Paper-thin optical lenses simple enough to mass produce like microchips could enable a new generation of compact optical devices. A team with researchers at the University of Tokyo and JSR Corp. fabricated and tested flat lenses called Fresnel zone plates (FZPs), but did so for the first time using only common semiconductor manufacturing equipment, the […]

Physicists have spent more than a century measuring and making sense of the strange ways that photons, electrons, and other subatomic particles interact at extremely small scales. Engineers have spent decades figuring out how to take advantage of these phenomena to create new technologies.

Diamond, often celebrated for its unmatched hardness and transparency, has emerged as an exceptional material for high-power electronics and next-generation quantum optics. Diamond can be engineered to be as electrically conductive as a metal, by introducing impurities such as the element boron.

MIT physicists have created a new ultrathin, two-dimensional material with unusual magnetic properties that initially surprised them before they went on to solve the complicated puzzle behind those properties’ emergence. As a result, the work introduces a new platform for studying how materials behave at the most fundamental level, the world of quantum physics.

Since the invention of the laser in 1960, nonlinear optics has aimed to broaden light’s spectral range and create new frequency components. Among the various techniques, supercontinuum (SC) generation stands out for its ability to produce light across a wide portion of the visible and infrared spectrum.

A team of physicists led by The City College of New York’s Lia Krusin-Elbaum has developed a novel technique that uses hydrogen cations (H+) to manipulate relativistic electronic bandstructures in a magnetic Weyl semimetal—a topological material where electrons mimic massless particles called Weyl fermions. These particles are distinguished by their chirality or “handedness” linked to […]

Alexander Hartmann, a physicist at the University of Oldenburg, in Germany, has introduced a new model to explain a common word puzzle phenomenon. In his paper published in the journal Physical Review E, he suggests that instances where a puzzle solver experiences a sudden insight that allows them to begin finding solutions that seemed hidden […]
