Crystals take a chill pill: A thermomechanical theory of low-temperature melting
Copper fields: Quantum criticality in high-temperature cuprate superconductors
Unexpected finding shows nanoparticles keep their internal crystal structure while flexing like droplets
A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal ...
Superabsorbing ring could make light work of snaps
A quantum effect in which excited atoms team up to emit an enhanced pulse of light can be turned on its head to create 'superabsorbing' systems to make the 'ultimate camera pixel'.
New study suggests more and longer atmospheric stagnation events due to global warming
Distant quakes trigger tremors at US waste-injection sites, says study
Large earthquakes from distant parts of the globe are setting off tremors around waste-fluid injection wells in the central United States, says a new study. Furthermore, such triggering of minor quakes by ...
New phenomenon could lead to novel types of lasers and sensors
There are several ways to "trap" a beam of light—usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method ...
Physics team entangles photons that never coexisted in time
16 atomic ions simulate a quantum antiferromagnet
(Phys.org) —Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter ...
How graphene and friends could harness the Sun's energy
(Phys.org) —Combining wonder material graphene with other stunning one-atom thick materials could create the next generation of solar cells and optoelectronic devices, scientists have revealed.
Movement of pyrrole molecules defy 'classical' physics
(Phys.org) —New research shows that movement of the ring-like molecule pyrrole over a metal surface runs counter to the centuries-old laws of 'classical' physics that govern our everyday world.
Propylene oxide: Light may recast copper as chemical industry 'holy grail'
Wouldn't it be convenient if you could reverse the rusting of your car by shining a bright light on it? It turns out that this concept works for undoing oxidation on copper nanoparticles, and it could lead to an environmentally ...
Physicists use metamaterials to observe giant photonic spin Hall effect
(Phys.org) —Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have once again demonstrated the incredible capabilities of metamaterials – artificial ...
