Novel Theoretical Advances on Quantum Systems in Chemistry, Physics, and Biology

This book contains peer-reviewed contributions based on talks presented at the 27th International Workshop on Quantum Systems in Chemistry, Physics, and Biology (QSCP-XXVII) held in Paris, France, in July 2025. It showcases cutting-edge research across five major themes: foundational advances in quantum theory and computational methodologies; atomic and molecular structure explored through high-resolution spectroscopy and spin dynamics; quantum simulations of reaction mechanisms and charge transport; modeling of clusters, polymers, and materials with applications in energy and electronics; and quantum effects in biological systems, including biomolecular dynamics, chromophore photophysics, and quantum biology. This book reflects the interdisciplinary nature of QSCP, bridging theoretical innovation with experimental relevance in chemistry, physics, and life sciences. This book is an useful resource and is aimed at advanced graduate students, academics, and researchers, both in university and corporate laboratories, interested in state-of-the-art and novel trends in quantum chemistry, physics, and biology, and their applications.
