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, ...
Osaka Metropolitan University scientists investigated numerically the interaction between a quantized vortex and a normal fluid. Based on the experimental results, researchers decided the most consistent of several theoretical ...
