STABILITY OF THE HARD-SPHERE ICOSAHEDRAL QUASILATTICE

摘要

The stability of the hard-sphere icosahedral quasilattice is analyzed using the differential formulation of the generalized effective liquid approximation. We find that the icosahedral quasilattice is metastable with respect to the hard-sphere crystal structures. Our results agree with recent findings by McCarley and Ashcroft [Phys.Rev. B 49, 15 600 (1994)] carried out using the modified weighted density approximation. [References: 12]
