NASA’s James Webb Space Telescope will see the first galaxies to form after the big bang, but to do that its instruments first need to get cold – really cold. On April 7, Webb’s Mid-Infrared Instrument (MIRI) – a joint development by NASA and ESA (European Space Agency) – reached its...

Producing entangled photons whose properties are interdependent is key to several quantum communication technologies. Most techniques for generating these photons make them exclusively in pairs, and those that can produce more than two photons are difficult to implement. But researchers have now made a chip-sized device that can generate bunches...

TEAM-UP Together, a new initiative by the American Institute of Physics (AIP) and key physics and astronomy societies, boldly takes the first steps toward achieving a goal of doubling the number of African Americans graduating from college with undergraduate degrees in physics and astronomy by 2030. The AIP Foundation has...

The discovery of superconductivity in two ever-so-slightly twisted layers of graphene made waves a few years ago in the quantum materials community. With just two atom-thin sheets of carbon, researchers had discovered a simple device to study the resistance-free flow of electricity, among other phenomena related to the movement of...

In an article recently published in the Journal of Applied Physics, researchers investigated the influence of strain and pressure on the superconductivity and electron-phonon coupling in magnesium diboride (MgB2). They also discussed the corresponding theoretical approaches and the future of nanostructure design. Background The discovery of MgB2 as a high-temperature superconductor with a...

A POSTECH research team led by Professors Gil-Ho Lee and Gil Young Cho (Department of Physics) has developed a platform that can control the properties of solid materials with light and measure them. Recognized for developing a platform to control and measure the properties of materials in various ways with light,...
