- What is the so called first-principle or ab-initio calculation?
It contains a very short summary of many-body quantum mechanical problem.
PDF version --- Google Colab version - What is the density functional theory (DFT)?
It contains an introduction to DFT such as the HK theorem, KS orbital approach, and XC functional
PDF version --- Google Colab version - How to approach the theory of solid from a DFT perspective?
It contains introductory remarks on pseudopotential, reciprocal space, Brillouin zone, k-points, plane-wave expansion, Bloch thorem, etc.

Here, you will find lecture notes from the coursera course Density Functional Theory. These notes are available as jupyter notebooks (Google colab) or as PDF format.
- Week 1: From the Many-Body problem to Density Functional Theory
PDF version --- Google Colab version - Week 2: From density to the Kohn-Sham world
PDF version --- Google Colab version - Week 3: Approximating XC functionals and strategies for solving KS equations
PDF version --- Google Colab version
These two notes are about electromagnetic wave propagation through an optical medium. The first note is a review of Maxwell's equation in microscopic and macroscopic formulation. Then in the second note, we go deeper into the nonlinear wave equation in the frequency domain
