Rotons, Superfluidity, and Helium Crystals
Fritz London understood that quantum mechanics could show up at the macroscopic level, and, in 1938, he proposed that superfluidity was a consequence of Bose-Einstein condensation. However, Lev Landau...

Thispaper provides a brief history of the evolution of theBerkeley experiments on macroscopic quantum effects in superfluid helium. Thenarrative follows the evolution of the experiments proceeding from thedetection of single vortex lines to vortex photography to quantizedcirculation in ³He to Josephson effects and superfluid gyroscopes inboth ⁴He and ³He. ©2006 American Institute of Physics
