Dragomir Davidovic's research focuses on the exploration of physical properties that emerge in objects when their size approaches nanometer-scale. The objects of study are metallic or insulating particles, molecules, atomic-scale diameter wires, and droplets of one phase surrounded by another phase. Recent advances in lithography enable attachment of these objects to larger scale conducting electrodes, making it possible to explore their physical properties by electronic transport. The properties of nanoscale objects can be fundamentally different from those in bulk. As an example, whereas in bulk metals, the energy spectrum of conduction electrons is continuous, in metallic nanoparticles the spectrum is discrete. As a result, metallic nanoparticles are more like atoms than bulk metals, and nanoparticles are commonly referred to as artificial atoms.

    Additional Research:
    High performance computing: ·Development and implementation of novel algorithms to solve partial differential equations in two- and three-dimensional regular and irregular domains. ·Computer modeling of complex systems using supercomputers, as well as graphics cards (GPUs). ·Simulations and large data visualization of complex systems in or near-real time locally or over the web. Experiments in complex systems: ·Cardiac dynamics.Study the voltage and calcium dynamics of cardiac tissue using heart sections or whole hearts from fish and mice to large mamals horses. Using voltage- and calcium-sensitive dyes and ultrafast cameras, we record the dynamics of voltage and calcium waves and study their instabilities associated with arrhythmias. ·Dynamics of spiral and scroll waves. ·Mechanisms of bifurcation and period-doublings in time and in space. ·Methods for chaos control and synchronization. ·Chemical, physical, and other biophysical oscillators with complex dynamics and instabilities. Examples: spiral and scroll waves in the Belousov–Zhabotinsky reaction, saline oscillator. Mathematical modeling of complex systems: ·Development and analysis of mathematical models that describe generic or detailed dynamics of excitable and oscillatory media (heart, neurons, chemical reactions, calcium signaling, physical and biological oscillators, etc.). ·Study of bifurcations and chaotic (organized and disorganized) dynamics of excitable and oscillatory systems. ·Develop and apply control methods for suppressing or synchronizing complex dynamics. ·Study of stability and instabilities of spiral waves and three-dimensional scroll waves in idealized and realistic domains of excitable media. In most projects there is crossover between theory, simulations and experiments, where experiments (simulations) are used to guide theory and simulations (experiments).

    Feryal Ozel is the Chair and Professor in the School of Physics at Georgia Institute of Technology. Her research in astrophysics focuses on theoretical and computational studies of the properties, formation, and environments of black holes and neutron stars. She developed new techniques to determine the properties of neutron star surfaces and interiors. She made predictions of black hole images that guided the development of the Event Horizon Telescope (EHT) and helped constrain physics beyond General Relativity.

     

    Ozel is a founding member of the Event Horizon Telescope collaboration, a former member of the EHT Science Council and lead of the Modeling Working Group. In 2022, she led the announcement of the first image of the black hole at the center of the Milky Way Galaxy. She was co-chair of NASA’s Next Generation Large Mission Concept Study for the Lynx X-ray Observatory and has served for three years as chair of NASA’s Astrophysics Advisory Committee. Prior to joining Georgia Tech, she was a Professor of Astronomy and Physics and the Associate Dean for Research at the University of Arizona

    I have a broad range of interests in soft condensed matter physics and adjacent fields like statistical physics, physics of living systems and hard condensed matter. My particular focus is on the relationship between the geometric structure of a system and its mechanical response. Both biological and engineered systems often have some structure, such as networks of struts, particles jammed together or patterns of creases in thin sheets, that grant them flexibility and strength with a minimum of weight. These structures can lead to subtle and surprising mechanical response:

    The Raman Group has two main thrusts.  The team utilizes sophisticated tools to cool atoms to temperatures less than one millionth of a degree above absolute zero. Using these tools, they explore topics ranging from superfluidity in Bose-Einstein condensates (BECs) to quantum antiferromagnetism in a spinor condensate.  In another effort the team partners with engineers to build cutting edge atomic quantum sensors on-chip that can one day be mass-produced.

    A primary goal of Professor First's research is to develop an understanding of solid-state systems at atomic length scales. The main experimental tools in this pursuit are scanning tunneling microscopy (STM) and related techniques such as ballistic electron emission microscopy (BEEM). These methods rely on the quantum-mechanical tunnel effect to obtain atomically-resolved maps of the electronic structure of surfaces, clusters, and buried layers.
