Optical billiards break new ground in quantum chaos

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 […]

Grand challenges for the US

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 […]

Getting all entangled up

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 […]
