Theoretical condensed-matter physics

Our research interests lie in developing computational methods and programs for carrying out first-principles modeling/simulations of complex materials and phenomena. A pioneer in computational physics and computational materials science, his first-principles approaches (i.e., without adjustable parameters) based on the local density approximation, have provided a universal method for treating all materials. Applications of his FLAPW method are focused on the structural, electronic, magnetic, optical and mechanical properties of metals, semiconductors, insulators, large molecular clusters, complex bulk compounds and alloys, low-dimensional systems (surfaces, thin films and multilayers) and defects (impurities, vacancies, faults, grain boundaries and dislocations). Very recently he and his colleagues have parallelized the FLAPW code on the Cray T3E and the IBM SP4 computers and have demonstrated very good scaling with up to 512 processors. Freeman is the 13th most cited physicist in the ISI listing of over 512,000 physicists worldwide.
