Many-Body Effects and Electrostatics in Biomolecules

Qiang Cui is professor of chemistry at the University of Wisconsin-Madison, USA. He is interested in developing theoretical/computational methods for the analysis of biomolecular systems, especially concerning chemical reactions in enzymes, energy transduction in biomolecular machines, and, more recently, interaction between biomolecules, lipids, and inorganic materials. Markus Meuwly is professor of physical and computational chemistry at the Department of Chemistry of the University of Basel and adjunct research professor at Brown University, USA. He is interested in developing computational/theoretical methods for quantitative atomistic simulations, specifically multipolar force fields and reactive processes in complex systems.

"This book is a state-of-the-art report on the description of molecular energetics using force fields, which are the most critical element in computer simulations of biomolecular systems. The 16 chapters, written by leaders in the field, provide in-depth reports on all important current issues, including the representation of polarization, quantum mechanics-based force fields, and coarse-grained approaches for RNA, DNA, and membranes. This is an important reference for anyone involved in computational studies in chemistry and biology, especially those who want a deeper understanding of the underlying representations of intra- and intermolecular energetics."—Prof. William L. Jorgensen, Yale University, USA
