• New theory clarifies why tunnel magnetoresistance oscillates with barrier thickness

  14 juillet
  Researchers have developed a new theory that explains why tunnel magnetoresistance (TMR)—used in magnetic memory and other technologies—oscillates with changes in the thickness of the insulating barrier within a magnetic tunnel junction (MTJ). This oscillation was clearly observed when NIMS (…)

• World's most precise clock achieves 19-decimal accuracy with aluminum ion technology

  14 juillet
  There's a new record holder for the most accurate clock in the world. Researchers at the National Institute of Standards and Technology (NIST) have improved their atomic clock based on a trapped aluminum ion. Part of the latest wave of optical atomic clocks, it can perform timekeeping with (…)

• Researchers demonstrate error-resistant quantum gates using exotic anyons for computation

  14 juillet
  The quantum computing revolution draws ever nearer, but the need for a computer that makes correctable errors continues to hold it back.

• Researchers make key advances in radiation detection

  14 juillet
  Researchers in the Oregon State University College of Engineering have developed new technology for uranium enrichment measurement and trace element detection, vital for nuclear nonproliferation and supporting the development and operation of next-generation nuclear reactors.

• Patterns of patterns : Exploring supermoiré engineering

  14 juillet
  A few years ago, physicists were surprised to learn that stacking and subtly twisting two atomically thin layers of an electronic material like graphene creates a pattern that changes the material's properties and can even turn it into a superconductor. This superimposed grid, like what (…)
