WebCooling with Superfluid Helium Ph. Lebrun 1 and L. Tavian CERN, Geneva, Switzerland . Abstract . The technical properties of helium II ( superfluid helium) are presented in … WebWe have investigated the formation of helium droplets in two physical situations. In the first one, droplets are atomised from superfluid or normal liquid by a fast helium vapour flow. In the second, droplets of normal liquid are formed inside porous glasses during the process of helium condensation. The context, aims, and results of these experiments are reviewed, …

It is shown that at absolute zero a quantum liquid can possess the property of superfluidity (§ … WebHelium-3 (3 He) has superfluid phases closely related to topological insulators and topological superconductors.In geometrical confinement, 3 He is expected to support …
WebPart I of this article studied the specific heats of planar alternating layered Ising models with strips of strong coupling J1 sandwiched between strips of weak coupling J2, to illustrate qualitatively the effects of connectivity, proximity, and enhancement in analogy to those seen in extensive experiments on superfluid helium by Gasparini and coworkers. It was … WebBeschreibung. Das Phänomen der Suprafluidität wurde bislang nur bei den Helium-Isotopen 4 He und 3 He sowie in diversen Quantengasen wie 6 Li beobachtet. Sie gehen in den …
