抄録

The superfluid transition temperature Tc is calculated for the 4He system in a model substrate of zeolite by the quantum lattice gas model. The reduction of Tc due to the geometry of the substrate is calculated by the quantum renormalization method. The result shows that Tc is proportional to 1⁄\sqrtL (L: the pore length), in contrast with the classical result that Tc∝1⁄L, and the superfluidity is expected to be observed experimentally unless the pore of zeolite is too long.
