The Z3 model with the density of states method

Understand

In this contribution we apply a new variant of the density of states method to the Z3 spin model at finite density.

• We use restricted expectation values evaluated with Monte Carlo simulations and study their dependence on a control parameter lambda.
• We show that a sequence of one-parameter fits to the Monte-Carlo data as a function of lambda is sufficient to completely determine the density of states.
• We expect that this method has smaller statistical errors than other approaches since all generated Monte Carlo data are used in the determination of the density.
