more about the FSBDC Network or to find a SBDC near you, visit or call 1.866.737.7232.

In 2012, the Florida SBDCs served approximately 38,000 entrepreneurs and small business owners through consulting and training, resulting in 47,845 jobs created, retained and saved; $6.3 billion in sales growth; $235.2 million in capital accessed; $588.4 million in government contract awards; and 744 new businesses started.

Physics Colloquium - Dr. Michael Sigman, UCF, Fri., Sept. 6, 4:30, PSB 161

Tracking the Terrorists: Forensic Analysis of Explosives
Michael Sigman
Professor, Chemistry
Director, National Center for Forensic Science

Forensic analysis of post blast debris is complicated by the destructive nature of explosives.  The isomeric composition and presence of synthetic by-products can be important keys in identifying the possible origin of the material. Industrial and military explosives are often easier to identify than homemade explosives, and the homemade peroxide explosives are more difficult to study since they are not commercially available. This presentation will focus on research at the National Center for Forensic Science in the analysis of commercial explosives and peroxide explosives triacetone triperoxide (TATP), methyl ethyl ketone peroxide (MEKP) and hexamethylene triperoxide diamine.  These peroxide explosive are popular with terrorists.
