The effective mass of two--dimensional 3He
J. Boronat, J. Casulleras, V. Grau +2
We use structural information from diffusion Monte Carlo calculations for two--dimensional 3He to calculate the effective mass. Static effective interactions are constructed from t…

Layer- and bulk roton excitations of 4He in porous media
V. Apaja, E. Krotscheck
We examine the energetics of bulk and layer-roton excitations of 4He in various porous medial such as aerogel, Geltech, or Vycor, in order to find out what conclusions can be drawn…

Excitations in confined helium
V. Apaja, E. Krotscheck
We design models for helium in matrices like aerogel, Vycor or Geltech from a manifestly microscopic point of view. For that purpose, we calculate the dynamic structure function of…
