Development of simulation package 'ELSES' for extra-large-scale electronic-structure calculation

Abstract

An early-stage version of simulation package ' ELSES' (Extra-Large-Scale Electronic-Structure calculation) is developed for electronic structure and dynamics of large systems, particularly, nm-scale or 10nm-scale systems (www.elses.jp). Input and output files are written in the Extensible Markup Language (XML) style for general users. Related pre-/post-simulation tools are also available. Practical work flow and example are described. A test calculation of GaAs bulk system is shown to demonstrate that the present code can handle systems with more than one atom species. Several future aspects are also discussed.
