Evidence for a disorder driven phase transition in the condensation of 4He in aerogels
Fabien Bonnet, Thierry Lambert, Benjamin Cross +4
We report on thermodynamic and optical measurements of the condensation process of He in three silica aerogels of different microstructures. For the two base-catalysed aerogels…

Coherent quasiparticle transport in grain boundary junctions employing high-Tc superconductors
F. Tafuri, A. Tagliacozzo, D. Born +8
Magneto-fluctuations of the normal resistance RN have been reproducibly observed in YBa2Cu3O7-d biepitaxial grain boundary junctions at low temperatures. We attribute them to mesos…

Two dimensional curved disks on a sphere: the evolution of kinetic energy
J. R. Darias, N. Olivi-Tran
We put disks on a sphere between two parallels of this sphere. The disks have the curvature of the sphere and interact via a simplified Hertz law. We analyze the behavior of the to…
