This repository contains all computational resources that were used for computations in the aforementioned publication.
All compuations were done with small C++ programs based on the deal.II finite element library, freely available at https://www.dealii.org and https://github.com/dealii/dealii. See https://www.dealii.org/current/readme.html and https://www.dealii.org/current/doxygen/deal.II/Tutorial.html for more information about how to install deal.II and run a program based on deal.II.
The repository structure is as follows:
This subdirectory contains the sources for a program computing the
effective permitivity tensor with the help of the cell problem and
averaging. Parameter files for two prototypical configurations (nanotubes
and nanoribbons) used in the publication are located in the prm
directory.
This subdirectory contains the sources for a program computing the spectrum
and associated coupling constants for the corresponding eigenvalue problem.
Parameter files for two prototypical configurations (nanotubes and
nanoribbons) used in the publication are located in the prm directory.
Both programs are written in the form of simple deal.II example steps,
simply configure via cmake . and compile via make. After successful
compilation an executable sobek is located in a run directory. Simply
copy and rename one of the two example parameter files to run/sobek.prm
and invoke the executable.
