Περίληψη:
We present a framework for studying vortex lattice patterns and their
structural transitions, using the Parrinello-Rahman (PR) method for
molecular-dynamics (MD) simulations. Assuming an interaction between
vortices derived from a Ginzburg-Landau field-theoretic context, we
extract the ground-state of a “vortex gas” using the PR-MD technique
and find it to be a triangular pattern. Other patterns are also obtained
for special initial conditions. Generalizations of the technique, such
as the inclusion of external potentials or excitation of quadrupolar
modes, are also commented upon. (c) 2005 Elsevier B.V. All rights
