The Lennard-Jones 12-6 potential (LJ) is arguably the most widely used pair potential in Molecular Simulations. In fact, it is so popular that the question is rarely asked whether it is fit for

The Lennard-Jones potential is a relatively-simple mathematical model describing the potential energy \(V_{LJ}\) between a pair of neutral atoms as a function of both the distance in units of radii where the potential is zero \(\sigma\) (sigma) and the maximum depth of the potential well \(\varepsilon\) (epsilon). Lennard-Jonesov potencijal. The Lennard-Jones potential (or 12-6 potential) is a mathematically simple model that describes the interaction between two non-bonded and uncharged atoms (known as the van der Waals interaction). It was first proposed in 1924 by British physicist Sir John Edward Lennard-Jones … 2018-05-18 The Lennard-Jones 12-6 potential (LJ) is arguably the most widely used pair potential in molecular simulations.

It is the joint e orts of both Hooke’s potential and the Lennard-Jones potential that enables us to model a solid at the molecular level. In MD simulations, physical quantities are expressed in dimensionless or reduced units [25]. The Lennard-Jones potential is commonly used to represent hard-sphere repulsion and van der Waals attraction, but it is not easily integrated into continuum mean- eld equations for the electrical double layer. Here, a double Yukawa potential is t to the Lennard-Jones interaction, and the double I found (wikipedia) that the Lennard-Jones potential has it's minimum at a distance of. r = 2 1 6 σ.
