• Physicists take Hall effect in a new direction

  31 août
  Carnegie Mellon University scientists have uncovered a new phenomenon that challenges a longstanding assumption about how electronic materials respond to magnetic fields. The discovery broadens the fundamental understanding of the Hall effect, a principle widely used to measure the magnetic and (…)

• Physicists finally put Feynman's path integral to the test

  31 août
  For nearly 80 years, physicists have relied on a thought experiment created by Richard Feynman to predict how quantum particles behave. For the first time, researchers in China have tested this trick directly in the lab.

• Hollow-core fiber platform could help different quantum technologies connect

  30 août
  Quantum technologies promise secure communication networks, powerful forms of computing and new sensing tools. One of the major challenges, however, is that different quantum systems often operate at different wavelengths of light. Quantum memories, trapped ions and other quantum devices may (…)

• How plastic welds retain a molecular 'memory' of their former surfaces to strengthen pipe joints

  29 août
  Welding plastic is a critically important part of everyday engineering—especially for preventing leaks in underground water and gas pipes. For decades, engineers have understood that a properly welded joint in polyethylene pipe can be just as strong as the pipe itself, if not stronger. However, (…)

• Diamond clock combines two signals to cut temperature-driven drift

  28 août
  Despite all the advertisements for engagement rings and necklace gifts, natural diamonds are imperfect. Their carbon atoms are arranged in a cubic lattice, but they nonetheless contain several types of crystallographic defects due to impurities that occasionally replace a carbon atom. The most (…)
