    Quantum particles can be difficult to characterize, and almost impossible to control if they strongly interact with each other — until now.

    An international team of researchers led by Princeton physicist Zahid Hasan has discovered a quantum state of matter that can be “tuned” at will — and it’s 10 times more tuneable than existing theories can explain. This level of manipulability opens enormous possibilities for next-generation nanotechnologies and quantum computing.

  • Surprising hidden order unites prime numbers and crystal-like materials

    The seemingly random digits known as prime numbers are not nearly as scattershot as previously thought. A new analysis by Princeton University researchers has uncovered patterns in primes that are similar to those found in the positions of atoms inside certain crystal-like materials.

  • Higgs particle's favorite 'daughter' comes home

    In a finding that caps years of exploration into the tiny particle known as the Higgs boson, researchers have traced the fifth and most prominent way that the particle decays into other particles. The discovery gives researchers a new pathway by which to study the physical laws that govern the universe.

  • Secretary of Energy Perry says PPPL research has potential to ‘change the world’

    U.S. Department of Energy Secretary Rick Perry toured the Princeton Plasma Physics Laboratory (PPPL) Thursday, Aug. 9, saying that national labs like PPPL have the potential to change the world through their scientific research. 

    “Fusion is incredibly important not just to this institution, not just to the Department of Energy, but to the world we live in,” Perry said during a meeting with PPPL staff. “If we are able to deliver fusion energy to the world, we can change the world forever.”

  • Data tools give microscopes unprecedented views of living and physical systems

    Techniques and tools for seeing fleeting arrangements of atoms during chemical reactions are advancing rapidly, allowing unprecedented insights into physical and living systems, according to experts in microscopy from around the world who gathered for a three-day conference at Princeton in July.

  • Princeton in space: Meet ISʘIS, heading to touch the sun

    Within the next month, NASA's Parker Solar Probe will lift off from Cape Canaveral, heading for a rendezvous with the sun. Onboard will be ISʘIS, an instrument suite led by Princeton’s David McComas to measure energetic particles from the sun’s corona and the solar wind.

  • A physics treasure hidden in a wallpaper pattern

    Thursday, Jul 19, 2018
    by Princeton University

    An international team of scientists has discovered a new, exotic form of insulating material with a metallic surface that could enable more efficient electronics or even quantum computing. The researchers developed a new method for analyzing existing chemical compounds that relies on the mathematical properties like symmetry that govern the repeating patterns seen in everyday wallpaper.
