Feynman liquid helium

WebIn this momentous paper Feynman set out a quantum mechanical explanation of the superfluidity of liquid helium at temperatures below the ‘lambda-point’ of 2.18K. Whilst the phenomenon had been observed and theorized upon since 1938, its account lacked an atomistic foundation. WebRichard Phillips Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as work in particle physics (he proposed the parton model). For his contributions to the development of quantum ...
