A light and fast C++ library for the universal model of weak antilocalization.
Weak antilocalization (or localization) is a macroscopic manifestation of quantum interference. The wavefunction of an electron in a disordered 2D system (e.g. semiconductor thin films) can interfere with itself and make the electron a little bit more localized (weak localization) or a little bit more mobilized (weak antilocalization). In experimental settings this effect can be probed by measuring the resistance of the sample in the presence of an external magnetic field (magneto-resistance). These measurements can give us useful information about the electrons and their spins. This library provides a numerical model of weak antilocalization based on semiclassical Boltzmann transport which is valid under a wide range of conditions (universal).
The code is divided into two separate parts: the Uniwal library and the UniwalApp application.
Once installed, the library can be used in other applications or programs of your own.
The application is just a sample code to show how to use the library and how to fit experimental data.
- cmake: used to organize the project and configure make files so that your compiler is successful in compiling the library and the application.
- gtest: is from Google and is used for unit testing. It is automatically fetched (downloaded and installed) by cmake.
First download the current repository and change your directory to the root uniwal folder where this README.md file is located.
git clone https://github.com/smfarzaneh/uniwal.git
cd uniwalThen you would need to compile the source code into binary files and executables.
The following shell commands compile both Uniwal and UniwalApp and puts the binaries inside the build/ subdirectory.
cmake -S . -B build/
cmake --build build/This is optional. If you want to run the unit tests on the library to make sure everything works on your system as it's supposed to, run the following command
ctest --test-dir build/ --output-on-failureTo see the library in action run the following command to execute the UniwalApp application.
./build/UniwalApp
