Description
We study new developments for the Density of States (DoS) method to simulate systems
affected by the complex action problem. In particular we use the functional fit approach
(FFA). It consists of a restricted Monte Carlo simulation with an additional Boltzmann
factor, which allows one to explore the DoS for a given part of the spectrum. We
fit the simulation data with a known function to obtain the parameters of the DoS.
We apply the approach to two model systems: 1) The SU(3) spin system with a chemical potential; 2) The SU3 gauge theory with static quarks. We discuss the technical challenges
and the potential of FFA DoS.
