The Connection Between Collective Diffusion in Classic Liquids and the Superfluidity Phenomenon in Quantum Liquids

Authors: Alekseenko Victor Victorovich

This study suggests the mechanism for atomic motion in quantum liquids at low temperatures where the lifetime of the states that are responsible for atomic motion becomes macroscopically long. This mechanism is an analog to the motion of crowdions in the one-dimensional Frenkel-Kontorova model. Soliton-like atomic motion along linear directions, and the circular motions provide a means of explaining many macroscopic phenomena occurring at the transition of 4He to a superfluid state, such as the behavior of rotating superfluid helium and the flow potentiality of the superfluid phase. The thermodynamics of rotating 4He is considered under the assumption that Bose-Einstein condensate is not the ground state of Bose-Einstein liquid. An experiment is suggested in order to validate our approach.
