nano-archimedes is a Technology Computer Aided Design tool (TCAD) for the simulation of various technology relevant situations involving the dynamics of electrons such as the transport in nanometer scale semiconductor devices (nanodevices) and the dynamics of N-body problems in quantum chemistry. It is based on the Signed Particle Formulation of quantum mechanics, a (computationally convenient) phase-space formalism which can simulate time-dependent quantum problems involving single- and many-body systems.

This work is continuously under development and new features are implemented on a daily basis. The numerical method behind the code is based on the iterative Monte Carlo method for the Fredholm equation of second kind (developed by Prof. I. Dimov, Bulgarian Academy of Sciences) applied to the Wigner equation (Dr. M. Nedjalkov, TU Wien, ViennaWD) and coupled to DFT (Dr. J.M. Sellier, Bulgarian Academy of Sciences). The code/sources are developed and maintained by Prof. Sellier, financially supported by the AComIn project.

nano-archimedes is based on the platform implemented for Archimedes (www.gnu.org/software/archimedes). The code is able to simulate time dependent, full quantum, multi-dimensional phenomena such as wave phase breaking and single electron ballistic transport with open boundary conditions, electron dynamics in molecular systems, etc.

nano-archimedes runs both on serial and parallel machines and the parallelization scheme is based on MPI and OpenMP - two standard libraries for parallel calculations. The code is entirely written in C and can compile on a huge variety of machines without any particular effort. It is truly cross-platform.

Many results have already been presented in conferences (e.g. LSSC, IMACS, SISPAD, IWCE, etc) and are submitted for publications. We post part of the results once they are published on this website.
