A Model for the Lambda Transition of Helium 4
T. Fliessbach
Guided by the analogy to the Bose-Einstein condensation of the ideal Bose gas (IBG) we propose a new model for the lambda transition of liquid helium. Deviating from the IBG our mo…

Effective Ginzburg-Landau model for superfluid 4 He
T. Fliessbach
We propose an effective Ginzburg-Landau energy functional for superfluid helium that is motivated by the ideal Bose gas model. The parameters of this phenomenological model are adj…
