About the Institute for Advanced Physical Studies
The Institute for Advanced Physical Studies is a research center for studies in physics and related fields. It is a scientific institution which performs its research and educational activities independently or in partnership with other academic institutions. Progress in science often happens at the border of different specialized areas of competence. Hense IAPS performs interdisciplinary research on topics which borrow ideas from physics, chemistry and computer science. This is achieved in close collaboration between different research groups and by joining efforts with external to IAPS organizations. The obtained results from some investigations in research areas as mathematical physics, nuclear physics, machine learning and others are intended for implementation in the design and fabrication of practical devices in partnership with technological companies.
