A model for exchange in liquid 3He

an appropriate model for exchange rate predictability in iran: comparing potential forecastability

nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...

’Fast Exchange’ model visualized with 3He confined in aerogel: a Fermi liquid in contact with a Ferromagnetic solid

Magnetic susceptibility of liquid 3He

He is a model of Fermi liquid, isotropic, its Fermi temperature is attainable and the interaction between atoms can be controlled by changing the pressure on the liquid. In this paper we present accurate cw-NMR measurements of the nuclear magnetic susceptibility of liquid He as a function of temperature and pressure. The emphasis has been placed in reliable thermometry, He pressure measurements...

Antiferromagnetic indirect exchange in 3He adsorbed layers

2014 We propose a new mechanism for indirect exchange in highly dense 3He adsorbed layers. This antiferromagnetic coupling arises from virtual exchange of particles between the solid layer and the liquid. It should predominate by more than one order of magnitude over the various ferromagnetic mechanisms proposed in the literature. It accounts for the sign and the order of magnitude of the Curie...

Liquid-gas phase transition in 3He

A mean field approach is used to investigate the liquid-gas phase transition in 3He. The method provides a reasonable prédiction for the vapour pressure in the whole région of températures. The prédictions for the critical point and the température dependence of the liquid and gas densities along the coexistence line are also discussed. J. Physique 48 (1987) 911-914 JUIN 1987, Classification Ph...
