Attosecond physics has emerged as a transformative approach to probing the ultrafast dynamics of electrons within atoms, molecules and solids. By utilising light pulses that last on the order of 10⁻¹⁸ ...

Quantum many-body physics explores emergent properties of many interacting quantum particles, which often have no counterpart in classical systems. Of particular interest is the study of ...

New experiments with ultra-cold atomic gases uncover universal physics in the dynamics of quantum systems. Penn State graduate student Yuan Le, the first author of the paper describing the experiments ...

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 ...
