Ringing protons give insight into early universe

In the middle of the last century, physicists found that protons can resonate, much like a ringing bell. Advances over the last three decades have led to 3D pictures of the proton and significant insight into its structure ...

Dynamics of molecular rotors in bulk superfluid helium

Molecules immersed in liquid helium can probe superfluidity since their electronic, vibrational and rotational dynamics can provide valuable cues about the superfluid at the nanoscale. In a new report in Science Advances, ...
