Copper fields: Quantum criticality in high-temperature cuprate superconductors
Crystals take a chill pill: A thermomechanical theory of low-temperature melting
Swimming upstream: Flux flow reverses for lattice bosons in a magnetic field
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 ...
Physics team entangles photons that never coexisted in time
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'.
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.
New study suggests more and longer atmospheric stagnation events due to global warming
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.
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 surprised by disappearing and reappearing superconductivity in iron selenium chalcogenides
(PhysOrg.com) -- Superconductivity is a rare physical state in which matter is able to conduct electricity -- maintain a flow of electrons -- without any resistance. This phenomenon can only be found in certain ...
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 ...
Physicists demonstrate quantum plasmons in atomic-scale nanoparticles
Addressing a half-century-old question, engineers at Stanford have conclusively determined how collective electron oscillations, called plasmons, behave in individual metal particles as small as just a few nanometers in diameter. ...
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 ...
