Abstract
The goal of the proposed research is to introduce new improvements in molecular dynamics simulation of macromolecules that increase the accuracy and efficiency of present-day simulation approaches. We primarily aim to: i) improve algorithms for integration of classical and quantum equations of motion by further developing symplectic algorithms based on analytical treatment of high frequency motions, ii) take into account the quantum effects in dynamics of light particles via wave-packet propagation methods and a newly developed density functional theory approach, and iii) improve the treatment of the solvent in molecular dynamics simulation by developing explicit/implicit solvent methods in which the hydration water is represented explicitly while the surrounding bulk water is represented implicitly. The proposed methodological improvements should significantly extend the scope of presently used algorithms in terms of length- and time-scales and thus contribute to the general applicability of molecular dynamics simulation algorithms. The simulation results of selected examples will facilitate the understanding of some fundamental problems in molecular biology.
