Unfrozen mystery: Water reveals a new secret

Using revolutionary new techniques, a team led by Carnegie's Malcolm Guthrie has made a striking discovery about how ice behaves under pressure, changing ideas that date back almost 50 years. Their findings could alter our ...

A quantum pump without a crank

Pumps, in a nutshell, are devices that use cyclic motion to attain the steady transport of some cargo. In a bicycle pump, the repeated up and down strokes of a piston create air flow. In a Archimedean screw pump, water is ...

Physicists investigate onset of effective mass

(Phys.org) —Although mass may seem to be a fairly straightforward concept, from a physics perspective it can be much more complex than weighing an object and reading off a number in grams. For instance, an object's mass ...

Researchers discover skyrmions can split like biological cells

Scientists at the U.S. Department of Energy's Ames Laboratory have discovered that skyrmions— a type of quasiparticle with properties that could lead to the next generation of data storage and transfer— reproduce by splitting ...

Friction almost vanishes in microscale graphite

(Phys.org) -- In the phenomenon of superlubricity, two solid surfaces can slide past each other with almost no friction. The effect occurs when the solid surfaces have crystalline structures and their lattices are rotated ...

Exerting better control over matter waves

(PhysOrg.com) -- “The concept of matter waves is at the heart of quantum mechanics,” Oliver Morsch tells PhysOrg.com. “At the beginning of the last century, scientists discovered that solid particles could exhibit properties ...

Scientists create atomic scale, 2-D electronic kagome lattice

Scientists from the University of Wollongong (UOW), working with colleagues at China's Beihang University, Nankai University, and Institute of Physics at Chinese Academy of Sciences, have successfully created an atomic scale, ...
