QUEST

QUantum mechanics Enabled Simulation Toolset (QUEST) is a collection of C++ classes and functions for simulation and design of nano-scaled devices using quantum mechanical tools such as Non-equilibrium Green Function (NEGF) formalism. This library provides a common framework for NEGF so that it can be used with any empirical tight binding, k.p model, extended Huckel method and density functional theory codes. This library also includes a generic empirical tight binding model and a k.p model which can be extended for any material with known parameters.

Unlike most of the quantum transport tools available out there, QUEST is a not a predefined simulator for a predefined problem in a predefined device structure. Rather, it is a flexible toolbox that allows users to write their own simulators best-suited for their own problems.

Deep down, QUEST is a C++ library that uses BLAS and LAPACK for computation. Yet, QUEST provides both C++ and Python interfaces so that one can choose between the elegance of C++ and ease of Python.

Dependencies

The following libraries are needed to build QUEST:

CMake >= 2.8
Boost >= 1.55 (Boost.MPI and Boost.Python)
Armadillo >= 4.x
BLAS+LAPACK (Intel MKL)
Python >= 2.7
Doxygen >= 1.8

Installation

Download and unzip source. Then configure using cmake:
$ ./build config

Make and install using:
$ ./build
$ ./build install ~/

To change installation directory, change ~/ to /your/install/path.

To create documentation do:
$ ./build doc

Documentation

Please see the documentation produced by doxygen. We also have a wiki.
