A quantum degeneracy named after a Chinese yo-yo boosts the magnetization lifetime of a short chain of magnetic iron atoms by a factor of 1000.
Theorists have developed a model to explain how a protein structure keeps its position while being buffeted by currents.
Overlapping two 3D lattices with a relative twist opens the door to synthesizing crystals with diverse symmetries that showcase nontrivial band structures and novel properties.
When two identical periodic lattices overlap in space, with one twisted at an angle relative to the other, they form moiré lattices. The best-known examples are formed from stacked and rotated 2D sheets. These structures can possess fascinating properties not seen in their component layers. Twisted bilayer graphene, for example, can exhibit superconductor and Mott insulator behavior [1, 2]. Ce Wang of Tongji University in China and his colleagues now propose how to construct a 3D moiré lattice using two cubic optical lattices hosting ultracold atoms [3]. The researchers mathematically describe how two simple periodic structures, twisted relative to each other, can lead to 3D optical moiré patterns (Fig. 1). The result is a crystal-like structure with emergent properties that differ from those of the underlying simple lattices.
Far beneath the lush landscape of southern China, a sprawling subterranean laboratory aims to be the world’s first to crack a deep scientific enigma.
Inaction on the water crisis could put more than half of the world’s food production at risk by 2050, experts warned in a major report published Thursday.
Hundreds of papers have been written about the first known brown dwarf, Gliese 229B, since its discovery by Caltech researchers at the Institute’s Palomar Observatory in 1995. But a pressing mystery has persisted about this orb: It is too dim for its mass.
Sirish Subash is named “America’s Top Young Scientist” for his device PestiSCAND that can help detect harmful pesticide residue.
If it were up to Larry Ellison, the exorbitantly rich cofounder of software outfit Oracle, all of us will soon be smiling for the camera — constantly. Not for a cheery photograph, but to appease our super-invasive, if not totally omnipresent, algorithmic overseers.
As Business Insider reports, the tech centibillionaire glibly predicts that the wonders of AI will bring about a new paradigm of supercharged surveillance, guaranteeing that the proles — excuse us, “citizens” — all behave and stay in line.
“We’re going to have supervision,” Ellison said this week at an Oracle financial analysts meeting, per BI. “Every police officer is going to be supervised at all times, and if there’s a problem, AI will report that problem and report it to the appropriate person.”
