Quantum effects lead to more powerful battery charging

(Phys.org)—Physicists have theoretically shown that, when multiple nanoscale batteries are coupled together, they can be charged faster than if each battery was charged individually. The improvement arises from collective ...

Natural systems show nonlocal correlations

Classical correlations are part of our everyday life. For instance, if one always puts on a pair of socks of the same color and shape, looking at the color or shape of one sock determines the color or shape of its pair. Even ...

From black holes to helium

A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space—is also true for cold helium atoms that can be studied in laboratories.

New technique for creation of entangled photon states

Members of the Faculty of Physics at the Lomonosov Moscow State University have elaborated a new technique for creating entangled photon states. They have described their research in an article published in the journal Physical ...

Looking for entangled atoms in a Bose-Einstein condensate

Using a Bose-Einstein condensate composed of millions of sodium atoms, researchers at the Georgia Institute of Technology have observed a sharp magnetically-induced quantum phase transition where they expect to find entangled ...

Black holes on an electronic chip

A team of theoretical physicists has proposed a way to simulate black holes on an electronic chip. Additionally, the technology used to create these lab-made black holes may be useful for quantum technologies. The researchers ...
