Dr. Yehuda Braiman is a Research Professor at CREOL, The College of Optics and Photonics, and for the Department of Electrical and Computer Engineering at the University of Central Florida.
Dr. Braiman’s research interests cover multiple disciplines including lasers and optics, dynamics of Josephson junctions and Josephson junction arrays, nonlinear dynamics and chaos control, friction and fracture at the atomistic scale, and detection of weak signals in noisy environment. Specific applications include beam combining and phase-locking of high-power semiconductor diode arrays, studying the dynamics and formation of ultrafast pulses in semiconductor diodes, design of cryogenic memory based on small arrays of Josephson junctions, and studying effects of very weak perturbations on noisy extended nonlinear systems. He co-authored over 100 journal and conference papers, 8 book chapters, edited one book, and co-authored 5 patents. Some of Dr. Braiman’s major research accomplishments include (1) discovery of chaos in Josephson junctions (with E. Ben Jacob and Y. Imry); (2) devised a method to control chaos (with I. Goldhirsch, Physical Review Letters article cited more close to 625 times according to Google Scholar); (3) first author on pioneering papers suggested that spatial heterogeneities in system parameters can induce and promote synchronization in complex nonlinear systems. Article highlighted on cover page of Nature and in Nature News & Views, (“Taming Spatiotemporal Chaos with Disorder”, with W. L. Ditto and J. F. Lindner, article cited more than 275 times according to Google Scholar). Additional article “Disorder Induced Synchronization” in Physics Letters A was cited more than 100 times, and (4) Proposed design for ultrafast and energy efficient cryogenic memory cell. The article was published in Superconductor Science & Technology and was selected for the Superconductor Science and Technology 2016 Highlight Collection.
