  • Appearance and Disappearance of Quantum Correlations in Measurement-Based
           Feedback Control of a Mechanical Oscillator

    • Authors: V. Sudhir; D. J. Wilson, R. Schilling, H. Schütz, S. A. Fedorov, A. H. Ghadimi, A. Nunnenkamp, T. J. Kippenberg

      Abstract: Author(s): V. Sudhir, D. J. Wilson, R. Schilling, H. Schütz, S. A. Fedorov, A. H. Ghadimi, A. Nunnenkamp, and T. J. Kippenberg
      One challenge of controlling quantum systems is striking a balance between the random disturbances caused by the act of measurement and stabilizing the system in a desired state. Researchers conduct an experiment in the so-called “quantum feedback regime” in which the disturbance due to a measurement is suppressed.

      Abstract: Author(s): Shijing Tan, Adam Argondizzo, Cong Wang, Xuefeng Cui, and Hrvoje Petek
      When exposed to an ultrafast laser pulse, electrons within graphite are warmed to the same temperature as the surface of the Sun. This behavior could explain how laser light can turn graphite into diamond and allow for efficient chemistry on the surface of graphitic materials.

  • Stochastic and Macroscopic Thermodynamics of Strongly Coupled Systems

    • Authors: Christopher Jarzynski
      First page: 011008
      Abstract: Author(s): Christopher Jarzynski
      Thermodynamics describes how macroscopic systems exchange energy in the form of heat and work, yet many microscopic systems such as molecular motors exhibit behavior that seems to follow the same principles. A new theoretical framework for describing the thermodynamics of microscopic systems that interact strongly with their surroundings is presented.

      Abstract: Author(s): Silvio Bianchi, Filippo Saglimbeni, and Roberto Di Leonardo

    • Authors: Filippo Radicchi; Ginestra Bianconi

      Abstract: Author(s): Filippo Radicchi and Ginestra Bianconi
      When analyzing the robustness of complex, interconnected networks—such as interdependent infrastructures—models often predict that the system becomes more fragile as the number of layers increases. A new model indicates that such multilayered networks can instead be made more robust with the introduction of redundant interdependencies.

      A significant challenge facing quantum computation is noise, and current theory proposes that it is surmountable if it is sufficiently weak and also weakly correlated in space and time. Now, researchers theoretically show that quantum computation can be achieved even when noise with arbitrary time correlations is present.

      Abstract: Author(s): Pablo San-Jose, Vincenzo Parente, Francisco Guinea, Rafael Roldán, and Elsa Prada
      Developing more efficient solar cells has long been a goal of scientists, given the current energy crisis. A theoretical study of black phosphorous, a material useful as an infrared photodetector, shows that it can make a more efficient solar cell in the presence of strain.

      Probing electronic states on ultrafast timescales is critical for studies of chemical reactions. A tabletop method for performing time-resolved x-ray emission spectroscopy is presented and tested using a polypyridyl iron complex.
