The spin-boson model is a paradigmatic model for the emergence of dissipation and decoherence in quantum mechanics and has motivated a lot of research in the past and present [1]. Still, no closed analytic solution of the model*s Hamiltonian is known. On the other hand, it is known that the dynamics of the model is fully determined by the so-called spectral density of the environment [1]. Here, we propose a method to simulate environments with continuous spectral densities in the setup of trapped ions using mixed species crystals and a small set of damped modes. In comparison with previous proposals [2] this has the advantage of reducing the experimental complexity and therefore moves the study of the statistical mechanics of the spin-boson model firmly into the realm of current ion trap technology.
