Recent advances in laser technology have enabled the exploration of previously inaccessible regimes where electrons interact with ultra-intense electromagnetic fields. These interactions drive ...

Physicists have taken a first step in understanding quantum emergence -- the transition from 'one-to-many' particles -- by studying not one, not many, but two isolated, interacting particles. The ...

Solving puzzles experimentally is enjoyable for many researchers. However, there are some puzzles that force even the best puzzlers to nominate modeling over experimental approaches to help decipher ...
