The superfluidity mechanism of He II
J. X. Zheng-Johansson, B. Johansson, P-I. Johansson
Based on a first principles treatment of the excitation states we show that superfluidity of superfluid He (He II) results from a reduction in the number of phonon wavevector $…

The Theory of Superfluidity of Helium
J. X. Zheng-Johansson
I present here a microscopic theory for the superfluidity of He (He II) derived from experiments, and answer its essential questions. With a "momenton" model, the superfluid is…
