A team of physicists has made a significant breakthrough in understanding the temperature of the second sound, a phenomenon in which heat is conducted without the transfer of matter. The researchers used a microscale thermometer to measure the temperature of second sound in solid materials at cryogenic temperatures. This measurement was possible due to a technique developed by the team that allowed them to fill a gap in the study of this phenomenon that had been present since its discovery in the 1930s.

The study of second sound has been limited by the lack of a direct method to measure its temperature, and this new technique provides a step forward in understanding heat conduction and the fundamental laws of thermodynamics. The researchers hope that their work will lead to further insight into the behavior of second sound and its potential applications in fields such as electronics and materials science. By understanding the temperature of second sound, scientists can work to exploit its properties for practical applications at the nanoscale level.

This research opens up new possibilities for studying and manipulating heat conduction at an atomic level. The findings have profound implications for our understanding of thermodynamics and could lead to advances in technology and materials science. As we continue to explore this fascinating area of physics, we can expect even more groundbreaking discoveries that will change our world for years to come.
