  • Jacobs, Kurt; Wang, Xiaoting; Wiseman, Howard M. (IOP Publishing, 2014-07)
    We show that when the speed of control is bounded, there is a widely applicable minimal-time control problem for which a coherent feedback protocol is optimal, and is faster than all measurement-based feedback protocols, ...
  • Ammari, Habib; Bretin, Elie; Garner, Josselin; Jugnon, Vincent (Society for Industrial and Applied Mathematics, 2012-09)
    The aim of this paper is to develop new coherent interferometry (CINT) algorithms to correct the effect of an unknown cluttered sound speed (random fluctuations around a known constant) on photoacoustic images. By ...
  • Hostetler, John L.; Miester, Carl; Dorsch, Friedhelm; Huang, Robin K.; Chann, Bien; Missaggia, Leo J.; Augst, Steven J.; Connors, Michael K.; Turner, George W.; Sanchez-Rubio, Antonio; Donnelly, Joseph P. (Institute of Electrical and Electronics Engineers, 2009-08)
    We have coherently combined up to 7.2 W CW using an individually addressable 10-element-array of 960-nm slab-coupled optical waveguide lasers (SCOWLs). We are currently scaling the phase-locked output power to 100 W using ...
  • Bulovic, Vladimir; Tischler, Jonathan R.; Young, Elizabeth Renee; Nocera, Daniel G. (Institute of Electrical and Electronics Engineers, 2009-08)
    Lowest reported threshold organic semiconductor VCSEL (4.9 muJ/cm[superscript 2]) is achieved when excitons coherently couple, upon sub-picosecond non-resonant optical excitation. Temperature dependence of lambda/2 n device, ...
  • Jao, Jen King (Institute of Electrical and Electronics Engineers, 2006-05)
    This paper analyzes the target geolocation performance of coherent processing of target signals observed by several radar receivers in a multilateral configuration. Each radar sensor is designed with a sufficient bandwidth ...
  • Anderson, Alexander John; Conrad, Janet; Figueroa-Feliciano, Enectali; Scholberg, K.; Spitz, J. (American Physical Society, 2011-07)
    Coherent elastic neutrino-nucleus and weakly interacting massive particle-nucleus interaction signatures are expected to be quite similar. This paper discusses how a next-generation ton-scale dark matter detector could ...
  • Lee, Andrew Lee; Chan, Vincent W. S. (Institute of Electrical and Electronics Engineers, 2010-03)
    Optical communication through the atmosphere has the potential to provide data transmission over a distance of 1 to 100 km at very high rates. The deleterious effects of turbulence can severely limit the utility of such a ...
  • Suleiman, Riad S. (American Physical Society, 2011-03)
    We have measured the differential cross section for the γ3He→π+t [y superscript 3 He → pi superscript + t] reaction. This reaction was studied using the Continuous Electron Beam Accelerator Facility (CEBAF) Large Acceptance ...
  • Kinast, Joseph M.; Radojevic, Antonije M.; Timmons, Brian P.; Stoner, Richard E.; Butts, David L.; Kotru, Krish (American Physical Society (APS), 2011-10)
    Raman pulse atom interferometry is an important modality for precision measurements of inertial forces and tests of fundamental physics. Typical Raman atom optics use two coherent laser fields applied at gigahertz-scale ...
  • Zhong, Xinxin; Zhao, Yi; Cao, Jianshu (Institute of Physics Publishing and Deutsche Physikalische Gesellschaft, 2014-04)
    The time-dependent wavepacket diffusion method for carrier quantum dynamics (Zhong and Zhao 2013 J. Chem. Phys. 138 014111), a truncated version of the stochastic Schrödinger equation/wavefunction approach that approximately ...
  • Khasin, Michael; Cao, Jianshu; Moix, Jeremy (IOP Publishing, 2013-08)
    Excitonic transport in static-disordered one dimensional systems is studied in the presence of thermal fluctuations that are described by the Haken–Strobl–Reineker model. For short times, non-diffusive behavior is observed ...
  • Iyer, Deepak; Mondaini, Rubem; Will, Sebastian; Rigol, Marcos (American Physical Society, 2014-09)
    Recently, it has been shown that the momentum distribution of a metallic state of fermionic atoms in a lattice Fermi-Bose mixture exhibits coherent oscillations after a global quench that suppresses tunneling. The oscillation ...
  • Sanders, Scott N.; Mintert, Florian; Heller, Eric J. (American Physical Society, 2009-02)
    We investigate decoherence in atom interferometry due to scattering from a background gas and show that the supposition that residual coherence is due to near-forward scattering is incorrect. In fact, the coherent part is ...
  • Cappellaro, Paola; Viola, Lorenza; Ramanathan, Chandrasekhar (American Physical Society, 2011-03)
    Spin chains have been proposed as quantum wires in many quantum-information processing architectures. Coherent transmission of quantum information in spin chains over short distances is enabled by their internal dynamics, ...
  • Baiz, Carlos; Peng, Chunte; Reppert, Michael Earl; Jones, Kevin C.; Tokmakoff, Andrei (Royal Society of Chemistry, 2012-03)
    We present a method to quantitatively determine the secondary structure composition of globular proteins using coherent two-dimensional infrared (2DIR) spectroscopy of backbone amide I vibrations (1550–1720 cm−1). Sixteen ...
  • Turner, Daniel B.; Wen, Patrick; Arias, Dylan H.; Nelson, Keith Adam (American Physical Society (APS), 2011-10)
    We use fifth-order two-dimensional electronic spectroscopy to measure coherent four-particle dynamics in a semiconductor nanostructure. By using optical polarization control in two-quantum measurements enabled by the COLBERT ...
  • Sabatini, Silvia; Zara, Catalin; Guillemin, Victor W. (Springer-Verlag, 2011-05)
    The equivariant cohomology ring of a GKM manifold is isomorphic to the cohomology ring of its GKM graph. In this paper we explore the implications of this fact for equivariant fiber bundles for which the total space and ...
  • Tang, Jing; Trahan, Daniel W.; Doyle, Patrick S. (American Chemical Society, 2010-02)
    We experimentally investigate the influence of slitlike confinement on the coil−stretch transition of single DNA molecules in a homogeneous planar elongational electric field. We observe a more gradual coil−stretch transition ...
  • Osorio, Carlos A.; Dori, Dov; Sussman, Joseph M. (John Wiley & Sons, Inc., 2011-04)
    There is growing evidence for the relevance of human behavioral factors in successful development of new products, processes, and services. The evidence is even clearer when the forces affecting the development and evolution ...
  • McDonald, Michael A.; Wei, Lisa H.; Veilleux, Sylvain (Institute of Physics/American Astronomical Society, 2012-08)
    We present the results of interferometric observations of the cool core of A1795 at CO(1-0) using the Combined Array for Research in Millimeter-wave Astronomy. In agreement with previous work, we detect a significant amount ...
