Study finds evidence of resonant Raman scattering from surface phonons of Cu(110)
Researchers at Johannes Kepler University in Linz have been investigating the physical properties of Cu(110), a surface attained when cutting a single copper crystal in a specific direction, for several years. Their most ...
Using machine learning to narrow down the possibilities for a better quantum tunneling interface
A pair of researchers at Fudan University in China has used machine learning to narrow the list of possible improved tunneling interface configurations for use in transistors. They have published their results in Physical ...
Scientists engineer quantum processor to emulate a small organic molecule
A team of quantum computer physicists at UNSW Sydney has engineered a quantum processor at the atomic scale to simulate the behavior of a small organic molecule, solving a challenge set some 60 years ago by theoretical physicist ...
