RT Journal Article T1 Two-dimensional H2 clusters : a path-integral Monte Carlo study A1 Gordillo, M.C. A1 Ceperley, D. M. K1 Clusters K1 Monte Carlo simulations AB We performed path-integral Monte Carlo simulations of two-dimensional H2 clusters of different sizes. The smaller of these clusters are superfluid at low temperatures. On increasing the size we observe the formation of a solidlike inner core and a liquidlike outer shell.
