A simple spin system with self-interaction is proposed and studied where the interaction among spins is taken into account within a mean field model. The self-interaction, which turns out to be a… (More)

The dynamical behavior of a system consisting of a (heavy) piston and two rectangular boxes, each containing two hard disks and in contact with the piston, is studied based on a projection operator… (More)

We investigate some statistical mechanical properties of a system consisting of two hard spheres in a D-dimensional rectangular box (D=1, 2, ...). We give a theoretical method for computing a… (More)

In this paper we investigate some statistical mechanical properties of systems consisting of two hard disks in a circular cavity and two hard spheres in a cylindrical pore. Both systems conserve not… (More)

Magnesium alloys containing long-period-stacking ordered (LPSO) phases have attracted considerable attention because they have been reported to exhibit excellent mechanical properties, including high… (More)
