Electrostatics#

Examples demonstrating GPU-accelerated computation of long-range electrostatic interactions in periodic systems using Coulomb, Ewald summation, and Particle Mesh Ewald (PME).

These examples show how to:

  • Compute direct Coulomb interactions (damped and undamped)

  • Use Ewald summation for periodic systems with automatic parameter estimation

  • Apply Particle Mesh Ewald (PME) for O(N log N) scaling

  • Work with neighbor list and neighbor matrix formats

  • Perform batch evaluation for multiple systems

  • Leverage autograd for computing forces and gradients
