John Harding

This lecture will cover:

• Outline of the basic problems of using long ranged forces
• Rough and ready approaches to calculating long ranged forces
• The Reaction field method for continuum environments
• The Ewald sum for calculating electrostatic energy and forces in periodic simulations.
• The Hautman-Klein Ewald method for system with 2D periodicity
• The Smoothed Particle-Mesh Ewald method.
• The Fast Multipole method for long ranged electrostatics.
