Density Functional Theory with Python: Principles, Implementation, and Applications in Chemistry - Tapa blanda

Sinopsis

Reactive Publishing

Density Functional Theory with Python bridges the gap between quantum mechanical theory and practical computational chemistry. Written for researchers, graduate students, and chemical physicists, this volume provides a rigorous mathematical framework alongside functional numerical implementations.

Beginning with the foundational Hohenberg-Kohn theorems and the Kohn-Sham self-consistent field equations, the text systematically translates formal derivations into transparent, reproducible Python workflows. Rather than treating computational chemistry packages as black boxes, the architecture focuses on building core electronic structure algorithms from first principles.

Key topics covered include:

• Formal mathematical foundations of electronic structure theory and electron density representation

• Numerical integration grids and exchange-correlation functional evaluations

• Construction and convergence of the self-consistent field Hamiltonian matrix

• Algorithms for ground-state energy calculations and potential energy surface mapping

• Gradient-based geometric optimizations and atomic coordinate adjustments

• Transition state identification and numerical modeling of elementary chemical steps

Every derivation is accompanied by clean, modular code examples designed to illustrate numerical stability, basis set expansions, and matrix diagonalizations. Whether your objective is to analyze molecular orbitals, investigate potential energy landscapes, or understand the computational mechanics behind modern density functional theory, this text provides the requisite theoretical grounding and algorithmic tools.
