Improved local lattice approach for Coulombic simulations.
An improved approach to the simulation of strongly fluctuating Coulomb gases, based on a local lattice technique introduced by Maggs and Rossetto [A.C. Maggs and V. Rossetto, Phys. Rev. Lett. 88, 196402 (2002)], is described and then tested in a problem of biophysical interest. The low acceptance rates for charged particle moves in regimes of physical interest are increased to a serviceable level by use of a coupled particle-field update procedure in the new method. Sensitivity of the results to lattice discretization effects is also studied using asymmetric lattices.
