ABSTRACT
We present an overview of our work in developing hydrodynamic-
based methods for studying the structure and quantum dynamics of
rare-gas clusters. We use a hydrodynamical approach based on the
Bohm description of quantum mechanics (QM) to satisfy an orbital-
free density functional-like Euler-Lagrange equation for the ground
state of the system. In addition, we use an information theoretical
approach to obtain the optimal density function derived from a
series of statistical sample points in terms of density approximates.
These are then used to calculate an approximation to the quantum
force in the hydrodynamic description. We also show how this
approach can be extended to finite temperature and use this to
examine the thermodynamic properties of rare-gas clusters with up
to 100 atoms.
