Finite-Size Error in Many-Body Simulations with Long-Range Interactions
Finite-Size Error in Many-Body Simulations with Long-Range Interactions
We discuss the origin of the finite-size error of the energy in many-body simulation of systems of charged particles and we propose a correction based on the random-phase approximation at long wavelengths. The correction is determined mainly by the collective charge oscillations of the interacting system. Finite-size corrections, both on …
