  • New laser technique images quantum world in a trillionth of a second December 10, 2019
    For the first time, researchers have been able to record, frame-by-frame, how an electron interacts with certain atomic vibrations in a solid. The technique captures a process that commonly causes electrical resistance in materials while, in others, can cause the exact opposite—the absence of resistance, or superconductivity.
  • Physicists image electrons flowing like water for the first time December 10, 2019
    Physicists at the Weizmann Institute of Science in Israel have imaged electrons flowing viscously through a nanodevice, just like water flowing through a pipe. Long predicted but only now visualized for the first time, this curious new behavior for electrons has important implications for future electronic devices.
  • The X17 factor: A particle new to physics might solve the dark matter mystery December 10, 2019
    A team of scientists in Hungary recently published a paper that hints at the existence of a previously unknown subatomic particle. The team first reported finding traces of the particle in 2016, and they now report more traces in a different experiment.
  • New understanding of charge transport reveals an exotic quantum mechanical regime December 10, 2019
    In work that may have broad implications for the development of new materials for electronics, Caltech scientists for the first time have developed a way to predict how electrons interacting strongly with atomic motions will flow through a complex material. To do so, they relied only on principles from quantum mechanics and developed an accurate […]
  • Ultrafast stimulated emission microscopy of single nanocrystals December 9, 2019
    The ability to investigate the dynamics of single particle at the nano-scale and femtosecond level remained an unfathomed dream for years. It was not until the dawn of the 21st century that nanotechnology and femtoscience gradually merged together and the first ultrafast microscopy of individual quantum dots (QDs) and molecules was accomplished. Ultrafast microscopy studies […]
  • Liquid flow is influenced by a quantum effect in water December 9, 2019
    Researchers at EPFL have discovered that the viscosity of solutions of electrically charged polymers dissolved in water is influenced by a quantum effect. This tiny quantum effect influences the way water molecules interact with one another. Yet, it can lead to drastic changes in large-scale observations. This effect could change the way scientists understand the […]
  • Spin on perovskite research advances potential for quantum computing December 9, 2019
    The next generation of information technology could take advantage of spintronics—electronics that use the minuscule magnetic fields emanating from spinning electrons as well as the electric charges of the electrons themselves—for faster, smaller electronic devices that use less energy.
  • In surprise breakthrough, scientists create quantum states in everyday electronics December 9, 2019
    After decades of miniaturization, the electronic components we've relied on for computers and modern technologies are now starting to reach fundamental limits. Faced with this challenge, engineers and scientists around the world are turning toward a radically new paradigm: quantum information technologies.
  • Gamma-ray laser moves a step closer to reality December 6, 2019
    A physicist at the University of California, Riverside, has performed calculations showing hollow spherical bubbles filled with a gas of positronium atoms are stable in liquid helium.
  • A platform for stable quantum computing, a playground for exotic physics December 5, 2019
    Move over Godzilla vs. King Kong—this is the crossover event you've been waiting for. Well, at least if you're a condensed matter physicist. Harvard University researchers have demonstrated the first material that can have both strongly correlated electron interactions and topological properties. Not entirely sure what that means? Don't worry, we'll walk you through it. […]
