Density Functional Theory

Auteur
Aleksey E. Kuznetsov obtained his Ph.D. in Physical Chemistry at the Department of Chemistry and Biochemistry, Utah State University, USA in 2003, after three years of doctorate studies with a specialization in Computational/Theoretical Chemistry. He has been working in various subareas of this field of research since 2000. After several postdoctoral and visiting professor positions in Germany, the United States, and Brazil, Dr. Kuznetsov obtained a permanent faculty position at the Department of Chemistry, Universidad Técnica Federico Santa Maria, Santiago, Chile. He has been working there since 2019, focusing his research on the computational design of various complexes of porphyrins, including core-modified porphyrins, with nanoparticles, fullerenes, and graphenes, along with studies of transition metal complexes, organic compounds with pharmacological applications, and more.

Density Functional Theory: Fundamental Theory, Key Methods, and Applications provides a thorough and detailed explanation and overview of this important computational quantum mechanical modeling method and its applications. chapters are structured to be easier to understand and more accessible to the target audience. Split into three distinct sections, the book examines foundational knowledge surrounding DFT, covering key concepts such as the Thomas-Fermi model and Hohenberg-Kohn-Sham theory, looking at exchange-correlation functionals, the advantages and disadvantages of DFT compared to MO theory and other methods before exploring areas of future DFT development. The second section then examines practical methods and approaches for DFT, looking at the types of density functionals such as LSDA, GGA and meta-GGA functionals, hybrid functionals, DFTB methods, dispersion corrected functionals, Time-Dependent DFT and the Plane-wave approach. It also looks at relations between DFT and ab initio molecular dynamics and the QM/MM approach. The final section then focuses on applications and some useful case studies of use of DFT in different areas, whilst weighing up strengths and weaknesses in such applications.
