A wire made from a perfect crystal can transmit electricity with no resistance
A delicate layer of gas can deflect an electron beam that is strong enough to pierce steel
But if the shape of the billiard table is changed from a rectangle to the shape of an athletic stadium, the system becomes chaotic and turns into a pool player’s nightmare. While chaotic billiards should be avoided in the pool hall, physicists and mathematicians welcome them as model systems for understanding the consequences of chaos […]
Along the way six “area volumes” have been published on the major subfields of physics – atomic, molecular and optical physics; plasma science; elementary particle physics; nuclear physics; condensed-matter and materials physics; and gravitational physics – along with four shorter volumes. These reports all make recommendations that are relevant to these specific areas. In the […]

In the last decade, however, a more constructive aspect of entanglement has emerged, and it is now seen as a valuable resource that could provide significant improvements in our powers of communication and computing. Now Paul Kwiat and Salvado Barraza-Lopez of the Los Alamos National Laboratory, and André Stefanov and Nicolas Gisin of the University […]

Techniques used to study soft condensed matter can be applied to living systems, but there are differences in the approaches of physicists and biologists, say Wilson Poon, Tom McLeish and Athene Donald
