Abstract

The behavior of quantum fluids (4He and H2) within nanopores is explored in various regimes, using several different methods. A focus is the evolution of each fluid's behavior as pore radius R is increased. Results are derived with the path integral Monte Carlo method for the finite temperature (T) behavior of quasi-one-dimensional (1D) liquid 4He and liquid H2, within pores of varying R. Results are also obtained, using a density functional method, for the T=0 behavior of 4He in pores of variable R.
