Temperature of systems out of thermodynamic equilibrium
Jean-Luc Garden, Jacques Richard, Hervé Guillou
Two phenomenological approaches are currently used in the study of the vitreous state. One is based on the concept of fictive temperature introduced by Tool [Jour. Research Nat. Bu…
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…
Macroscopic non-equilibrium thermodynamics in dynamic calorimetry
Jean-Luc Garden
What is really measured in dynamic calorimetric experiments is still an open question. This paper is devoted to this question, which can be usefully envisaged by means of macroscop…
Non-equilibrium heat capacity of polytetrafluoroethylene at room temperature
Jean-Luc Garden, Jacques Richard, H. Guillou +1
Polytetrafluoroethylene can be considered as a model for calorimetric studies of complex systems with thermodynamics transitions at ambient temperature. This polymer exhibits two p…
Magnon condensation into Q-ball in 3He-B
Yu. M. Bunkov, G. E. Volovik
The theoretical prediction of Q-balls in relativistic quantum fields is realized here experimentally in superfluid 3He-B. The condensed-matter analogs of relativistic Q-balls are r…
Free Energy Formalism for Particle Adsorption
Pierre Gosselin, Herve Mohrbach
The equilibrium properties of particles adsorption is investigated theoretically. The model relies on a free energy formulation which allows to generalize the Maxwell-Boltzmann des…
