Abstract

Nowadays, computer simulations are much more than a simple auxiliary tool in Physics and have become a new and independent form of investigation and understanding of physical phenomena. We formed a group of experienced researchers, Prof. Maurice de Koning, Prof. Edison Zacarias da Silva, Prof. Alex Antonelli, of the Instituto de Física Gleb Wataghin of Unicamp, and Prof. Miguel San Miguel of the Instituto de Química of UNICAMP, who have been working actively in the use of computer simulations for the study of structural, electronic, dynamic and thermodynamic properties of complex and nanostructured materials. In our research we use various techniques that are the state of the art for these studies, from formulations of first principles that are based on the Density Functional Theory (DFT), as well as molecular dynamics and also classical and quantum Monte Carlo methods. All these methods require increasing computational capacity. In the last 5 years, our research has been carried out using the computational cluster acquired through previous aid obtained from FAPESP, mainly the thematic project (Process No. 2010/16970-0), which we obtained in April 2011. This equipment is already outdated and several of its components are presenting faults that in the near future will represent a serious reduction of the computational power of the equipment, since several of these components are no longer manufactured and cannot be replaced. The main goal of this project is to acquire new computational cluster so that we can continue our research within a high level of international competitiveness. In addition, this request includes the replacement of personal computers, which are essential for the analysis of the results of computer simulations, as well as the dissemination of our results through scientific articles and participation in scientific conferences.
