Multi-component quantum systems strongly interacting with an environment lie at the core of various physical problems, as for example in the quantum biology. Difficulties in the treatment of those systems have recently been overcome by introducing a transformation of the environment, thus making the problem accessible to DMRG-like algorithms.

In this talk I will present this method, extended to mixed states, now allowing the simulation of such systems at realistic conditions. Obtained results for the time evolution of a dimer coupled to a thermal bath are used to assess the capabilities of the method.
