Superfluid liquid hydrogen?
Recent work by Peter Toennies’ group in Göttingen has revealed convincing evidence for superfluidity in liquid hydrogen – thus adding a third liquid to the two, liquid He and liquid He, in which superfluididy is already known. Superfluids are numbered among the most peculiar and counter-intuitive of all materials. They have no viscosity at all. Thus, an object travelling in a pure superfluid mo...
متن کاملReheating after Supercooling in the Chiral Phase Transition
We study the conversion of the latent heat of a supercooled quark-gluon plasma into excitations of the pion field. Supercooling is predicted to occur in the late stages of the evolution of a quark-gluon plasma produced in energetic heavy-ion collisions, if the QCD phase transition is of first order. The supercooled, chirally symmetric state, which contains potential energy associated with an en...
متن کاملSuperfluid transition in superfluid 3He in radially compressed aerogel
The Spin Supercurrent and Bose-Einstein condensation of magnons similar to an atomic BEC was observed in 1984 in superfluid He-B. Recently we discovered 2 new types of BEC in superfluid He in deformed aerogel. The orbital part of the wave function orients along the deformation and changes the magnon-magnon interaction. In some cases it forms a magnon trap. We can do it for He-A by uniaxially co...
متن کاملA phase transition model for the helium supercooling
We build a predictive theory for the evolution of mixture of helium and supercooled helium at low temperature. The absolute temperature θ and the volume fraction β of helium, which is dominant at temperature larger than the phase change temperature, are the state quantities. The predictive theory accounts for local interactions at the microscopic level, involving the gradient of β. The nonlinea...
متن کاملCritical Flow of Superfluid Helium-4 through a Submicron Aperture: Width of the Critical Transition
1. EXPERIMENT We-have observed that the critical velocity of the _ flow of superfluid 4He through a submicron aperture exhibits fluctuations which increase with temperature. We have analyzed these fluctuations in order to gain information about the velocity dependence of the probability of occurrence of dissipative phase-slip events. These measurements were made with the same apparatus and duri...
