Testing quantum field theory in a quantum simulator

Quantum field theories are often hard to verify in experiments. Now, there is a new way of putting them to the test. Scientists have created a quantum system consisting of thousands of ultra cold atoms. By keeping them in ...

Mapping the edge of reality

Australian and German researchers have collaborated to develop a genetic algorithm to confirm the rejection of classical notions of causality.

Bell correlations measured in half a million atoms

(Phys.org)—Physicists have demonstrated Bell correlations in the largest physical system to date—an ensemble of half a million atoms at an ultracold temperature of 25 µK. The presence of Bell correlations indicates that ...

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 ...

Eavesdropping on the particular chatter on the sub-atomic world

Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear scientists are developing ...

Fragment tracking—insights into what happens in explosions

A bang and a swirl of dust from detonating 9 pounds of plastic explosive in the desert signaled the beginning of tests that—thanks to advances in high-speed cameras, imaging techniques and computer modeling—will help ...
