Research reveals new state of matter: a Cooper pair metal

The idea that boson-like Cooper pairs are responsible for this metallic state is something of a surprise, the researchers say, because there are elements of quantum theory that suggest this shouldn’t be possible. NOVEMBER 15, 2019 by Kevin Stacey, Brown University For years, physicists have assumed that Cooper pairs, the electron duos that enable superconductors to […]

Unique properties of quantum material explained for first time

This new understanding of the topological material will make it easier for engineers to use it in new applications. OCTOBER 23, 2019 by Steve Tally, Purdue University The characteristics of a new, iron-containing type of material that is thought to have future applications in nanotechnology and spintronics have been determined at Purdue University. The native material, […]

Surfing on waves in a one-dimensional quantum liquid

OCTOBER 18, 2019 by University of Luxembourg Physicists from the University of Luxembourg, together with international collaborators, have recently published an article in the internationally renowned journal Physical Review Letters. In this article, they demonstrate how quantum-mechanical interference effects could allow experimenters to better study the properties of particles trapped in quantum liquids via resonances in the […]

Scientists observe a single quantum vibration under ordinary conditions

Studying a common material at room temperature, researchers bring quantum behavior “closer to our daily life.” Jennifer Chu | MIT News OfficeOctober 6, 2019 When a guitar string is plucked, it vibrates as any vibrating object would, rising and falling like a wave, as the laws of classical physics predict. But under the laws of […]
