• Magnetic frustration in atacamite triggers dramatic cooling when exposed to strong fields

  27 juin
  Natural crystals fascinate with their vibrant colors, their nearly flawless appearance and their manifold symmetrical forms. But researchers are interested in them for quite different reasons: Among the countless minerals already known, they always discover some materials with unusual magnetic (…)

• Wafer lens changes X-ray beam size by more than 3,400 times

  27 juin
  Using only a single-crystal piezoelectric thin wafer of lithium niobate (LN) instead of the usual two-part structure, a group from Nagoya University in Japan has created a deformable mirror that changes X-ray beam size by more than 3,400 times. This improved tuning range enhances both imaging (…)

• Researchers demonstrate giant photonic isolation and gyration

  Researchers from the Illinois Grainger College of Engineering are the first to demonstrate a simple and tunable method for realizing asymmetric couplings in integrated photonics. Their findings, published in Physical Review Letters and selected as an Editor's Pick, provide insight into (…)

• Twisted trilayer graphene shows high kinetic inductance and quantum coherence

  Superconductivity is an advantageous physical phenomenon observed in some materials, which entails an electrical resistance of zero below specific critical temperatures. This phenomenon is known to arise following the formation of so-called Cooper pairs (i.e., pairs of electrons).

• Charge-spin coupling in room-temperature 2D ferromagnetic material

  26 juin
  What if electricity and magnetism, usually considered as separate or even competing forces in materials, could actually work together in harmony?
