90-year-old ‘second sound’ quantum theory observed in superfluid helium Physicists at MIT have achieved a major feat, capturing a bizarre quantum effect called second sound in superfluid helium. This breakthrough, based on a theory proposed nearly a century ago, sheds light on the fundamental behavior of quantum materials and opens up new possibilities for future […]
In a first, Chinese scientists monitor heat flow at atomic level using electron beam
In a first, Chinese scientists monitor heat flow at atomic level using electron beam For years, scientists have known that phonons (vibrations of atoms) carry heat through solids. However, the ability to directly observe and manipulate these atomic-level processes has been a formidable challenge. Recently, a groundbreaking development in China has opened new doors in […]
