  • Researchers prove water has multiple liquid states
    on November 19, 2020 at 7:00 pm

    Water is a ubiquitous liquid with many highly unique properties. The way it responds to changes in pressure and temperature can be completely different from other liquids, and these properties are essential to many practical applications and particularly to life as we know it. What causes these anomalies has long been a source of scientific exploration, but now, an international team of researchers that includes Nicolas Giovambattista, a professor at CUNY, has proved that water can exist in two […]

  • Confirming simulated calculations with experiment...
    on November 19, 2020 at 5:28 pm

    Dr. Zi Yang Meng from the Division of Physics and Astronomy, Faculty of Science, the University of Hong Kong (HKU), is pursuing a new paradigm of quantum material research that combines theory, computation and experiment in a coherent manner. Recently, he teamed up with Dr. Wei LI from Beihang University, Professor Yang Qi from Fudan University, Professor Weiqiang YU from Renmin University and Professor Jinsheng Wen from Nanjing University to untangle the puzzle of Nobel Prize-winning theory […]

  • Solving for nuclear structure in light nuclei
    on November 19, 2020 at 3:46 pm

    In nuclei, all the fundamental forces of nature are at play. The dense region at the center of an atom—where the protons and neutrons are found—is a place where scientists can test their understanding of the fundamental interactions of the smallest building blocks of matter in the universe.

  • Surfaces help quantum switches
    on November 19, 2020 at 2:39 pm

    The quantum dynamics of hydrogen are central to many problems in nature, being strongly influenced by the environment in which a reaction takes place. In their contribution to PRL, members of the Lise Meitner Group at the MPSD address hydrogen transfer within a supported molecular switch, showing that the surface support can play a decisive role in the tunneling reaction.

  • A 2-D perspective: Stacking materials to realize...
    on November 19, 2020 at 1:20 pm

    Scientists have designed a 2-D material-based multi-stacked structure comprising tungsten disulfide (WS2) layer sandwiched between hexagonal boron nitride (hBN) layers that displays long-range interaction between successive WS2 layers with potential for reducing circuit design complexity and power consumption.
