Preparing for public release

The purpose of this fork is to prepare the HoloLattices package for public release, in order for it to be available for community for future holographic projects.

The work is in progress. The main additions will be:

• Interactive Jupyter Notebook based examples in the tutorial section
• Interfaces with Mathematica and tutorial on how to export the equations of motion
• Extra module with non-epriodic boundary conditions
• Complete write up of the manuscipt (now Manual) describing the package, to be published along with the package itself
• PyPI integration

Stay tuned!

HoloLattices

A generic code design for to solve the problems typically arising in applications of holography to condensed matter systems. It consists of a set of initialization blocks, which include importing the form of equations from Mathematica (or elsewhere), setting up the grid and choosing the initial solution and the parameters of the problem; and the internal loop, where the solution is found after several iterations.

This code has successfully been used for publication purposes, such as for the paper Isolated Zeros Destroy Fermi Surface in Holographic Models with a Lattice

Setup Jupyter for the interactive examples

• Fistly, create a new virtual environment outside of the distribution tree with virtualenv holo-env

  .
  ├── holo-env
  └── HoloLattices

• Jump to root HoloLattices directory and activate it

  source ../holo-env/bin/activate

• Then setup the package with pip install . in the root direcotry.

• The virtual environment is ready, (you will be able to deactivate it with deactivate)

• Now setup the custom IPython kernel for Jupyter ipython kernel install --user --name=venv

• This kernel will now be visible among choices in the top-right corner of Jupyter Notebook or VSCode (after restart)

There are a set of tutorial codes available

For developers

The repository includes Jupyter notebook. In order to track it correctly, make sure to include the local .gitconfig into your Git configuration with

git config --local include.path ../.gitconfig

See https://stackoverflow.com/questions/18329621/how-to-store-a-git-config-as-part-of-the-repository and https://git-scm.com/docs/git-config#_includes

Make sure to update jupyter in order to avoid errors in filter implementation.
