Charge flow in metals and mass flow in a neutral Fermi liquid show distinct profiles and are governed by different conservation properties. The connections between these two aspects of flow become apparent when we study the viscous flow of normal liquid 3He in the presence of aerogel. While the thermal flow is trivially affected, we predict that the resistance to mass flow shows a crossover fro...

We show that small amounts of 3He atoms, added to a 4He drop deposited on a flat cesium surface at zero temperature, populate bound states localized at the contact line. These edge states show up for drops large enough to develop well defined surface and bulk regions together with a contact line, and they are structurally different from the well-known Andreev states that appear at the free surf...

The ground-state properties of one-dimensional 3He are studied using quantum Monte Carlo methods. The equation of state is calculated in a wide range of physically relevant densities and is well interpolated by a power-series fit. The Luttinger liquid theory is found to describe the long-range properties of the correlation functions. The density dependence of the Luttinger parameter is explicit...

2014 In spin-polarized atomic hydrogen, the way to low T and high density is restricted by the Kapitza resistance. This is calculated, together with the corresponding characteristic time, for one channel : from H gas to liquid helium ripplons. J.

We study within the Faddeev framework the 3He( e, e′p)d as well as the 3He( e, e′p)pn and 3He( e, e′n)pp reactions in order to extract information on the proton and neutron polarization in polarized 3He. We achieve clear analytical insight for simplified dynamical assumptions and define conditions for experimental access to important 3He properties. In addition we point to the possibility of me...

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...

The 3He(3He, 2p)4He and 3H(3H, 2n)4He reactions are studied in a microscopic cluster model. We search for resonances in the 3He+3He and 4He+p+p channels using methods that treat the twoand three-body resonance asymptotics correctly. Our results show that the existence of a low-energy resonance or virtual state, which could influence the 7Be and 8B solar neutrino fluxes, is rather unlikely. Our ...

An experimental determination of the single-particle mean kinetic energies for 3He along the T = 2.00 K isotherm in the dense liquid and in the solid hcp and bcc phases is reported. Deep-inelastic neutron scattering measurements at exchanged wave vectors ranging from 90.0 to 140.0 A(-1) have been performed in order to evaluate, within the framework of the impulse approximation, the molar volume...
