Examples are discussed in Sections 7.3 and 8. When large damping coefficients are used, as one would for the implicit modeling of solvent molecules, the method LN is superior, with LM closely following. However, with mild damping of 0.2 ps −1, LM produces the best results, allowing long time steps of 14 fs in simulations containing explicitly modeled flexible water. In the context of molecular dynamics ξ is called a ‘reaction coordinate’, and is chosen to be the set of variables which evolve on a slower time-scale than the rest of the dynamics. The projection space could be replaced by a general smooth k-dimensional manifold as considered for particular examples in [FKE10, Rei00].

An important reason for looking at this problem in two dimensions is that it then becomes much easier to visualize the configurations (which is one of the voluntary exercises).

A Molecular (Langevin) Dynamics Re: Molecular Dynamics or Langevin Dynamics. From: Marc Q. Ma (qma_at_oak.njit.edu) Date: Wed Apr 27 2005 - 12:39:29 CDT Next message: Giovanni Bellesia: "Re: Molecular Dynamics or Langevin Dynamics" D. Frenkel and B. Smit, Understanding Molecular Simulation, From Algorithms to Applications (Academic Press, 2002) M. Tuckerman, Statistical Mechanics: Theory and Molecular Simulation (Oxford, 2010) M. P. Allen and D. J. Tildesley, Computer simulation of liquids (Oxford University Press, 1987) D. C. Rapaport, The Art of Molecular Dynamics 1.1 Molecular Dynamics Molecular dynamics is a computational tool used to examine many-body systems with atomic resolution. This technique is frequently used in the eld of computational chem-istry to obtain atomic trajectories from which one may extract properties comparable to experimental observables. Molecular dynamics simulations of biomolecular processes are often discussed in terms of diffusive motion on a low-dimensional free energy landscape F(𝒙). To provide a theoretical basis for this interpretation, one may invoke the system-bath ansatz á la Zwanzig. Goal: Use normal modes partitioning of Langevin dynamics for kinetics and sampling for implicitly solvated proteins.
