Scientists at Warwick have shown that a material treated for 40 years as a uniform, textbook superconductor is in fact a patchwork of different crystal structures throughout its bulk, using an advanced 3D imaging technique to see deep inside the crystal for the first time.

A team of researchers led by the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) developed an approach that enabled them to directly observe how electrons interact with defects in advanced semiconductor devices in unprecedented detail. The team’s methodology included an innovative simulation tool that enabled accurate theoretical interpretations of its experimental observations. […]

Cornell physicists have discovered that minimizing disorder, not varying electron count, is the key factor for controlling superconductivity in the unique material iron selenide (FeSe), a new insight for understanding high-temperature superconductors.

Physicists at The City College of New York have demonstrated a new way to transfer microwave signals onto light using magnetic waves inside a layered semiconductor. The work establishes a materials platform for building interfaces that could one day link quantum computers through optical networks. The research, titled “Microwave-to-optical transduction using magnon–exciton coupling,” was led […]

A Stanford team has documented the first direct observation of quantum jumps of sound in a mechanical resonator, completing an arc of scientific exploration that started more than 100 years ago.

Quantum computers are no longer theoretical concepts. Today, they are being developed to tackle a range of complex problems, including exploring financial risk, modeling complex molecules and optimizing massive logistics networks. However, until now, there has been no way to benchmark the computational power of different systems on the same scale to see how they […]
