• The first experimental observation of Dirac exceptional points

  27 avril
  Exceptional points (EPs) are unique types of energy-level degeneracies that occur in non-Hermitian systems. Since their existence was first proposed more than a century ago, physicists have only been able to experimentally observe two types of EPs, both of which were found to give rise to exotic (…)

• Ultrafast optical technique reveals how electrical double layers form in liquids

  25 avril
  Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions from the liquid. This creates two distinct charged regions: the surface itself and a counter-charged region in the liquid: the so-called electrical double layer. While (…)

• Magnetic confinement advance promises 100 times more fusion power at half the cost

  25 avril
  A team of fusion researchers at TAE Technologies, Inc., in the U.S., working with colleagues from the University of California, has developed a new type of fusion technology that the company claims produces 100 times the power of other designs while costing just half as much to run. Their study (…)

• Observatory develops high-efficiency muon detection system with novel plastic scintillator design

  25 avril
  Researchers from Sun Yat-sen University (SYSU) and the Institute of High Energy Physics (IHEP) have developed a novel top veto tracker system for the Taishan Antineutrino Observatory (TAO) experiment.

• Hey, what are these curved green flashes above my polymer semiconductor ?

  25 avril
  In every scientific discovery in the movies, a scientist observes something unexpected, scratches the side of his or her forehead and says "hmmmmm." In just such a moment in real life, scientists from Canada observed unexpected flashes of curved green light from a red light-emitting (…)
