  • Quantum oscillations defy expectations in this exotic material
    Scientists have uncovered an unusual form of electron behavior in zirconium pentatelluride, a quantum material that can act as both an insulator and a conductor. Under temperatures near absolute zero and magnetic fields reaching 60 tesla, electrons produced quantum oscillations that continued even after conventional physics predicted they should disappear.
  • A new recipe unlocks “impossible” nanocrystals for LEDs, implants, and superconductors
    Scientists have cracked a long-standing chemistry problem, creating nanocrystals from tough metal nitrides that were previously extremely difficult to produce at this scale. The breakthrough could turn familiar materials used in LEDs, implants, and superconductors into building blocks for flexible electronics, printable devices, and other technologies.
  • Scientists turn one of the hardest plastics to recycle into high-performance engine lubricant
    Researchers have discovered a way to turn notoriously difficult-to-recycle PVC plastic into a key ingredient used in high-performance lubricants such as engine oil. The technique could give mountains of plastic waste a valuable second life while making lubricant production more sustainable.
  • Scientists catch a hidden electronic state forming in just 30 femtoseconds
    Scientists watched a light-triggered hidden state form inside a material in only 30 femtoseconds, revealing a step that had never been seen before. The material first entered a fleeting electronic state in which its bonds reorganized in a repeating pattern, followed by tiny atomic shifts. This ultrafast pathway could offer a new way to control […]
  • MIT physicists discover electrons rebuilding like ice inside a quantum material
    MIT physicists found that two electronic phases inside the same quantum material emerge through surprisingly different mechanisms—one smoothly and the other in expanding pockets resembling growing ice crystals. The discovery could help explain how exotic properties such as superconductivity and magnetism develop and coexist.
  • Tiny quantum engines reveal useful energy hiding in “waste heat”
    A tiny machine made from just an atom and particles of light may sound impossibly simple, but it raises a surprisingly difficult question: what counts as heat, and what energy can still do useful work? University of Basel researchers have developed a theoretical framework that brings quantum physics and thermodynamics into better agreement for these […]
