Force fields and molecular dynamics simulations

Collection SFN12(2011) 169 200C Owned by the authors, published by EDP Sciences, 2011 DOI: fields and molecular dynamics lezInstitut Laue Langevin, 6 rue Jules Horowitz, 38042 Grenoble Cedex 9, FranceThis paper reviews the basic concepts needed to understand molecular dynamics simulations andwill hopefully serve as an introductory guide for the non-expert into this exciting objective of this review is to serve as an introductory guide for the non-expert to the excitingfield of molecular dynamics (MD). MD simulations generate a phase space trajectory by integrating theclassical equations of motion for a system ofNparticles. Here I review the basic concepts needed tounderstand the technique, what are the key elements to perform a simulation and which is the informationthat can be extracted from it. I will start defining what is a Force field, which are the terms composing aclassical Force field, how the parameters of the potential are optimized, and which are the more popularforce fields currently employed and the lines of research to improve them.

Then the Molecular Dynamics technique will be introduced, including a general overview of the main algorithms employed to integrate

5.1 Classical 1D motion under the influence of a potential There are two solutions: x˙ = 0 . (5.4) This is “statics”. This is for Civil Engineers. (Buildings are not supposed to move.) The other is dynamics: mx¨ + dV dx = 0 , (5.5) which when you replace dV/dxby −F(x), is recognized as Newton’s 2nd Law of Motion.

PHYSICS 430 Lecture Notes on Quantum Mechanics

stanford.edu

Although classical mechanics is now regarded as only an approximation to quan-tum mechanics, it is still true that much of the structure of the quantum theory is inherited from the classical theory that it replaced. So we begin with a lightning review of classical mechanics, whose formulation begins (but does not end!) with Newton’s law F = ma.
