Physicists have used a machine-learning method to identify surprising new twists on the non-reciprocal forces governing a many-body system. The work is one of the relatively few instances of using AI ...

At the Columbia Plasma Physics Lab, researchers are tackling one of the most pressing challenges in creating clean energy: making nuclear fusion a viable power source. Unlike nuclear fission—the type ...

Plasma is usually introduced as the stuff of stars and fusion reactors, a searing soup of charged particles that has little in common with the ice in a household freezer. Yet new experiments show that ...
