Critical behavior of the liquid gas transition of 4 He confined in a silica aerogel
Geoffroy Aubry, Fabien Bonnet, Mathieu Melich +3
We have studied 4 He confined in a 95% porosity silica aerogel in the vicinity of the bulk liquid gas critical point. Both thermodynamic measurements and light scattering experimen…
Condensation of helium in aerogels and athermal dynamics of the Random Field Ising Model
Geoffroy Aubry, Fabien Bonnet, Mathieu Melich +4
High resolution measurements reveal that condensation isotherms of He in a silica aerogel become discontinuous below a critical temperature. We show that this behaviour does no…
Suppression of Aggregation in Natural-Semiflexible/Flexible Polyanion Mixtures, and Direct Check of the OSF Model using SANS
Fabien Bonnet, Ralph Schweins, François Boué +1
Aggregation and other interactions are suppressed for a biological semiflexible polyelectrolyte, hyaluronan (HA), when it is embedded in a mixture with another negatively charged a…
Probing helium interfaces with light scattering : from fluid mechanics to statistical physics
Pierre-Etienne Wolf, Fabien Bonnet, Sylvain Perraud +3
We 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 f…
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…
