Modern Methods and Algorithms of Quantum Chemistry
This
book covers the following topics: Density functional theory, Ab initio molecular
dynamics, Post-Hartree-Fock methods, Molecular properties, Heavy-element
chemistry, Linear scaling approaches, Semiempirical and hybrid methods, Parallel
programming models and tools, Numerical techniques and automatic
differentiation, Industrial applications.
This note
presents advanced methods in quantum chemistry. Large systems are of particular
interest and serve to focus on Hartree-Fock theory and Density Functional Theory
with a notable selection of practical techniques for integral evaluation and
matrix construction. The Coulomb and exchange matrices are constructed, density
matrices purify, and large data sets necessary for quantum chemistry
calculations are stored and manipulated. The book gives insight into the
problems of large quantum chemistry calculations and presents the computational
techniques developed to overcome these problems, making it a most valuable aid
to researchers concerned with large molecular systems or with computational
chemistry.
This introductory note
provides a sound basis in quantum chemical theory. It is structured by a brief
overview of basic concepts, followed by close scrutiny of the GAMESS
computational chemistry package and its applications. The note provides a
starting point for the theory behind calculations performed in quantum chemical
chemistry; it can be suitable for those new to computational chemistry or for
students looking to get a foot in the door as regards practical tools for
molecular simulation.
