R. Stephen Berry [1] became 70 years old on April 9, 2001.[...]

A James Franck Distinguished Service Professor of Chemistry at the University of Chicago, R. Stephen Berry has worked on a variety of subjects ranging from strictly scientific matters to the analysis of energy use and resource policy.[...]

We present the real-space block renormalization group equations for fermion systems described by a Hubbard Hamiltonian on a triangular lattice with hexagonal blocks. The conditions that keep the equations from proliferation of the couplings are deriv...

We compare two recently proposed methods for the characterization of phase transitions in small systems. The usefulness of these techniques is evaluated for the case of structural transition in alanine-based peptides.

We apply a recently introduced method for global optimization to determine the ground state energy and configuration for model metallic clusters. The global minimum for a given N–atom cluster is found by following the damped dynamics of the N particl...

We investigate a theoretical model of molecular metalwire constructed from linear polynuclear metal complexes. In particular we study the linear Crn metal complex and Cr molecular metalwire. The electron density distributions of the model nanowire an...
