Unbalanced superfluid could be akin to exotic matter found in quark star
This is a 3-dimensional projection of an image of a phase separated atomic cloud. The tall central (semi-transparent) region consists of paired fermionic 6 Li atoms, and is believed to be a superfluid. The shorter (opaque) peaks on either side, as well as the faint ring around the bottom, are unpaired atoms which have been expelled from the paired central region. The light in the background is a representation of the probe laser beam used to image this cloud.
In the bizarre and rule-bound world of quantum physics, every tiny spec of matter has something called "spin" - an intrinsic trait like eye color - that cannot be changed and which dictates, very specifically, what other bits of matter the spec can share quantum space with. When fermions, the most antisocial type of quantum particle, do get together, they pair up in a wondrous dance that enables such things as superconductivity.
For the first time, researchers at Rice University have succeeded in creating and observing an elusive and long-sought quantum state - a superfluid of fermions with mismatched numbers of dance partners. Despite more than 40 years of theoretical musings about what would occur in such a case, the result - a cluster of matched pairs surrounded by a cloud of would-be dance partners - was largely unexpected.

NASA keeps watch over space explosions

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
