Abstract
Mechanical simulations of a two-dimensional system of cyclic tetramers, studied in square () and hexagonal () boxes, demonstrate the existence of crystalline ; different structures are observed), rotator (), and fluid () phases ( is the area of the box with close-packed structure). Observed phase coexistences suggest first-order transitions.
