bubble when liquids are locally heated. We successfully observe that the heated atoms
scatter the neighboring nonheated atoms and make a bubble, and then the bubble is cooled
and compressed by the surrounding liquids. The bubble dynamics in this process agrees
with the results of the Rayleigh-Plesset equation which describes the dynamics of a bubble
in terms of macroscopic hydrodynamics. In this way, we clarify that the hydrodynamic …
