Single Particle and Fermi Liquid Properties of He-3/--He-4 Mixtures: A Microscopic Analysis
E. Krotscheck, J. Paaso, M. Saarela +2
We calculate microscopically the properties of the dilute He-3 component in a He-3/--He-4 mixture. These depend on both, the dominant interaction between the impurity atom and the…
Quantum sticking, scattering and transmission of 4He atoms from superfluid 4He surfaces
C. E. Campbell, E. Krotscheck, M. Saarela
We develop a microscopic theory of the scattering, transmission, and sticking of 4He atoms impinging on a superfluid 4He slab at near normal incidence, and inelastic neutron scatte…
Concentration Dependence of the Effective Mass of He-3 Atoms in He-3/He-4 Mixtures
E. Krotscheck, M. Saarela, K. Schoerkhuber +1
Recent measurements by Yorozu et al. (S. Yorozu, H. Fukuyama, and H. Ishimoto, Phys. Rev. B 48, 9660 (1993)) as well as by Simons and Mueller (R. Simons and R. M. Mueller, Czhechos…
Phase diagram of the 2D He in the density-temperature plane
F. V. Kusmartsev, M. Saarela
Thin He films adsorbed to weakly attractive substrates form nearly 2D layers. We describe the vortices in 2D superfluid He like quasiparticles. With the aid of a variationa…
