Notes on kernel density estimation
With a collection of data, we may want to extract or estimate the underlying distribution model. For example, we have the collection of house price in a certain area, we want to have an idea about how the house price in that area is distributed. However, without a priori knowledge...

Notes on occupational short-range ordering in crystal
When multiple atomic species (including vacancies) coexist on the same crystallographic site, it immediately brings up a question - say, we have species A and B sharing the same site, then do we have clustering of A and B in separate domains, or do we have A and B preferring...

Build package with conda recipe
A minimal working example
There are indeed instructions and tutorials about how to build conda packages (which we can then install easily through conda, e. g. by simply executing ‘conda install …’ from command line) with conda recipe. However, as a beginner to conda build, it was really difficult for myself to find the...

Notes on CUDA programming II
Matrix multiplication
First of all, we may need a review for the very basic CUDA programming and GPU execution principle. Here, I want to use the diagram below to demonstrate the threadings on GPU with a very simple array addition operation example.

Notes on CUDA programming I
Preparation
To understand and implement CUDA codes in practice, the very first step is to understand the allocation of threads on GPU. Fundamentally, threads are basic units on GPU where computation can happen in a parallel way. To the first level, threads are grouped into blocks, either in a 1D, 2D...

Notes on magnetism - II
Magnetic ions in crystals
Talking about the magnetism of ions in crystals naturally brings us out of the atomic physics picture which we previously based ourselves in when discussing the free atom and ions (see previous note by clicking me!). Also, for sure we should turn to the many-electron scheme instead of a single-electron...

Notes on magnetism - I
Magnetism of free atoms and ions
To understand the magnetism of free atoms and ions, we may go through several stages, as follows,
Hartree approximation - electrons are treated in a non-interactive manner.
Beyond Hartree - interaction between electrons is taken into account.
Spin-orbital coupling.
Hyperfine interaction - the interaction between electrons and nucleus.

A silent refrigerator
The working principle of Einstein’s refrigerator
All refrigerators running with gas relies on the principle that the evaporation of liquid to its corresponding gas form will take heat from surroundings. After evaporation, the gas should be liquefied back to liquid form to finish the cycle, and of course, the process of liquefaction will emit heat. That’s...
