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 ...

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 ...

BUFFALO, N.Y. — Imagine zooming into matter at the quantum scale, where tiny particles can interact in more than a trillion configurations at once. If that sounds complicated, it is: Physicists often ...
