90-year-old ‘second sound’ quantum theory observed in superfluid helium
SMRTR summary
MIT physicists have directly observed "second sound," a quantum phenomenon where heat moves in waves rather than spreading gradually. Using lithium-6 atoms and radio waves, they filmed this effect in superfluid helium, providing visual evidence of a concept predicted in 1938. This breakthrough could advance astrophysics and superconductivity research, potentially improving our understanding of neutron stars and aiding the development of high-temperature superconductors for various applications.
