Fermi liquid theory of Fermi-Bose mixtures
E. V. Thuneberg, T. H. Virtanen
We write down the basic equations of Fermi-liquid theory for mixtures of fermions and bosons, an example being 3He-4He mixtures at low temperatures. Basically the theory is identic…

Pendulum in Fermi liquid
Timo H. Virtanen, Erkki Thuneberg
The Fermi liquid theory formulated by Landau is a basic paradigm of the behavior of an interacting many-body system. We present a new application of this theory to calculate "Landa…

Structure of metastable 2D liquid helium
V. Apaja, M. Saarela
We present diffusion Monte Carlo (DMC) results on a new metastable, superfluid phase above the crystal ground state in two-dimensional 4He at densities > 0.065 1/A^2. The state is…
