Wang-Landau method

Extensions

The Wang-Landau method has inspired a number of simulation algorithms that use the same strategy in different contexts. For example:

• Inverse Monte Carlo methods (Refs 4-6)
• Computation of phase equilibria of fluids (Refs 7-9)
• Control of polydispersity by chemical potential tuning (Ref 6)

Computation of phase equilibria

The Wang-Landau procedure can be adapted to compute different thermodynamical potentials. In the original paper the entropy is computed as a function of the internal energy.

For instance, in Refs 7-9 it is shown how to sample the Helmholtz energy function as a function of the number of particles, $N$, for fixed conditions of temperature and volume.
