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 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 ...

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

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 ...

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 ...

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, ...

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 ...
