During chemical reactions, atoms in the reacting substances break their bonds and re-arrange, forming different chemical ...

New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws ...

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 ...

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 ...

Rotational dynamics explained through a 1935 physics textbook. Explore classic diagrams and timeless explanations that break down torque, angular motion, and rotational principles in a clear, ...

The 2023 Nobel Prize in Physics has been awarded to three researchers for their contributions to attosecond science. The prize honors Pierre Agostini of the Ohio State University, Ferenc Krausz of the ...

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 ...
