An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, ...

New experiments using trapped one-dimensional gases -- atoms cooled to the coldest temperatures in the universe and confined so that they can only move in a line -- fit with the predictions of the ...

A breakthrough in theoretical physics is an important step towards predicting the behavior of the fundamental matter of which our world is built. It can be used to calculate systems of enormous ...
