    Narrow Glass Threads Synchronize the Light Emissions of Distant Atoms

    If you holler at someone across your yard, the sound travels on the bustling movement of air molecules. But over long distances your voice needs help to reach its destination—help provided by a telephone or the Internet. Atoms don’t yell, but they can share Read More

    Quantum Simulators Wield Control Over More Than 50 Qubits, Setting New Record

    Two independent teams of scientists, including one from the Joint Quantum Institute, have used more than 50 interacting atomic qubits to mimic magnetic quantum matter, blowing past the complexity of previous demonstrations. The results appear in this week’s issue of Nature. As the basis Read More

    High-altitude Observatory Sheds Light on Origin of Excess Anti-matter

    UMD-led HAWC collaboration suggests dark matter as possible culprit A mountaintop observatory in Mexico, built and operated by an international team of scientists, has captured the first wide-angle view of gamma rays emanating from two rapidly spinning stars. The High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory Read More

    Neutron Star Merger Directly Observed for the First Time

    On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars—the dense, collapsed cores that remain after large stars die in a supernova explosion. The merger is the first cosmological event observed in both gravitational Read More

    Gravitational Waves Detected a Fourth Time

    On August 14, 2017, at 10:30:43 UTC, scientists observed gravitational waves—ripples in the fabric of spacetime—for the fourth time. The twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors—located in Livingston, Louisiana, and Hanford, Washington—detected the gravitational wave event, named GW170814.  Read More

    Turning Ions into Quantum Cats

    In Schrödinger's famous thought experiment, a cat seems to be both dead and alive—an idea that strains credulity. These days, cats still don't act this way, but physicists now regularly create analogues of Schrödinger's cat in the lab by smearing the microscopic quantum world Read More

    Sensing Atoms Caught in Ripples of Light

    Optical fibers are ubiquitous, carrying light wherever it is needed. These glass tunnels are the high-speed railway of information transit, moving data at incredible speeds over tremendous distances. Read More

    Space-based Experiment Will Tackle the Mysteries of Cosmic Rays

    On August 14, 2017, a groundbreaking University of Maryland-designed cosmic ray detector will travel to the International Space Station (ISS) aboard the SpaceX-12 Commercial Resupply Service mission. The instrument, named ISS Cosmic Ray Energetics and Mass (ISS-CREAM), is roughly the size of a refrigerator and Read More

    Simulating the Quantum World with Electron Traps

    Quantum behavior plays a crucial role in novel and emergent material properties, such as superconductivity and magnetism. Unfortunately, it is still impossible to calculate the underlying quantum behavior, let alone fully understand it. Scientists of QuTech, the Kavli Institute of Nanoscience in Delft and Read More

Physics and Astronomy, 1978) has received the 2018 Breakthrough Prize in Fundamental Physics “for detailed maps of the early universe that greatly improved our knowledge of the evolution of the cosmos and the fluctuations that seeded the formation of galaxies.” Read More
  • Dec 1, 2017 Quantum Physics and Gravity Meet in New Assistant Professor's Research Two landmark achievements of 20th century physics remain stubbornly isolated, despite decades of attempts by scientists to bring them together. On their own, they’ve been wildly successful. General relativity—Einstein’s grand theory of gravity—fused space and time into a single entity. It birthed the global positioning Read More
