# exp2d
Python/C code for simulation of exciton-polaritons in artificial 2D lattices.

**Jupyter notebook interactive examples**

``linear-farfield.ipynb``: Calculation of the far-field radiation from a polariton lattice. Example for the Lieb lattice 
is below (Fig.S9a of the Supplementary Material of Ref.[1]):

``linear-tetm.ipynb``: Linear spectrum in presence of a TE-TM splitting. For, example, 15th mode for the Lieb lattice at (kx,ky)=(0,0) is presented below.

``nonlinear-pump.ipynb``: Nonlinear evolution in presence of the TE-TM splitting and a coherent pumping.

**Supplementary files**

``README.md``: this file.

``exp2d.py``: Python module containing function definitions etc.

``exp2d.c``: C library (used by ``linear-farfield.ipynb`` and ``nonlinear-pump.ipynb``).

``Makefile``: Makefile to compile the supplementary C library (libexp2d.so produced as an output).

``examples``: A folder containing animation examples.

**Installation**

1. Clone:
    ```
    $ git clone https://github.com/drgulevich/exp2d.git
    ```
2. Make:
    ```
    $ make
    ```
3. Use:
    ```
    $ jupyter notebook linear-farfield.ipynb
    $ jupyter notebook linear-tetm.ipynb
    $ jupyter notebook nonlinear-pump.ipynb
    ```
The provided ``makefile`` is suitable for compilation on Linux machines. Modify the file accordingly to suit your needs. On MaC systems the flag
``-soname`` for compilation of the C shared library may need to be replaced by ``-install_name``.
