The Primakoff Experiment at
Jefferson Lab (PrimEx)
Participants: A collaborative effort of professional physicists from more than twenty universities and research institutes here and abroad, including UNCW Physics Professor Liping Gan
Description: PrimEx is an experiment to perform a precise measurement of the neutral pion lifetime using the small angle coherent photoproduction of the pi-zero in the Coulomb field of a nucleus, i.e. the Primakoff effect. Precision measurement of the pi-zero radiative decay width is widely recognized as a key finding that bridges chiral symmetry breaking and our understanding of quantum chromodynamics. The results of this experiment will provide fundamental input to the theory of the strong interaction, which has profound significance for our understanding of nature and the structure of matter.
The QMTools Project
Director: Professor Curt Moyer
Description: QMTools is a software development project providing a collection of tools to facillitate the creation of multimedia-enhanced, computer-based classroom materials —worksheets, exercises, tutorials, etc.— for use in teaching introductory quantum physics. Each tool encapsulates a single pedagogical element that can be inserted [as a Java applet] into an HTML document to provide an interactive experience at any point in the presentation. The package is available to the academic community at no charge for non-commercial use. For more information, visit the QMTools home page.
Connectivity and Upwelling Dynamics In the Galápagos Marine Reserve (GMR)
Director: Professor John M.
Participants: A collaborative effort between University of North Carolina Wilmington, North Carolina State University, National Aeronautics and Space Administration (NASA) Goddard Space Flight Center, Charles Darwin Research Station, Galápagos Islands, and Galápagos National Park Service, Ecuador
Quantum Computation and Quantum Information
Participants: In part, this is a collaboration between Moorad Alexanian, Department of Physics and Physical Oceanography, University of North Carolina Wilmington, Wilmington, North Carolina and Subir K. Bose, Department of Physics, University of Central Florida, Orlando, Florida.
Description: Quantum entanglement lies at the
foundation of quantum mechanics as attested by Schr�dinger highlighting
entanglement with his puzzling cat thought experiment and Einstein deriding it
as "spooky action at a distance". Nonetheless, quantum entanglement has been
verified experimentally and is essential for quantum information communication
and processing protocols in quantum cryptography, dense coding, teleportation,
and entanglement swapping, which can be used to realize quantum repeaters.
Entanglement can be achieved via two interacting quantum systems or by an
appropriate joint measurement of two systems. In the development of quantum
algorithms and quantum information processing, one attempts to generate states
that are maximally entangled in order to maximize the advantage of nonclassical
correlations between parts of a given quantum system.
In the study of three-level atoms, a transformation was introduced by us whereby the three-level atom was reduced to a corresponding two-level atom of the Jaynes-Cummings type albeit with two-photon rather than single-photon transitions. This model has been used in cavity quantum electrodynamics (QED) to generate "macroscopic" qubits and in the scattering of two coherent photons inside a one-dimensional coupled-resonator waveguide that operates as an ideal quantum switch. More recently, I have applied the model to two-photon exchange between two separate cavities with each cavity containing a three-level atom in a cascade (or ladder) configuration and coupled via a two-photon hopping interaction. The latter work was restricted to the N = 2 manifold, where N denotes the maximum number of photons possible in a given cavity. I am extending my study to the dynamics of the N = 4 manifold and show how the temporal development of the coupled two-cavity system generates maximally entangled states in both the N = 2 and N = 4 manifolds from an initially unentangled state.
Coastal Ocean Research and Monitoring Program (CORMP)
Director: Professor Marvin
Participants: UNCW Physics Professor Fred Bingham; others from UNCW Departments of Biology, Chemistry, Earth Sciences, and more
Description: Initiated in 1998, this
interdisciplinary program supports efforts by a large number of UNCW
investigators and collaborators from other universities and agencies to study
the physical, geological, chemical and biological properties of the coastal
ocean in the Cape Fear region. Monitoring has focused on larval fish
recruitment, discharge of materials from the Cape Fear River, effects of storm
events on bottom sediments and organisms, physical and chemical signals of water
movements at various scales, biology of marine vertebrate populations, and
analysis of the effects of hurricanes on the coastal ocean. For more
